Processor CPU knowledge

(1) classification of CPU

CPU brand has two big camp, respectively is Intel (Intel) and AMD. these two industry leaders almost monopolized the CPU market, you open the computer look, nothing but Intel and AMD brand (of course, not to exclude very few copycat CPU).Intel's CPUs are divided into Pentium, Celeron and Core.The performance goes from high to low which is Core>Pentium>Celeron.AMD's CPUs are divided into S Demon and Athlon, and the performance of Athlon is certainly superior to Semporn.

②CPU frequency cognition

When we talk about CPUs, we often hear about 2.4GHz, 3.0GHz, etc. What does this mean?These 2.4GHz tokies are the CPU's main frequency, which is the main clock frequency, in MHz.This is used to measure a CPU performance is one of the key indicators.There's another formula for the dominant frequency.The main frequency is equal to the external frequency x the octave coefficient.

Single machine "my computer" → "properties" you can view the CPU type and main frequency size.
