Intel's 32nm Update: The Follow-on to Core i7 and More

The Server Roadmap
Intel’s 32nm server roadmap is notably different from the desktop roadmap. Nehalem-EX will ship into the Xeon 7000 series as an 8-core, 16-thread part. It will eventually get replaced sometime in 2010 with a 32nm Westmere derivative.
We’ll see a 32nm six-core Westmere based processor in the Xeon 5000 series in 2010.
Finally Lynnfield and Clarkdale will be carried over to the entry level Xeon platforms at the end of this year and into 2010.
What About Chipsets?
Intel’s X58 chipset will remain the top dog through 2010. Chances are that we won’t see it replaced until the next tock with Sandy Bridge. Now that isn’t to say that the six-core 32nm Gulftown will work in existing X58 motherboards; while that would be nice, Intel does have a habit of forcing motherboard upgrades, we’ll have to wait and see.
The rest of the Nehalem/Westmere family will rely on Intel’s upcoming P55 chipset:
Originally both Lynnfield and Havendale were to have an on-package PCIe controller, I’m not sure if that has changed with the Havendale cancellation but I see no reason for it to have. In which case a Lynnfield system will still look like this:

For the CPU market, the problem is the ever growing amount of cache memory. Intel processors are designed with the large cache being their solution to improvements that AMD brings to the table.I suspect that Intel will have more trouble after this move to the new fab process because the difficulty in moving to a new process node grows at an exponential rate. We saw Intel hit a wall with the Pentium 3 line because they were not ready for a new process shrink at that point, so the P4 came out. When Intel got their process technology on track, the people at Intel could go back to the Pentium 3 design(with improvements) to release the Core and Core 2 Duo.
There will come a time when an all new design will be needed in order to hold on to their lead, and that is when AMD will probably catch back up, if AMD can survive until then.

What an utter load of BS. Thanks fanboy.You get all that from wiki?

Even though my last three CPUs were all from AMD (they made sense at the time- K6-III/400, Athlon XP 1700+, Athlon 64 X2 4400+), I have to disagree with your comment about the improvements (presumably the integrated memory controller) which AMD brings to the table.With Core i7, Intel has effectively removed the one last technological advantage AMD had- faster memory access. The fact that Intel chips still tend to have larger L3 caches is quite simply because they can afford to give it to them, as they are ahead of AMD on the fab-process. For a high-end desktop chip where there is die-space to spare, you could add some more cores which will probably sit idle (keeping four busy is hard enough, especially with HT), but adding more L3 cache (so long as the latency of it is not adversely affected) is a very cheap and easy way to use up the space and provide a bit of a speedup in almost everything.
AMD is currently fighting a losing game. The Phenom II (bug-fixed Phenom) cannot compete with Core i7 with AMDs current fabs, and unlike Intel who have the tick-tock steady new-process, then new-design with large teams working on each step; AMD seem to have one team working on a new design, which has to be made to work with whichever process looks like the best option at the time.
We need AMD to survive for the x86 (or x64, who came up with that :p ) CPU market to be competitive, but I think the head of AMD is going to have to get into bed with the head of IBM, else they are doomed to fall ever further behind Intel in chip-design. The K10 is promising, but a long way off still, and AMD hasn't exactly been raking in the billions of dollars of profits recently to do that R&D. VIA have found an x86 CPU niche they can compete in, I fear that unless AMD pull an elephant out the hat with the K10, they'll have to slot in between VIA and Intel in providing CPUs specialising in a particular performance-sector, with Intel being the undisputed leader.

Well said. I concur.
