Cpu Measured In

it depends what you mean by speed?
The number of cycles a CPU has is measured in hz, mhz, ghz etc but this has little influence on performance.
The real measurement of speed is operations per second or million of operations per second (MIPS) on most modern computers.
Older Intel chips ran faster than AMD counterparts yet the AMD chips performed normal tasks much quicker because of the features it had and the way it was made.
Only the newest Intel Core 2 Conroe chips are speed efficient but ever since the AMD Athlon all the way up to the Athlon 64x2, AMD chips have had better performance and were cooler and used less power. This meant smaller fans so quieter too.
To really test the 'speed' of a computer run a program called SuperPi, which calculates Pi to a set number of decimals. It takes between 30 seconds and 3 minutes to calculate PI to 1 million decimals, on machines ranging from a P3 750mhz to an Athlon 64 3000+ (1.8ghz).
I personally pitted a Pentium4 1.7Ghz against an AMD Athlon XP 1700+ (1.5ghz) and gave it different tests. AMD creamed Intel with a heatsink and fan half the size.
Learn more about processors before believing the hype.

All speeds in the CPU are controlled by the CPU clock which runs at a frequency measured in MHz or GHz. The CPU executes what are known as micro operations (UOPs) each requiring one or more clock ticks, but the speed of these cannot be measured.
The lowest level of computer programming uses the complex instruction set defined for the original PC (i386 for 32 bit programs) and later extensions. The speed of executing these can be measured in terms of Millions of Instructions Per Second (MIPS). The other measurement often quoted for scientific applications is Millions of Floating Point Operations Per Second (MFLOPS).
If you want to be totally confused or want to learn about variations, see the following page from my site which provides speed ratings for different types of PC in terms of %MIPS/MHz and %MFLOPS/MHz:

CPU speed is measure in megahertz. A 1GHz CPU can accomplish one million CPU cycles in one second.
Does this mean that a 2GHz CPU is twice as fast as a 1Mhz CPU?
Not necessarily. This depends on how much work each CPU accomplishes in each clock cycle.
The 1GHz CPU might very well be faster, in practice, than the GMhz CPU - if it is more efficient or can process more tasks in each CPU cycle.

measured in GHz. More GHz equals the faster the CPU processing speed.

I think it is measured in Hertz (Hz) which is "cycles per second". Correct me if i'm wrong

the processor is measured in megahertz......... i think.
