This morning, Leadtek has pre-announced Nvidia's GeForce GTX 285 - the 55nm replacement for the GeForce GTX 280 - ahead of its official unveiling next week.
The card, which is based on Nvidia's 55nm GT200b GPU features a 240 stream processors and a 512-bit memory interface backing out onto 1GB of GDDR3 memory.
Leadtek has disclosed core and memory clocks - 648/2,484MHz respectively - but the all important shader clock remains a mystery at the moment. However, doing some quick calculations based on the GeForce GTX 280's clock speeds, we can expect it to hit close to 1,400MHz.
This should give it a reasonable performance improvement over the 65nm GeForce GTX 280 and there should also be some power savings as well.
A pair of GT200b chips are also featured in Nvidia's newly announced GeForce GTX 295
, which took back the performance crown from AMD today in a fairly convincing manner.
In reality, it should perform similarly to BFG Tech's GeForce GTX 280 H2OC
graphics card, but in order to reach those speeds, BFG needed to watercool the 65nm GT200 GPU - we'll be looking at how the GeForce GTX 285 performs in due course.
There's no word on pricing yet, but for now, you can discuss these details in the forums
