I found that usually nvidia have less cuda cores than AMD's stream processor

for example 770 and 280x
GTX770 (1536)
r9 280X (2048)

But when it comes to performance usually 770 will outperform 280x slightly...

can anyone tell me why? other factors maybe?

In general both cuda cores and stream processor are the same thing. Those two were the many cores that doing parallel stuff in gpu. (Nvidia also called their cuda cores as stream processor in the past). The difference is both were built on different architecture hence the performance of the two can't be directly compared based on their core count.



different architecture..
nvidia is slightly better for optimize their configuration lead to better perfomance..

and, gamedebate is not reliable..

Hi,

Actually, the situation is different. The r9 280x performs slightly beter than the gtx 770.
Here's some graphs and stuff:

gtx 770 vs r9 280x statistics:http://www.game-debate.com/gpu/index.php?gid=1922&gid2=1774&compare=radeon-r9-280x-directcu-ii-top-3gb-edition-vs-geforce-gtx-770-directcu-ii-2gb-oc-edition

So in short, the r9 280x actually beats the gtx 770 slightly. However, the gtx 770 has slightly beter display than the r9 280x.

Hope this helps^^
