The ninth generation processors released in 2018 and 2019 were named Coffee Lake Refresh.

What is a PCIe or PCIe lane? PCI stands for Peripheral Component Interconnect. This is the standard interface for connecting the graphics card and many of the onboard components to the mainboard. PCIe, short for PCI Express, is the current standard and has replaced the common PCI interface until 2004. It allows fast data exchange, for example between the CPU and graphics card. PCIe uses so-called lanes for data transmission, each consisting of four lanes of conductors or cables. Two of the four traces are used for sending data and two for receiving data. To increase data throughput, it is possible to combine individual lines. For example, a graphics card with up to 16 lines can be connected.

What are CPUs?

CPU stands for Central Processing Unit, which means the central processing unit. Other common names are central processing unit, processor unit, main processor or simply processor. Colloquially, a CPU is sometimes referred to as a computing core, which is not quite true.

The CPU is the processing and control center, or heart and brain of a computer. It controls all important processes. A CPU can consist of several cores called processors. This is the CPU processing unit. They work in parallel but independently of each other. Multiple cores in a processor means more computing power.

In a computer, the CPU is a separate component. It is plugged into a socket, which in turn is on the motherboard sitting. The connection between the socket and the processor is made using many small pins, called pins. Windows PCs have the option to replace the processor. With Apple computers, changing to a different processor is not easy. The CPU in Apple devices is soldered, such as laptops or mobile devices such as smartphones and tablets.

Modern CPUs are mostly called microprocessors. These are processors in which all the processor circuits are housed on a microchip or single circuit. Before the microchip was invented by Intel in 1971, processors could fill larger cabinets.

CPU structure - how does the processor work?

A CPU consists of several elements. The main components of the processor perform different tasks.

Control unit: The control unit, also known as the program control unit or control unit and in specialist circles, the control unit or CU, controls the processing of CPU commands. It receives and translates instructions from processor memory and performs tasks. In addition, the control unit is responsible for coordinating the other components of the processor and the various components of the computer.

Arithmetic Logic Unit: Arithmetic logic unit has the abbreviation ALU for Arithmetic Logic Unit. As the name suggests, the ALU performs arithmetic and logical operations. The ALU is told how to perform this operation by instructions from the control unit, which are sent to the data in the CPU registers.

It is important to know that computers work with a binary system. All arithmetic operations or all mathematical calculations are performed in a binary system. In addition, logical operations (decisions that the CPU makes based on calculations) are represented in a binary system and implemented in electrical circuits. Circuits are also based on a binary system, they only know two states: According to the numbers 1 and 0, they are on and off.

What is a binary system? It is also called dual system or two system. The binary system has only two states and only two digits, 0 and 1. All numbers are represented by two digits in a form called binary numbers. For computers, the binary system is the basis for information processing and data transmission. Bit stands for binary digits are the digits of a binary number or binary sequence and the smallest unit of binary information.

CPU registers: CPU registers serve as buffers for data to be processed. Memory works at breakneck speed.

Bus: The data bus is the connection between units connected to the rear derailleurs. The processor bus is used to transfer information and is a high-speed data path. They transfer instructions and data in the CPU between the various components of the processor, for example between the ALU and CPU registers.

Clock cycle

The CPU works according to a certain scheme. The clock cycle consists of four steps:
  1. Fetch: Translated from English, fetch means to take. The processor does this in the first step. The CPU register stores all commands sent from the program to the processor. Since several million commands are regularly sent to the CPU, it manages all commands as soon as they arrive. The CPU knows where to find the next instruction to process. First, the processor fetches instructions from memory.
  2. Decode: Instructions come from a program in a "language" that the CPU must first decode. It translates instructions and translates them into its own machine language.
  3. Execute: Once the command is fetched and decoded, the real task of the control unit begins. It moves data back and forth, calculates, calculates, and makes decisions. If the calculations are mathematical, they are delegated to an arithmetic logic unit.
  4. Writeback: The step name translation describes what happens now - the result of the Execute process is returned to memory.
This all happens during one clock cycle. CPU work can be compared to assembly line work, with a defined high clock speed. After all, no one wants to wait long for a program to execute input. clock frequency or clock rate is therefore an important variable in relation to processor speed.

Processor related terms are explained in an understandable way

Many terms related to CPU are already explained in the text and in the glossary. This section describes some of them in more detail or provides explanations for other processor-related terms.
  • Socket: A socket is a slot for the CPU on the motherboard. AMD and Intel sockets differ significantly.
The socket must match the processor. AMD and Intel processors differ among other things in the pin position. With AMD CPUs, the contact pins are attached to the processor. It is plugged into the socket. Intel processors, on the other hand, do not have their own pins. Instead, the pins for plugging in the CPU are located directly on the socket.
  • Processor core: The processor core – known as the core – forms the central processing unit of the CPU. This includes the arithmetic logic unit, CPU registers and control unit. An interrupt decoder, cache, floating point unit, and memory management unit (a unit that manages memory) are optionally housed in the core. Modern processors have more than one core. The term multi-core or multi-core processor means a microprocessor with more than one complete processor core on the chip.
  • Throttling: Throttling means to miss a certain beat. The purpose of throttling is to protect the processor from overheating. If the clock rate is not fully exhausted, less heat is generated. The point at which the CPU starts to throttle is set: If the temperature is close to the maximum value of the junction, the processor throttles - it throttles. A 75 percent slowdown, for example, means missing three of the four bars. If the throttling is not enough to cool the processor temperature well below the critical mark, the CPU shuts down.
  • FLOPS: FLOPS is a term that only appeals to absolute tech enthusiasts. However, it sometimes appears in connection with the CPU. FLOPS has nothing to do with CPU errors, but stands for so-called floating point operations per second. FLOPS measures the probability of floating point operations per second. A floating-point number or an equal-dot number refers to the representation of a number in exponential notation - for example 1.45 x 10⁶ notation, not 1.45 million. The only thing that is of interest to the user is that the higher the specified FLOPS value of the CPU, the faster the processor.
  • IPC: IPC is the unit and stands for Instructions per Cycle. IPC indicates how many instructions the processor executes in one clock cycle.
  • Benchmark: Benchmark is an English term and means scale. Benchmarking is a standard process. It identifies performance characteristics and compares them. Benchmarks are used to compare individual PCs or computer components - for example the processor, graphics card, or storage media such as a hard drive.
  • Integrated graphics card: For a computer to display anything at all, it needs a graphics card. Without components, the screen remains black. If the graphics unit is permanently installed in the CPU, you do not need to install a separate graphics card. This saves space in the housing, which is why this solution is often used in laptops. Disadvantages of integrated graphics cards: No dedicated video memory.

Important for gamers: If you want to run complex games on PC, you should not only pay attention to a powerful CPU. The integrated graphics unit (graphics chipset) is not sufficient for a smooth game display in most cases. Newer PC games like Call of Duty are no fun because they stutter and the game crashes sometimes. You need to install the "correct" or dedicated and powerful graphics card.

  • Box and tray: Processors are commercially available in box and tray versions. The box version comes in a stylish original packaging. The tray version is poorly packaged. Delivery is made in an unadorned cardboard box. Packaging is not the only difference between the two versions. Box CPUs are slightly more expensive, but manufacturers usually offer a 3-year warranty. In addition, processors often come with a cooler - the cooler can be purchased separately for the tray version. Another disadvantage of the tray version: it may return, but this is not visible when you buy it.

Which CPU for what purpose?

With so many different processor options, ordinary people can quickly go wrong and choose a CPU that doesn't meet their own requirements. If the processor is too large, the investment will be higher than necessary. If the CPU is too weak, it quickly reaches its limit. Then certain programs run very slowly or not at all. That's why it's important when choosing a computer core to consider the tasks that little computing wonders are supposed to do. The following is a brief overview of the different types of processors with their advantages and disadvantages.

Office CPU

Office PCs are designed to run office applications. Anyone who just does daily work with a computer does not need a lot of computing power and speed. You can surf the web or compose an email with a cheap processor. Using a text or spreadsheet program or watching a video works without delay.

What is a single core? The term single-core can be confusing because it now has two meanings - at least when used incorrectly. Single-core processors, CPUs with only one core, are often referred to as single-core. But sometimes single-core is used as an abbreviation for single-core performance or single-core power. This means something else. Single-core performance provides information about the performance of single-core CPUs with multiple cores - multi-core processors.

There are almost no CPUs with only one core, so-called single-core processors, they are considered outdated and are rarely found. However, a processor with two cores is sufficient for an everyday or office PC. Simple processors have their advantages. They are inexpensive and low in power consumption and heat generation. Complex cooling such as water cooling is not required.

Everyday & Office CPU Pros & Cons

  • Inexpensive
  • Low power consumption
  • Low heat generation
  • Enough for simple application
  • Usually not enough for games
  • Demanding programs don't run or just run very slowly
  • Not future proof
Multimedia CPU

If you want to edit images or crop videos on your computer, you need a processor with high computing power. In addition to high performance, multimedia CPUs are characterized by their speed. Both are indispensable for extensive graphic work.

A processor suitable for multimedia work must have at least six cores. A lot of computing power means hunger for energy. Processors usually consume a lot of power and heat. They are also more expensive than office CPUs.

Advantages & disadvantages of multimedia CPU

  • Strong
  • Support for complex programs
  • Ideal for multimedia applications
  • Future proof
  • Expensive
  • High to very high power consumption
Gaming CPU

If you want to play complex games on PC, you need a gaming CPU. The processor allows for smooth gaming without jerking if other components such as the graphics card are powerful enough. A game processor has at least four cores. More important than core count is individual core performance, known in technical jargon as single core performance.

Pros and cons of gaming CPU

  • Supports a variety of complex games that require high computing power
  • Future proof
  • High single and multi-core performance
  •     High power consumption
What else does a gaming PC need besides a fast CPU?

Gamers in particular pay attention to the performance of certain computer components, not just a fast CPU. The mainboard is the basic building block of every computer. Gamers often prefer AMD processors. Thus, the choice fell on the main board equipped with the appropriate sockets.

If you prefer to play complex games on your PC, you should also make sure that you have enough RAM. Flash memory is called faster than hard disk memory. Data and running programs reside in memory. More memory doesn't just mean shorter loading times. It allows multitasking parallel use of multiple programs.

In addition to the processor unit, the main focus of PC gaming is on the graphics card. It must be strong to ensure smooth play. A good graphics card can only provide attractive graphics if the monitor can display the appropriate image. A prerequisite for a smooth display is that the screen displays up to 144 frames per second - a 144 Hertz monitor.

In addition, SSD hard drives are recommended as storage in gamers' PCs. PCs and programs start up faster from so-called solid-state disks (SSDs) than from HDDs (hard disk drives), which read data from a rotating magnetic disk.

AMD or Intel CPU comparison – no questions for gamers?

For a long time, AMD and Intel were roughly equal in favor of gamers in the CPU rating. For a short time, Intel had the upper hand. In 2017 AMD won the race by introducing the RYZEN generation. RYZEN processors cannot compete with Intel when it comes to single-core performance.

However, in benchmarking, AMD CPUs perform better than Intel processors and convince with top marks in processor comparisons. High multi-core performance. Price is also an aspect that shouldn't be overlooked: AMD processors cost about half the price of Intel CPUs with the same number of cores.

Attractive to professional gamers: Only professional gamers can put Intel above AMD processors in their CPU rankings. Because it is combined with proprietary graphics card solutions, for example when using multiple graphics cards at the same time, CPUs from Intel bring a bit more performance.

Moore's Law only explains

Moore's Law goes back to the American engineer Gordon Earle Moore. As early as 1965, Intel's co-founders predicted that the number of transistors that could be inserted into an integrated circuit of a given size would double every year. The term "Moore's Law" was coined by the American sculptor Andress Mead in 1970. The electrical engineer is one of the pioneers of modern microelectronics.

Incidentally, Moore corrected his original statement in 1975. According to him, the number of transistors in a microprocessor should double every 18 to 24 months. However, Moore's Law does not only mean the doubling of electronic circuits in the processor in a given cycle. At the same time, Moore predicts that component costs will fall, making processors affordable to the general public.

To date, Moore's law has not lost its validity. However, experts suspect that one day it will reach its limit – namely the physical limit. Rapid progress is not possible in the long term. The first mass-produced processor, the Intel 4004 from 1971, had 2,300 transistors installed. Today's CPUs have several hundred million electronic circuits. Roughly every 2 years, manufacturers AMD and Intel bring a new processor to the market.

When does CPU temperature get too high?

Often there are three standard values ​​for temperature:
  1. Processor temperature should not be warmer than 30 to 50 degrees Celsius at idle or with low CPU load.
  2. CPU can reach temperatures up to 90 degrees Celsius under heavy load, maximum load.
  3. Depending on the model, the temperature should not exceed 100 degrees Celsius.
These guidelines are quite general. Actually different values ​​are relevant. When using it, some technical terms are important for temperature measurement. However, the explanation of the technical terminology is simple. Since persistently high temperatures have a negative effect on CPU life, this guide covers this topic and cooling options in detail.

Processor temperature related terms

Various sensors built into the processor continuously monitor the temperature. The temperature measured on the processor heat spreader is called Tcase. This is only of interest to processor manufacturers. This value is used for further processor development.

The temperature in the core is called the tjunction. The term Tcontrol describes the desired temperature. If the measured temperature is above the Tcontrol value, the fan will increase its speed – until it drops below the Tcontrol value again. conjunctionMax means the core temperature at which the core is constrained. More precisely, in this case the power supply to the CPU is cut off. Simply put, this means the processor is turned off.

What affects CPU temperature?

The temperature that the CPU reaches doesn't just depend on the processor and load. Cooling efficiency is also relevant. Not only CPU cooling is intended, but case ventilation as well. If the heat is not dissipated properly, it will accumulate in the computer case. Plus, the CPU isn't the only heat source in the case.

Powerful graphics cards generate heat as well as heat the inside of the computer. Last but not least, ambient temperature plays a role. If the PC is in a warm room or next to a heater, the cooling of a fully charged CPU quickly reaches its limit.

What should not be forgotten is the power supply of the computer. So hot that it has its own cooling system with fan. The fan transports heat away from the computer through specially designed air slots or curves. If the power pack is not cooled, the computer will overheat and shut down after a while.

What temperature can the CPU withstand?

How hot a CPU gets without breaking down varies from model to model. In terms of heat resistance, AMD and Intel processors are not significantly different. Some examples:
  • Tjunction Max for Intel Kaby Lake is generally given as 100 degrees Celsius.
  • The power-efficient Kaby Lake T model, identified by a "T" after the CPU number, reaches the intersection depending on the model. Maximum between 80 and 92 degrees Celsius.
  • AMD sets the maximum temperature for most RYZEN models as 95 degrees Celsius.
  • The exception is the RYZEN 2xxxGE (Raven Ridge) CPU with a maximum temperature of 105 degrees Celsius.
What types of cooling are there?

High temperatures permanently shorten processor life. It is therefore important to ensure that not only the processor is sufficiently cooled, but also the entire system. It may need to be changed to a different type of cooling.

Caution: An overheating CPU causes a system crash or, in the worst case, complete failure.

There are three types of coolers used in processors and other computer components. The goal of effective CPU cooling is to keep the processor temperature well below the Tjunction Max value, or at least maintain it - to protect the processor from damage and to avoid clock rate throttling. Otherwise, a loss of speed will occur.
  • Passive cooling: With passive cooling, the heat sink, for example in a processor, absorbs heat and radiates it to the environment. Fan not available. The cooler does not actively conduct absorbed heat away from the CPU, but only releases it into the environment.
  • Active cooling: With active cooling, the heat sink absorbs the waste heat from the CPU and the fans actively expel warm air from the processor. Warm air flows out of the housing through the ventilation slots, which is why it is important to keep the slots dust free and not to cover them.
  • Water cooling: Water cooling is an active cooling system, but it does not require a fan. One heat sink sits on the processor, the other sits on the inside of the PC case. The latter are called radiators and have multiple blades that increase their surface and area of ​​contact with the environment. The two heat sinks are connected to the hose through which the water is pumped. It absorbs waste heat from the processor and transports it to the radiator. He gave it to the environment. A small fan guides warm air out of the case. The cooled water then flows back into the CPU to absorb the waste heat again.
It is recommended to cool the graphics card separately and effectively. Often the error is made without cooling the graphics card with a view to the development of the desired minimum noise. Graphics card enthusiasts can develop a very high level of noise that can be annoying when using a computer for long periods of time.

Tips: If your CPU and graphics card frequently need to work properly, removing the PC case can help eliminate heat build-up and ensure better heat dissipation. The disadvantage is that fan noise increases PC volume.

Before you buy – which CPU is right for you?

CPU is an important component when it comes to computer speed and performance. To find the best processor for your own needs, there are a few things to consider before you buy.
  1. Compatibility: CPU must match the mainboard. Processors from AMD and Intel differ in pin position. While the contact pins on AMD processors are attached to the CPU, the pins on Intel are in the socket. The CPU socket must match the mainboard socket accordingly.
  2. Purpose: An important aspect when choosing a unit of computation is the primary purpose of the computer. If most office work has to be done, a cheap two-core processor will suffice. Hyper Threading is not necessary. The situation is different when a multimedia application that is predominantly computationally intensive such as video editing is to be run. The CPU must have at least six cores. Hyperthreading is indispensable for fast and smooth processing of graphics applications. Gamers appreciate smooth gameplay. Therefore, complex games need not only a powerful graphics card. The processor must enable the appropriate computing power. Four cores is the minimum. Single core performance is critical.
  3. Number of cores: Four cores are currently considered sufficient for a gaming CPU. If you mainly use your PC for gaming, you should pay attention to the high clock speed of each core. Future computer games will probably require six or eight cores. More cores are future proof. The following already applies to video, audio, and image processing programs: the more cores, the better. The same is true if several programs are frequently running concurrently. Computing power is required here and Hyper-Threading is an advantage.
  4. Clock frequency: Clock speed provides only limited information about CPU speed. Newer models often come with lower clock speeds and still carry more speed than older processors with higher clock rates due to modern chip architectures.
  5. Cooling performance: To prevent the CPU from overheating or shutting down, components must be adequately cooled. AMD processors require up to 250 watts of cooling capacity. Intel CPUs are a bit more frugal, they have a cooling capacity of up to 165 watts. Ideally, cooling works effectively, but as quietly as possible.

Frequently Asked Questions about CPU

Find out the CPU – which processor is installed in the computer?

If you don't know which processor is installed in your computer, you can find out very easily. The easiest way is through the [Windows] + [Pause] key combination in system overview. However, not all keyboards have a pause button.

In this case, right-clicking the small Windows symbol in the lower-left corner of the screen will do the trick. A context menu will appear, click "System" to open settings. By clicking "Info" in the left menu, device information will be displayed - including the processor installed.

How fast is the installed CPU?

The current processor clock can be read on a Windows computer in the task manager. It is possible to open the program independently of the installed version of Windows with the key combination [Ctrl] + [Shift] + [Esc]. Under the "Performance" tab there is an item "CPU", where the current CPU speed is displayed. You can also find other interesting information about CPUs here, for example:
  • Cache level
  • Number of cores
  • Current CPU Usage
  • Process being handled by CPU
  • Number of active threads
How to read processor temperature?

There are two ways to display the CPU temperature: with additional software or with the BIOS. There are many programs, some of which are free, that display and monitor processor temperatures. Some offer mainboard manufacturers the appropriate software for free download on their websites, which displays the CPU temperature, among other things.

Alternatively, the BIOS displays the CPU temperature. Pressing the [F1], [F2] or [Del] key while the computer is turned on – which key is correct depends on the manufacturer – will call up the BIOS. Depending on the BIOS version and manufacturer, the desired information is hidden under "Hardware Monitor", "H/W Monitor", "PC Health", "Health" or similar entries. With the appropriate entry, the processor temperature is displayed under "CPU Temperature".

What is meant by BIOS? BIOS stands for basic input/output system and is part of the operating system as software on the mainboard. The BIOS contains all the basic functions of the operating system and is located on a small chip on the mainboard. This starts the start of the operating system.

What to do if CPU temperature is too high?

If the processor gets very hot, the temperature must be lowered to avoid damage and complete failure. The first step to lowering the operating temperature is to turn off the computer. Removing the casing cover allows the accumulated heat to dissipate better. Cleaning the ventilation slots of dust and dirt will prevent the processor from overheating gradually in the future. If heat can't escape the case, it builds up and quickly causes multiple hardware components to overheat, not just the CPU.

A vacuum cleaner works well for this. The vacuum cleaner is not suitable for cleaning fans and fine fins. It is better to use a compressed air spray with a pipe attachment. Soft brush gently removes dust from fans and circuit boards.

What causes are responsible for excessive temperature? Apart from high ambient temperatures, poor cooling, or heat accumulation in the case, a faulty CPU can be the cause of heat problems. Therefore it is necessary to test the processor for errors. There are many small programs for this purpose. The software in use may overload the CPU. Then a new processor that meets the requirements solves the problem.

Increase CPU performance - how to overclock the processor?

best CPU

Both Intel and AMD provide their CPUs with specified clock speeds. With this clock frequency the processor works reliably and stably in the long run. However, there is a spare, so dealing with overclocking a little more performance can be stripped away from the CPU.

Higher clock frequencies also mean higher power consumption - and a higher power supply also means more heat build-up. Because the conversion of electrical energy does not take place in motion or the like, but in heat. Cooler, the box version often included doesn't do enough to cool an overclocked CPU. If you want to tune your processor, you should think about sufficiently efficient cooling beforehand and purchase and install the appropriate product.

Modern processors shut themselves down for their own protection when they reach a certain temperature. This also happens with overclocked CPUs. However, the maximum clock rate should not be extracted in one step. It is better to increase the processor speed by 10 percent in small steps and see if the system is still running stably and safely. Automatic shutdown of the CPU from a preset temperature reliably prevents hardware damage. However, it does not protect against system crashes and possible related data loss.

Anyone who decides to overclock regardless of the risk and has maintained adequate cooling doesn't have to be a tech professional for CPU tuning. Intel and AMD provide special software that allows easy overclocking of the display:
  • With the Intel® Extreme Tuning Utility, Intel offers free software that monitors and tests the CPU and, if desired, overclocks it. System overview provides information about processor usage and temperature and provides information about main memory, graphics card, mainboard, and operating system. In the tuning area, individual adjustments of clock rate, voltage and turbo boost or boost clock settings take place.
  • If you want to overclock an AMD processor, you can do so with the AMD RYZEN Master overclocking tool - as long as the CPU has an AMD RYZEN processor installed. Hour rates can be set using software and manipulate core speeds individually. Access to the CPU also allows individual cores to be shut down.
Which mainboard socket is installed?

If you want to find out if a new processor is compatible with the installed mainboard, you have several options. The easiest way to get the information you want is to use specialized software, such as CPU-Z Portable or Speccy programs.

Alternatively, on Windows computers there is an option to read sockets through the registry. The registration database, as the registry is called, is the central configuration database for Windows. It contains all the important information for Windows and for the programs installed on it.

The registry editor is started by simultaneously pressing the [Windows key]+[R] key combination and then entering the command "regedit" without the quotes. To get the desired entry, the path HKEY_LOCAL_MACHINE -> HARDWARE -> DESCRIPTION -> System -> BIOS must be opened in the left menu column. In the right column, the "BaseBoardProduct" entry provides information about the designation of the mainboard model. The motherboard manufacturer can be found under the "BaseBoardManufacturer" entry.

What is the difference between Hyper and Multi-Threading?

The term Hyper-Threading has taken the form of Intel, but today it is also common to non-Intel processors. The correct term is Simultaneous Multi Threading, or SMT for short. Hyper-Threading allows better utilization of the CPU core. If the core can only process one thread and has to wait for certain information, time is lost.

With Hyper-Threading, a core can have two or more threads editing at the same time. While waiting for certain data for a task, it switches to another thread and processes it. The core can switch between two or more threads, which means increased performance and speed.

The term multi-threading is often confused with hyper-threading, which is not entirely accurate. Simultaneous Addition does not exist. Multi-threading is used in programs or operating systems. Multiple threads are processed in parallel in one process. The prerequisite is that the operating system supports multi-threading. Multi-threading can even be done without CPU support.

Where can I buy a suitable CPU?

Stationary retail can be an important decision-making aid for gamers. Expert advisors can provide specific advice on finding the best processor for individual needs, or suggest a specific CPU. It is also possible to test the performance of the processor on site. In terms of price, however, stationary trading usually cannot compete with online trading.

In the CPU market, online trading is clearly ahead, not only because prices are often lower. In terms of quantity, the offer on the Internet cannot be terminated. In addition, the online platform provides a variety of dedicated and mostly self-explanatory information about the performance spectrum of each processor. The larger providers offer technical support for their customers.

Good, solid benchmarks are not uncommon on sites. This applies to independent information sites as well as to the manufacturer's information itself. Benchmarks usually allow direct comparison of processor values. Retail can't do that. Other advantages such as round-the-clock shopping or saving time on travel and waiting time favor purchasing on the Internet.

Who offers CPU?

In principle, two providers of PC processors define the market:
  1. AMD: Advanced Micro Devices, Inc. is a US company. Companies in the semiconductor industry have headquarters in Santa Clara, California, and more than 35 locations worldwide. AMD serves the consumer and computing and communications industries. The company develops and sells comprehensive computer chipsets and chips, microprocessors, graphics processors, and chip solutions.
  2. Intel Corporation: The US semiconductor manufacturer is also headquartered in Santa Clara, California. Its European headquarters are in Munich. Among other things, Intel produces special microprocessors or CPUs, other types of microchips for computers, flash memory and WLAN and network cards. With its PC microprocessors, Intel has a global market share of about 80 percent.
