What are measures of CPU performance?

Answer 1

CPU's are measured in MHz or Mega Hertz the larger the # the greater the performance. Some MFG's prefer to use Giga Hertz again it is the same thing just expressed in a different scale. 1.0 GHz = 1000 MHz.

Don't get tricked into something like... buy my 1200 Mhz system it is bigger than his 1.4 Ghz system. it is actually smaller. 1200 < 1400

Good Luck, Hope this helped.

Answer 2

The Clock Speed (Currently measured in GHz), along with operations per cycle are important in determining the performance of a processor.

Cache speed, size, and hit rate are also very important. Integer processing efficiency, pipeline length, pipeline width, bus speed, cycle recovery time, and power / thermal efficiency are all also vital in determining the overall performance of a CPU. Two processors of the same core count and frequency could possibly be extremely different performance wise for all of these reasons.
