How to choose a processor for the computer

When choosing a processor for a computer should first determine its future use.

How to choose a processor for the computer: basic selection options

How to choose a processor for the computer

When choosing a processor, you need to pay attention to the following specifications:

  1. Socket (especially important if the processor is changing and the motherboard payment – no);

  2. Processor generation;

  3. Power (power consumption);

  4. Clock frequency;

  5. The number of cores and computing threads;

  6. Process technology;

  7. Dissipated Thermal Power (TDP);

  8. The presence of a built-in graphics accelerator.

Thus, when choosing a processor for a home computer in upgrade time must be based on characteristics motherboard, power supply and peripheral hardware providing.

Socket

Socket

A socket is a socket in which a processor is installed. Exactly it determines whether the desired chip can be mounted in an existing one motherboard, or else have to buy a new one.

Since this is the most important parameter, then the search for a new CPU needs to start by determining which socket installed on the motherboard. This can be done through disassembling the system unit or using a program like AIDA64.

If you plan to replace the motherboard, then you can pick the desired socket in advance. Today the most widely are found:

  1. Intel LGA1150 is a simple configuration for office and home PCs. Supports low-performance processors with integrated graphics;

  2. Intel LGA1151 – a more recent configuration for all the same PCs, with just a bit more performance. Almost all modern processors of the Core series are available on this socket;

  3. Intel LGA2011-v3 – the most powerful configuration. Suitable for a gaming computer or just a “top” system. Is different high cost – both motherboards and processors;

  4. AMD AM1 is a very low-power, but energy-efficient platform. For office PCs, laptops, etc .;

  5. AMD FM2 / FM2 + is another low-power and low-cost platform. Designed for use with AMD processors that are not equipped with a built-in graphics accelerator;

  6. AMD FM3 + – almost all AMD processors are available for this socket.

Processor generation

Processor

Everything is very simple here: the higher, the newer generation of the processor – all the better. It determines not only the performance of the chip, but also its energy consumption, degree of heating and a number of other parameters.

Current generations of Intel processors:

  1. Haswell (fourth);

  2. Broadwell (fifth);

  3. Skylake (sixth);

  4. Kabu Lake (seventh).

The latest generation of AMD processors:

  1. Richland

  2. Vishera;

  3. Kaveri.

Power (power consumption) of the processor

Processor performance is directly dependent on its power. But, at the same time, the higher the power consumption of the chip – the stronger it is heats up. So, for the most powerful game processors usually performance of the classic cooling system is not enough, used liquid.

If you do not plan to change the computer’s power supply, you must choose a processor whose power consumption in watts or matches the power of the old, or just fit into power supply performance.

It is worth remembering that the most powerful processors can consume up to 200 watts of electricity.

Clock frequency

This parameter determines the peak processor performance. However, often these figures are very approximate and indirect value. So, old processors with a clock speed 3.5 GHz performance is much lower than with new same.

In addition, in the parameter “Clock frequency” most often indicates the overall processor performance. However series chips Intel Core can work in Hyper-Threading mode, in which computation speed increases by about 1.5 times. And when overheating throttling is observed – a drop in the clock frequency.

However, buying processors with a clock speed of less than 2.0 GHz is not justified. And for desktop systems, especially gaming, this the parameter should be even more than 2.7 GHz.

Number of Cores

Number of processor cores

The number of cores is also very important for performance. the processor. However, it rather determines how many tasks can simultaneously execute the chip, and not how fast it will be with to cope with them.

However, in this case, the more cores – the better. Limitations if there are any, they are insignificant. But the standard for A home or gaming PC is 4 cores. Thanks to modern they can be extrapolated to technologies – up to 8 computing threads – to further increase the speed of the computer.

10-core processors like the top-end Intel Core i9 at home or gaming computers are not particularly needed, as they provide only insignificant increase in comparison with modern quad-core Intel Core i7.

Process technology

The process determines the degree of heating of the processor. And than he less is better. For example, modern Intel Core processors Kabu Lake are manufactured using a 14-nanometer process technology and therefore heat less than 22nm Haswell.

Thus, the “fresher” the processor, the less its manufacturing process. and weaker heats up.

Power Dissipation (TDP)

This parameter determines how well the processor adapted to heat dissipation. The smaller this parameter, the it’s better. However, you can ignore this parameter.

Unless processors with a large TDP value (more than 65 watts) It is recommended to equip with a more powerful system than the stock one. cooling.

The presence of a built-in graphics accelerator

The presence of an integrated graphics accelerator

The integrated graphics accelerator determines if the computer can work without a discrete graphics card. If you plan to use PC for web surfing or as a “typewriter”, then a separate “see” is simply not needed, it will be sufficiently integrated into CPU.

For games, 3D rendering, working with video files, editing images and similar purposes requires a discrete graphics card. IN in this case, the processor with integrated graphics accelerator does not needed. But the video card built into the chip doesn’t hurt – the operating the system itself will determine what to draw.

Thus, the presence or absence of a graphics accelerator in the processor is nothing more than a matter of personal preference.
