Intel Details Nehalem uArch Improvements - 256KB L2, 8MB L3 Confirmed

[duploxxx]

We don't know this detail yet.... if Intel does not put the L3 on it's own clock domain, Intel's L3 cache will clock at core frequency ... significantly better than AMD's 1800/2000 Mhz L3. In otherwords, it could be faster or it could be slower... we won't know until we have the CPUs in the wild and people actually measure it.

that was original barcelona L3 speed, by the time you will see nehalem you will also see shangai with several redesigns including this l3 speed and you just have to check the amd forum to see what performance difference this makes on phenom cpu's...
