It seems that previous rumors from Australia of unbelievable performance of this card are finding their verification. Card which was not revealed by them is quite large (according to the picture), but as they say, this is actually a reference card and non-reference will be tested right after GeForce GTX 670 gets released.
They overclocked this card’s base core clock to 1061 MHz from stock 915 MHz, while boost clock reached a level of 1140 MHz from 994 MHz default. Also the memory wasn’t left intact, but set to 1615 MHz instead (1502 MHz stock).
Here is the conclusion:
NVIDIA GEFORCE GTX 670 overclocking numbers aren’t as impressive as we’d hoped and talking to a couple of partners about these OC results, the numbers seem consistent. What we tend to be hearing is that while getting to GTX 680 speeds aren’t a problem, moving much higher is a little bit of an issue.
Of course clocking the video card at GTX 680 speeds doesn’t mean we’ll get GTX 680 performance due to the reduced CUDA core count on the GTX 670. The slightly higher clocks over the 680 help close the gap, though, and most of the time sees the GTX 670 come out ahead.
As we see companies offer us new coolers and different PCBs over the coming weeks, we might see higher overclocks, but the general word from companies is that the GTX 670 just isn’t a massive overclocking video card. To be honest this doesn’t surprise us all that much as the GTX 680 doesn’t seem to be the biggest overclocking part either (…)
