Temps, overclocking, power-draw

We perform our testing on an open test-bed with a 120mm fan simulating case airflow.

What a difference a die-shrink can make. The 55nm GeForce GTX 295 is significantly cooler under load than a 2GB Radeon HD 4870 X2. Better still, it's a touch cooler than a single-GPU GeForce GTX 280, that new heatsink-and-fan solution is clearly doing the trick.

As mentioned earlier, NVIDIA chose not to bump up the frequencies of the dual-GPU GeForce GTX 295, opting instead to raise the shader-count to GTX 280 levels. Given the efficiency attained from a 55nm shrink, our temperature readings hint at ample overclocking headroom.

With no additional cooling, we managed to raise the default frequencies of 576MHz, 1,242MHz and 1,998MHz - for core, shader and memory, respectively - to a very decent 684MHz, 1,474MHz and 2,400MHz. By doing so, the average framerate at 1,920x1,200 in Enemy Territory: Quake Wars rose from 127.43fps to 131.30fps.

We're certain to see overclocked parts from NVIDIA's various partners in the near future.
