The reason Intel has been able to keep access times so low for their caches is partly because of the small size. >future and you may get better hardware including faster memory without doing it There will always be better hardware and faster memory. :) >even in case that the size of the L1 goes down because the new L2 may have the >same speed as the old L1. L2 cache on the Pentium 4 at 3GHz takes (if my numbers are correct) something like 6.66ns to access. On the old Pentium 100MHz, the L1 cache, even if were accessed in one clock cycle, would take 10ns. L1 cache on the P4 3GHz takes 0.66ns to access.
