FUD Zilla uncovered some information about the Nehalem and Bloomfield processors:
To our surprise the future Nehalem processors with four cores and eight threads will have 8MB of cache memory. Yorkfield has 12MB, or should we say two times 6MB, as this is still a dual chip stitched together. Each core in Yorkfield has 3MB cache and it looks that Nehalem will have 8MB.
We don't know how this new CPU handles the cache, but we guess that Intel couldn't put more cache and the support for multi-thread processing and stay at the reasonable chip size.

Because of two factors, the integrated mem controller will lessen the need for cache, and the controller will take up enough of the die size that the cache had to be given up to keep the chip economical.
