Joe, I completely agree with everything you say, but we're still on separate wavelengths. I'm not sure that Sledgehammer will indeed just be two 64-bit Athlons and a north bridge all packed into one. AMD could do that, especially if they want to take the same design route as the Alpha EV7 (21364). And perhaps AMD's press releases might lead one to believe exactly that.

But that would mean integrating two processor cores, a huge L2 cache (essential for servers), a north bridge, and perhaps a coherency filter (a possibility for NUMA-style architecture) all into one humongous die. It's certainly possible in a 0.13u process, but it's an extremely tall order, even for the bright AMD engineers.

It might make sense just to release the first Sledgehammer w/ x86-64 extensions and LDT. Then worry about integrating the north bridge, a second core, and the kitchen sink later.
