that will be used in intel's new multicore cpu and it's based on the classic pentium design. (the one before pentium pro) They plan to use this cpu as a building block for the new generation of intel based videocards too, in groups of 8,16,32,etc. 64 of such cores with 2 threads per core (=128 threads) would only mean 128Watts of power, about as much as a current day 8 core, 128 threads nvidia gf8800 card eats.

I'm struggling to see how they'll use this as the "building block" for a videocard. The reference design here is a general purpose processing unit that would be rather ineffective at doing graphics. GPUs are special purpose and a lot less flexible, generally speaking they're Simple Instruction, Multiple Data processors. While a CPU could do the job of a GPU, it wouldn't do it as efficiently. Similarly a GPU wouldn't have the flexibility to do the work of a CPU.

I have a 2Ghz P4, that doesn't have HT. And yet, It feels like some kind of weird time warp. Why should anyone be excited about HT tech? Really. It was a bad idea when it first came out, its a bad idea now.
