Itanium (the 32nm Poulson) in 2012.

The bits and pieces now public and the inherent latency increase
and bandwidth reduction from the Millbrook memory buffer-on-board
architecture (1.066 GHz) seems to suggest that Interlagos will be
15% faster in Integer and 50% to 60% faster in FP applications as a
10 core 2.66 GHz Eagleton with 165W (cpu) +35W (buf) = 200W TDP.
(even without using any AVX)
Without AVX, how can 8 FPUs capable of 4 DP FLOPs be 50% faster than 10 FPUs also capable of 4 DP FLOPs ?
Frequency wise, I do not expect Interlagos to clock faster than 2.5-2.7GHz at 137w.
Secondly, the memory performance of Millbrook is very good considering the extra complexity : Tukwilla does 50GBs in Stream and Beckton does 60GBs+ ( SGI managed 69GBs ) at 4P level.

I wonder what they can (and will) do to please Oracle and IBM in terms
of performance or that they'll try to convert to Patsburg / SandyBridge EX
as fast as they can.

Well Oracle is apparently pleased enough that they dropped the entire AMD based server lineup. I would guess Oracle has been testing Eagleton for quite some time now.
