It's been nearly a month since the GTX 460 stormed into the mainstream graphics market, convincing hardware buffs that Nvidia is still very much alive and kicking, despite a rough start with Fermi. The card originally launched with 768MB or 1GB of GDDR5 VRAM, but vendors are now starting to announce iterations with two gigs of memory. Last week, Gainward revealed a slightly overclocked GTX 460 with 2GB of RAM, and Palit (Gainward's owner) has followed suit with a seemingly identical product.
Besides the extra memory, Palit's GTX 460 Sonic uses the same GF104 GPU and features 336 CUDA cores, a 700MHz core clock, a 1400MHz shader, a memory frequency of 3,600MHz, and a 256-bit memory interface. The card also has a custom cooler and PCB, two-way SLI support, VGA, dual-DVI and HDMI outputs, as well as support for 3D Vision, 3D Vision Surround, DirectCompute, OpenCL, OpenGL 4.0, 32x AA, and of course, DirectX 11. Pricing is rumored to be around 240/$270, which is a reasonable premium on the 1GB models.
