Overclocking the GeForce GTX 460 graphics cards went extremely well. As shown by the already factory overclocked Palit board, it seems the GF104 chip revision will be friendly to extreme overclockers.
We managed to squeeze a little more out of the Palit GTX 460 Sonic Platinum. The Palit card maxed out at 860MHz for the core and 2020MHz for the memory. The Inno3D version on the other hand reached a core speed of 865MHz while the memory was boosted to 1990MHz.
We had limited time to play with both cards and prepare this review on time, but if you have been wondering all along how will a standard clocked GTX 460 1GB board perform compared to the 768MB variant and to the special Palit version, check out the green translucent boxes below where we depict just that. We underclocked our Palit board to show you a snapshot of the stock GTX 460 1GB performance.
Despite reaching similar frequencies when overclocked the Palit GTX 460 Sonic Platinum (1GB) still has a massive advantage thanks to the wider memory bus. The Palit GTX 460 Sonic Platinum (1GB) saw a 7% performance increase at 1920x1200 while the Inno3D GeForce GTX (768MB) gained 14% more performance.
The Inno3D GeForce GTX (768MB) rendered 7fps more once overclocked allowing it to overtake the stock clocked GTX 460 1GB.
Finally, we tried out these overclocked cards in Modern Warfare 2 and as you can see the Inno3D GeForce GTX (768MB) does very well again as it gains an incredible 26% performance boost. Because the Palit GTX 460 Sonic Platinum (1GB) is already so heavily overclocked from factory we could only squeeze 8% more out of it.
