Specs for the next-generation NVIDIA cards have leaked onto the web, but we advise readers not to place too much faith in these specs until the cards actually ship.
On to the specs:
“The GTX 280 enables all features of the D10U processor; the GTX 260 version will consist of a significantly cut-down version of the same GPU. The D10U-30 will enable all 240 unified stream processors designed into the processor. NVIDIA documentation claims these second-generation unified shaders perform 50 percent better than the shaders found on the D9 cards released earlier this year.
The main difference between the two new GeForce GTX variants revolves around the number of shaders and memory bus width. Most importantly, NVIDIA disables 48 stream processors on the GTX 260. GTX 280 ships with a 512-bit memory bus capable of supporting 1GB GDDR3 memory; the GTX 260 alternative has a 448-bit bus with support for 896MB.”
Other rumored specs are that the cards will support PCIe 2.1 and strangely enough they will only support DX 10.0, and not 10.1 or any other revision. This could simply be an early driver issue or perhaps just bogus information. The last interesting feature everyone is buzzing about is PhysX support.
We’re certainly eager to see how well AMD’s Radeon 4000 series stacks up against NVIDIA’s upcoming hardware.
