As if that weren't fast enough, they say the R600 will have an Overdrive mode similar to the one in current Radeons that will allow users to squeeze a few extra MHz out of the card with AMD's blessing. With overdrive enabled, the R600 will reportedly be able to hit 880MHz core and 1.2-1.3GHz memory speeds. (For reference, Nvidia's GeForce 8800 GTX runs at 575MHz with 900MHz memory, but its 128 stream processors are in a separate clock domain at 1.35GHz.) The Inq says Overdrive will require both 8-pin and 6-pin PCI Express power connectors. Users who "only" plug in two 6-pin connectors will supposedly have to stick with the stock speeds—or find another way to overclock the card.
