Combjelly, Re: "it is very likely that a SledgeHammer in 90nm would be closer to 100mm^2 than 150mm^2..."

Maybe not. My WAG for Sledghammer die size is ~130mm^2. I think the 512KB of L2 will add about 15mm^2 to the die, and the other two HT links will add 5mm^2 each. Given that the Clawhammer is already 104mm^2, that would put Sledgehammer at about 130mm^2.

I base this on the projection for the Thoroughbred die size, and the difference between it and Clawhammer. An 80mm^2 TBred subtracted from a 104mm^2 Clawhammer leaves 24mm^2. I believe it adds up like this: 4mm^2 for x86-64, 8mm^2 for 256KB extra cache, 8mm^2 for on-die memory controller, and 4mm^2 for micro-architectural changes such as deeper buffers, larger BHT, TLB, OOO queues, etc.
