What is the difference between L1, L2 and L3 cache for a CPU?
1 is closer than the other to the CPU so you get a faster transfer
Thanks guys. Didn't know Wiki would have such an extensive work up on this .
I was reading up on my 867 G4 and was looking for the usual L1, L2 cache and found this... "This system has a 256k "on chip" level 2 cache running at processor speed and a 2 MB backside level 3 cache running on a bus one-fourth of the processor speed (217 MHz)."
I was just wondering if this was better or worse than the usual L2 1MB cache found at around the same time as my comp.
The bigger the L(x) capacity is, the better.
