what does NM mean?

[rlong]

I have been reading about the amd64 130nm and the 90nm.

I'm just wondering what nm means?

nanometer

Transistor size.

 

[rlong]

is the 90 alot better then the 130?

 

[tweebel]

The 90nm is much cooler and has greater overclocking potential.

 

[prolfe]

smaller transistors mean less heat dissipation which generally results in longer CPU life, faster clock speeds, and less power consumption.

 

[Starfishy]

The short answer is "yes" the 90nm is better than the 130nm

Unless you're Intel.

[TechMan]

What he means by "Unless you're Intel" is that Intel's migration from 130nm (Northwood) to 90nm (Prescott) resulted in a cpu producing significantly more heat than its predecessor. Of course, they've increased the number of components in addition to the shrink in transistor size. Theoretically, if it's only a die-shrink, it should have produced a better cpu.

 

[Xeon]

Guess he missed the Pentium M.
