GTX/GTS460(GF104) PCB layout and spec leaked(Updated)

[saaya]

original G92 had 112 sps Saaya :P

my bad, typo... already fixed it, but you were faster

i wanted to add a comment about GT200...
i mean its quite interesting to compare GT200 with GT300 (gf100) since they follow the same strategy for all we know...

GT200 (65nm) was hot and had bad yields
gtx280 = 240/240 = 100%
gtx260 = 192/240 = 80%

GF100 (40nm) is hot and has bad yields
GTX480 = 480/512 = 94%
GTX470 = 384/512 = 75%

so far things dont actually look that bad at all, ~5% below what they probably aimed for, at least functional yield wise... clocks and tdp are a different thing...

but now it becomes more interesting...
with gt200 nvidia could shrink the chip to 55nm after only 6 months... which resulted in a boost in functional yields, so much that they upped the sp count of the 260 by 15%!
and upped clocks of the 280 and created a 285, PLUS it brought the tdp down enough to create a dual gpu card...

gt200b (55nm) was still kinda hot but ok and had ok-good yields
gtx295 = +2nd gpu = ~150%
gtx285 = +50mhz = 108%
gtx260 216 = 216/240 = 90%

but nvidia is still stuck with 40nm, and instead of releasing a 470 with more sps, and an updated 480 with more sps and higher clocks, they are releasing a 460/465 with LESS sps.
and if there will be a dual gpu card at all, it will probably take the place of a gtx485 they couldnt reach with a single gpu...

GF104 (40nm) probably still kinda hot but ok and ok-good yields
gtx495 = +2nd gpu = ~110%
gtx46x = 352/512 = 68%

with higher clocks the 46x will probably reach the same level as a 470... but not higher... thats why they end up calling it a 465/460 i guess, and they will probably have a dual gpu card to take the place of a "gtx485"... but other than the 295's 150% of the original gtx280, this dual card will not be notably faster than a 480 i think... at least not on average.
