What about 65nm?
This is all very well but what is AMD actually shipping: not 4-core 65nm Barcelona yet for servers, only 2-core, 90nm Rev F Opteron...
AMD's 45nm quad-core processors may not yet be ready to buy, but the chip maker said this week it has working versions in the lab running on test machines.
