Processor (cpu) - the Component of the personal computer from which depends productivity of all system as a whole. At purchase processor (cpu) and for the computer it is very important to make a correct choice. Otherwise you can appear in very unpleasant situation when, for example, computing capacity processor (cpu) instead of suffices for your favourite three-dimensional "стрелялки" because of what game obviously "brakes". Further those characteristics processor (cpu) and to which it is necessary to pay the attention at its purchase are listed.
The company - the manufacturer. For today modern processors (cpu) for a platform х86 let out 3 companies: Intel, AMD and VIA Technologies (the basic players of the market are considered Intel and AMD). The market review micro processor (cpu) is presented more low on this page.
Model processor (cpu) and. For computers of initial level (low-end) modern processor (cpu)ми are: VIA C3 (VIA Technologies), Celeron (Intel), Duron (AMD). For high-efficiency systems by the companies are offered processors (cpu): Pentium III/4 (Intel), Athlon (AMD). Detailed characteristics specified processor (cpu) are resulted in a heading "Chronicle of events" (see more low this page).
Updating processor (cpu) and. As a rule, processors (cpu), having the same name, are made in several updatings. So, for example, processor (cpu) Intel Pentium III has three updatings: Katmai, Coppermine and Tualatin. Processors (cpu) Pentium III Tualatin, made on 0,13 - micron technology, are more perfect in comparison with Pentium III Coppermine, issued on 0,18-micron technology. In turn, Pentium III Coppermine is more perfect, than Pentium III Katmai.
Clock frequency. As it is known, clock frequency is that parameter which together with model and updating processor (cpu) and characterizes its speed. Clock frequency modern processor (cpu) and for systems of initial level shouldn't be more low 900-1000 MHz, and for high-efficiency systems it should make nearby 1,5-2 GHz and above.
It is necessary to notice that "high clock frequency" is high efficiency "doesn't mean yet" so. The huge role on productivity is rendered by architecture processor (cpu) and. Than more absolutely architecture, than more than innovative technical decisions it includes, is especially productive itself processor (cpu). So, for example, in productivity processor (cpu) AMD Duron 1,3 GHz in many cases surpasses Intel Celeron 2,0 Ghz. The similar situation is observed and for highly productive chips from two leading manufacturers: processors (cpu) Intel Pentium 4 show the same productivity, as well as processors (cpu) AMD Athlon XP with ready smaller clock frequency. This circumstance has induced Company AMD to mark the processors (cpu) Athlon XP not real, but so-called equivalent frequency (is more detailed about it the market Review see more low this page in a heading ": Intel vs AMD").
Forms-factors. This parameter matters at motherboard purchase under processor (cpu). Naturally, forms-factors processor (cpu) and should coincide with type processors (cpu) a socket on the motherboard. Modern processors (cpu) are issued in the following construction: Socket 370 FC-PGA (Intel Celeron to 1400 MHz, Intel Pentium III, VIA C3), Socket 423 / 478 (Intel Pentium 4, Intel Celeron 1700 MHz and above), Socket A (AMD Athlon / Duron).
It is necessary to notice that forms-factors Socket 370 now already it is considered become outdated, therefore to buy processors (cpu) in such construction (and motherboards with corresponding socket) already hardly costs.
