FUD Zilla heard Intel is planning to release 45nm eight-core Nehalem processors in the second half of next year - this chip will most likely be only available for servers.
We also learned that such a chip will be more than twice bigger than the quad core Nehalem and that we should expect TDPs around 150W level. The chip will have much more cache than 8MB that you see on Quad core Nehalem-EX, the server part.
Eight-core Nehalem would definitely have a lot of cache and it will come at significantly lower frequency compared to a highest clocked quad core Bloomfield CPUs. We also learned that such a chip will be announced, used and sell as server / workstation part and that Intel investigates does it makes sense to launch such a chip for desktop market.
