How is the speed of current CPUs rated?

Answer 1

CPU's are now are rated in Ghz which means "Billions of Cycles per Second"

Essentially, the more Ghz the processor has, the faster it will execute instructions. Older computers where rated in mhz which is a million cycles per second. For example, a 2.4 ghz processor is the same as 2400 mhz CPU, or a 500 mhz CPU is the same as a .5 ghz CPU. Single core vs. Dual Core vs. quad core ect, A core is what carries out the instructions. two cores doesn't necessarily mean that the processor will have twice the ghz, but twice the power if the program can take advantage of them.

Answer 2

The speed of current CPUs is rated in GHz (gigahertz), which represents the number of clock cycles a CPU can execute per second. A higher GHz rating generally indicates faster processing speed, but it's important to consider other factors like number of cores, cache size, and architecture for a more comprehensive evaluation of CPU performance.
