If half of the chip is already on the limit of 300W then all this comparing with 4870/5870 is useless.
LRB with half chip is on par with 4870 perf. wise and on par 5970 (8x 4870) TDP wise.
So when it finally come out it will be say... 10x slower then R900 (very optimistic scenario for Intel) if they cut down power by half and bring 50% speed up in clocks.

As GPU it would bee finally nice to see LRB with TWO DIGITS FPS in any modern game.
Reading comprehension ftw.
On the SGEMM single precision, dense matrix multiply test, Rattner showed Larrabee running at a peak of 417 gigaflops with half of its 80 cores activated; and with all of the cores turned on, it was able to hit 805 gigaflops. As the keynote was winding down, Rattner told the techies to overclock it, and was able to push a single Larrabee chip up to just over 1 teraflops, which is the design goal for the initial Larrabee co-processors.

I'm not really sure that gaming is really what they are swinging at.

Kicking off the SC09 supercomputing event...
