We have already reported that Geforce GTX 275 ends up with a 633MHz core, 1404MHz shader clock and 2268 MHz memory speed. The card uses 448-bit memory interface and GDDR3 memory, so no surprises here.

 
In addition, some partners will release an overclocked version of the card that will work at close to or more than 670MHz, while the shader speed, suggested by Nvidia should stay at 1404MHz and memory can be overclocked to 2350MHz.

We are sure that some of the usual suspects will try to overclock these numbers at least a bit more higher but this is what Nvidia is recommending for the overclocked card.

Geforce GTX 275 should launch this week and if so, it should launch on the April 2nd, while it is also possible to launch in week 15, that starts on April 6.
