GeForce8とRadeonX2000をﾏﾀｰﾘと待つスレ
894 ：Socket774：
>>893 There are quite a few practical possibilites, so lets lay down the speculation:
either nVidia will push mainstream DX10 hardware early for Vista launch and settle for 80nm,
or hold off till late spring/early summer 07 and strive to get 65nm. What special features used
make pretty big difference on power/heat/size/cost/speed etc..(ie low-K interconnect insulation,
high-K gate dielectric, SOI, stress liners etc) Often bigger difference than half-node die shrink.
First and foremost, the priority will be costs, and thus power, so I think nVidia will try to make
as low voltage parts as possible (ie 1.1V-1.2V high end, as as low as 1.0V)
G80 is arranges SP in groups of 16 (8 groups) and 6 ROP each with 64bit memory controller.
8800GTS already gives a clue which direction things are heading (ie disable quads/SP group/ROP
and corresponding memory controller). There are rumours there will be 9-10
products. So, I'm guessing there will (eventually) be 4 product lines.
8900 (direct replacement of 8800, straight die shrink)
8 SP groups, and 6 ROP, 384 bit GGDR4 ($400-$600)
GTX - 700Mhz, with 1.4 Ghz mem (little less total power)
GT - 550Mhz, with 1 Ghz mem (replace 8800GTX)
GS - same as GT but with 1-2 SP groups and 1 ROP disabled, comparable to 8800GTS
8700 6 SP groups, 4 ROP, 256 bit GDDR4 ($200-350)
GT - 700Mhz, 256/512MB 1.4Ghz mem
GS - 550Mhz GT with an SP group disabled.
*highly unlikely, but hoping
8600 4 SP groups, 2 ROP, 128 bit GDDR3 (perhaps even 192 bit? 192MB?) ($100-200)
GT - 700Mhz, 256MB 1.0Ghz mem
GS - 500Mhz, 256MB 0.7Ghz mem
8200 2 SP groups, 2 ROP, 64-128bit GDDR3 ($50-100)
600Mhz with 1.0Ghz mem
400Mhz with 0.7Ghz mem 64bit
(these could just be left over bin from 8600)
there you go 9 products, fiting pretty much every market range...
how good is my guess work.. time will tell!
