NVIDIA GeForce GTX 285 Unveiled
One short week ago, NVIDIA unveiled the GeForce GTX 295, and with it reclaimed the overall 3D performance crown from a resurgent AMD. As you may know by now, the dual-GPU powered GeForce GTX 295 features a pair of re-worked GT200 GPUs, manufactured using a more advanced 55nm fabrication process than its 65nm predecessor. Looking at the specifications for the individual GPUs used on the GeForce GTX 295, however, revealed something interesting. You see, the GPUs on the GeForce GTX 295 featured a full complement of 240 shader cores, like the former flagship GTX 280, but they had "only" a 448-bit memory interface. The GeForce GTX 280 had a 512-bit interface.
NVIDIA didn't simply lop off a memory partition to create the GPUs for the GTX 295 though. The 55nm GT200B GPUs are fully capable of utilizing a 512-bit interface. NVIDIA chose to implement a 448-bit memory interface per GPU on the GTX 295 to decrease board complexity, and quite frankly because they didn't need to go any wider to have the fastest graphics card on the market. But that meant the GT200B GPU, as it's implemented on the GTX 295, wasn't being used to its fullest potential. This changes today.
Although the GeForce GTX 285 we'll be showing you here hasn't exactly been a well kept secret, its final specifications and performance have been. As its name implies, the GeForce GTX 285 is a step up from the GTX 280. Just how large of a step up remains to be seen, however. Hopefully, we'll be able to find out in the pages ahead as we take the GeForce GTX 285 for a spin through a complete battery of benchmarks, including some numbers from the just-released hot new game title, Mirror's Edge.

Re: NVIDIA GeForce GTX 285 Unveiled
Dear F***** GOD!THe memory clock is more than twice my overclocked maximum!and this monster has 240 processing cores! mine only has 16 it must cost a heck of a bundle right now
