so i always hear about how good level 2 cache and more is better and so on...and i've expirenced it too..using powerbooks and imacs that have almost the same insides except the powerbook as more L2 cache... well how important is level 1 cache? theres certainly a lot less of it. 32k/64k on the new G5. is it important? is there a reason there isn't more? what exactly does it do? also just for comparison i checked on the P4's cache..it appears to have 512 like the g4s and g5s but only 8k for L1 cache!! is that a big disadvantage? I'm curious to learn more about all of these processors. and if theres any info you can point to me about the best athlon chips and and itanium and xeon i would appreciate it, info on them is hard to find other than there clock speeds... i like how apple has EVERYTHING about there chips in there tech specs page.
