differences in L2 cache and xxnm

post #1 of 4
Thread Starter 
whats the performance gains between.... 45nm vs 65nm

and

the gains between say... 2M L2 and 6M L2? would i see a huge difference normally?

i do apologize if this is noobish and thank you for your responses and comments.

clock for clock the(6M L2) 45nm chips are usually around 10% faster, than the 65nm (4M L2). The 3M L2 45nm are slightly faster than the 4M 65nm chips clock for clock.

Going from a 2M L2 65nm to a 6M L2 45nm at the same clock speed would probably mean a 15-20% boost in performance, overall. The 45nm chip would likely reach higher clocks aswell.

it depends on the app/game, for some it makes a difference and for some it dont.

if they dont there is no difference at the same speeds but the difference is about 200mhz from 2mb to 4mb and id guess about the same from 4mb to 6mb if they do.

In actual processor power Blameless pretty much hit it head on. But what you actually experience depends on the rest of your hardware and what you use it for.

Say its for games, and say you have an average video card. If you run at low resolutions (1024x768 or lower) you will probably notice a big (10-15% or so) difference between 2M and 6M cache. If you run at higher resolutions, you will gain more from a better video card.
