Selecting a CPU
CPU (central processing unit) is the main component of the computer, which determines its performance. Selecting a CPU for desktop and notebook PCs is a very responsible step. In the case of buying a CPU with a lack of capacity, you can not enjoy your favorite 3D-game, it certainly would slow down. How to choose a CPU? Which CPU is better? Below we list the main characteristics of the CPU, to which we should pay attention when buying a CPU.
Manufacturers of the CPU
First of all, note the manufacturer of the CPU. At present, modern CPUs are marketed under three brands: Intel, AMD and VIA Technologies.
Performance of the CPU
As models of the processor, then the entry-level computers use VIA C3 (VIA Technologies), CPU Duron (AMD), CPU Celeron (Intel). High-performance systems use Pentium III / 4 (Intel) CPU or Athlon (AMD) CPU.
As it is known, CPU's speed is determined by its clock frequency. CPU clock speed for the entry-level computer systems should be at least 900-1000 MHz, and for high-performance systems - 1,5-2 GHz or higher.
It should be noted that not only the clock frequency determines the performance of the CPU. Architecture of the CPU is also very important. For example, the CPU performance AMD Duron 1,3 GHz greatly exceeds the performance of Intel Celeron 2,0 GHz.
When buying a CPU you should consider the form factor, which should coincide with the type of CPU socket on the motherboard. Modern processors have the following Chassis: Socket 370 FC-PGA (Intel Celeron up to 1400 MHz, VIA C3, Intel Pentium III), Socket 423 / 478 (Intel Celeron 1700 MHz or higher, Intel Pentium 4), Socket A (AMD Athlon / Duron ).
CPU's future
As we know from the history of the development of processors, previously increasing of CPU's performance was achieved by increasing its clock frequency. But with increasing frequency heating of the CPU and the risk of overheating the processor increases significantly. And in this case nor heat, nor the use of very thin transistors don't help. Solution was found not so long ago - users have been proposed multicore CPU. Multicore processor is a "two CPUs in one", ie location on a single chip multiple cores (hence the dual-core processor, quad-core processor, etc.).
Currently, manufacturers of multi-core CPUs seek to the improvement of processors and to reduce it's cost. The world's leading manufacturers of Intel and AMD processors today have a large selection of multi-core counterparts, because the future belongs to it.
