[/font]Altogether, for the GTX 690 we’re looking at a pair of fully enabled GK104 GPUs (1536 CUDA cores) clocked at 915MHz, paired with 4GB of 6GHz GDDR5 (2GB per GPU) all on a single card. The GPU boost target will be 1019MHz, though until we have a chance to review the card it’s hard to say what the average clockspeeds will be in most games. Taken altogether, this means the GTX 690 should be able to reach at least 91% of the GTX 680 SLI’s performance and probably closer to 95% depending on where GPU boost tops out.
Meanwhile on the software side the GTX 690 will have an adjustable power target and clock offsets just like the GTX 680. NVIDIA is giving the GTX 690 a max power target of +35%, which given the card’s default power target of 263W means it can be set to draw up to 355W. Until we have a chance to review the card it’s not clear just how many bins higher than the boost clock GPU boost can go, but even if the GTX 690 was unable to quite catch the GTX 680 SLI at standard settings the combination of a higher power target and a core clock offset should be more than enough to make sure it can be overclocked to GTX 680 specs. On paper at least some further overclocking should even be possible, as standard power target for GTX 680 is 170W; so 2x170W for GTX 680 SLI means that all else held equal, there’s still at least 15W of additional headroom to play with.
