*whistles*. http://www.hotchips.org/uploads/archive22/HC22.24.630-1-Hu-GS464V-godson.pdf yyyeeee godds. wow. yeah i missed that in the first cursory glance, i didn't realise i'd downloaded that pdf already. i should pay more attention :) single core. 1ghz 1080p. wow. crucial question of course: if the 2G is 3 watts in 65nm @ 1ghz, and has a 64-bit FP unit, what's the 2H going to be like in 28nm @ 1ghz, with a 256-bit SIMD and all the other extensions that make it ROCK! :) 65nm down to 28nm, it's a straight jump to 1/4 of 3 watts - 0.75 watts, then - but all the extra stuff... did someone say that the 16- core version, 28nm, 1ghz, would still be only around 15 watts? that'd make a single-core roughly... yeah, just under 1 watt which would be ... well... damn good would be an understatement. l. -- You received this message because you are subscribed to the Google Groups "loongson-dev" group.
