Nvidia GT300 yields are under 2%

The translation, as we read it, says there were nine good samples that came back from TSMC from the first hot lot. That is below what several experts told us to expect, but in the ballpark. When we dug further, we got similar numbers, but they were so abysmal that we didn’t believe it. Further digging confirmed the numbers again and again.

….あれ？

「NVIDIAはGT300のEngineering sampleを9月に完成させ、最速で今年の12月に出荷開始とする。」

google翻譯：

「NVIDIA GT300 is an Engineering sample of nine will be completed in January of this year’s fastest 12 to begin shipping in January.」

あー。

well，S|M的Charlie Demerjian 應該是想佐證他的1.7%的數字來源？

不過我很懷疑就是了….XDa

基本上每片晶圓據稱產量有104片，所以大概是500mm^2前後。

如果用兩顆55nm GT200b來推的話也差不多是這個size。

目前據稱core/shader為700/1600，512sp。

不清楚每個TPC構成如何，不過假設512SP正確的話一定不是先前的[3x8sp+2T]x10＝240sp+80TMU就是了，大部分預測是[4x8sp+2T]x16，這樣就是512sp+128TMU。

512bit GDDR5，286.1GB/s，<225w。
