Much like AMD with the Radeon 4890 and specification leaking all the time, it seems to be similar for NVIDIA. As you guys have heard a gazillion times already NVIDIA will release the GeForce GTX 275 as reaction to the new Radeon HD 4890 graphics card.
As it seems the card will have a full set of shader processors accumulating up towards 240, just like the GTX 285. The difference in-between these two needs to be found in the memory bandwidth as the GTX 275 will have a 448-bit memory bus.
It is now rumored that the GTX 275e the following clock frequencies:
- Core clock 633MHz
- Shader clock 1404MHz
- Memory clock 1161MHz (x2)
