※ 引述《icemilker (icemilker)》之銘言:
: 想找一塊NVIDIA開CUDA來配合COREAVC跟tmpgenc
: 不知道買9800GT GT220或GT240有無差異
: 找不到相關資訊
: 所以請強者幫忙解答一下
: 謝謝
CUDA 1.1 (G8x,G9x)
CUDA 1.2 (GT21x)
CUDA 1.3 (GT200,GT200b)
基本上,1.2/1.3的thread跟register多一倍,而1.2沒有double運算單元,
1.3有.......
不過這和性能無直接對應.對應同一版本的cuda的晶片.
除了因為高低階,TPC/SM/Block數量會不同外.像是GT200的tesla版本的Double
就會比Geforce版本快.
不過就目前來說,不考慮Double運算的情況下,效能原則上還是和TPC/SM/Block/SP
數量成正比
