What are Microprocessor speeds are rated in?

Answer 1

The answer is Mega Hertz. Check it out on the Web : -)

My Two Cents Edit: How do people who give bad answers get trust? Hertz measures the REFRESH RATE OF A PROCESSOR. IPC, MIPS, and MFLOPS measure performance / speed with a great deal of accuracy over clock speed. An intel i7 with all its cores but one disabled will crush a single-core Pentium 4 in tests, even if you set the single-core i7 to 2.0GHz and the Pentium 4 to 4.0GHz

Answer 2

All of the Following

MIPS - Million Instructions Per Second

MFLOPS- Million Floating Point Operations Per Second

IPC - Instructions Per Cycle

These are the most important indications of speed. The last one is

Clock Speed (Measured in GHz). This determines how often commands are carried out on a processor. Keep in mind a super high clock rate on a low IPC processor will typically perform pitifully agianst a low clock rate processor with a humongous IPC. (This is the case in low-end desktop processors vs server processors).
