AGhz vs. Ghz

by TimTheToolMan In reply to AGhz vs. Ghz


I think you may be a little confused on the definitions here...

1hz (hertz) = 1 cycle per second
1Ghz (GigaHertz) = 1,000,000,000 cycles per second.

Those roughly translate to instructions per second being processed by the processor with modern piplined processors, but really mean voltage changes from the CPU clock, and when applied across the entire chip, means potential state changes in transistors.

Now for the "A" bit... This is part of the model of the CPU. For example...
The Intel Pentium4 2.0AGHz Processor

Can be broken up...

"Intel Pentium" : Is A Pentium class processor by Intel (which effectively defines the minimum instruction set the processor has)

"4" : of model 4 (which means it has additional instructions and design changes)

"2.0" : Is the Ghz rating

"A" : Is simply an additional model number to distinguish it from the "Pentium4 2.0GHz Processor" and means more design changes, but same clock speed.

Hope that helped,
