Yeah, Intel has been on a roll lately, they've managed to hit *most* important schedules.

Nehalem-EX is a little late, but that's not b/c of Intel.

That's what I expect, although I don't know exactly what they are doing in EX5. For some reason, the folks in IBM's PR group ignore me...

My guess is that IBM will include a pretty hefty snoop filter, remote directory and cache for remote data (just like X3)...likely in eDRAM.

I'll be curious to see:
1. How big the local cells are (4 or 8 sockets)
2. How much I/O per local node
3. Whether the remote data cache is still in memory
4. Will it still be limited to 4 cells
5. Bandwidth between EX5 chips
6. Itanium support (just kidding here)

It'll be interesting to see if any of the IPF vendors decide they want to reuse their chipsets for Nehalem-EX though. I would think most of them could come up with a credible Nehalem-EX system...
