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

[JumpingJack]

What you said is completely incorrect.

Nehalem's L2 and L3 speeds are comparable to Barcelona.

Also, K10 has the following:

128KB L1 (fast)
512KB L2 (medium)
3MB L3 (slow)

Nehalem has:

64KB L1 (fast)
256KB L2 (medium)
8MB L3 (slow)


Also, I think Shintai owes everyone a lot of money from his 100 euro bet :p

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.
