How to choose a processor
The central processor (CPU) is the "brain" of the personal computer. It is he who is responsible for all computer calculations and data processing. Choosing a good processor is not an easy task. Therefore, we want to share with you tips, how to choose a processor and what characteristics it should pay attention to.
Among the manufacturers of processors, the palm branch of the leader belongs simultaneously to two companies, Intel and AMD.
The main characteristics of the CPU:
- Clock frequency. Processor frequency is the speed at which the processor operates. Clock frequency is measured in Hertz (Hz) and the higher it is, the better the performance of the processor. Clock speed of modern processors exceeds 2-3 GHz (gigahertz).
- The number of processor cores. Modern processors have more than one core, but two, three, four, six or more cores. For home PCs that do not require very high performance enough single - or dual-core processor (it's enough to work with documents, multimedia files, many three-dimensional toys). Processors with more cores are needed for "gaming" PC configurations or for professional 3D models.
- The data transfer rate on system bus (system bus frequency, FSB). The higher the bus frequency, the higher the CPU speed (the speed of data transmission in the CPU and out of it). The frequency of the tire is equal to modern processors 800/1066/1333 MHz.
- The size of the system Cache. CPU cache is a fast memory designed for temporary storage of code and data. Appeals to the built-in cache memory take place without wait States, because it operates at the processor frequency. The larger the CPU cache, the more efficient processor.
- Socket. A socket is socket, which is inserted into the processor on the motherboard. The name of the socket on the CPU and motherboard must match.
- Kit. Modern processors can be sold in two trim levels: BOX and TRAY. BOX means that the processor comes with a cooling device (cooler), and TRAY - that only the processor itself is supplied, without a cooling device.
Here is an example of the decoding of the marking of the processor. For example, take Intel Core 2 Duo E8400 3Ghz/6MB/1333MHz S775 BOX.
Processor manufacturer – Intel.
E indicates the type of power consumption. Type E - the standard type of power consumption for desktop PCs (from 55 to 75 W).
The number of cores of the processor is 2 (this is indicated by the name of the Core 2 Duo model).
Processor frequency 3 GHz.
The frequency of the system bus (FSB) is 1333MHz.
The size of the system cache is 6MB.
Set - BOX (there is a cooling device in the kit).
