GeForce GTX 275 a Non-Reference Design, Launch Coincides With Radeon HD 4890
With AMD's new graphics card: the Radeon HD 4890 heading towards an April 6~8 worldwide launch, NVIDIA is looking at the situation carefully. While not wanting to spend much into devising a countermeasure, it still wants to address the potential threat Radeon HD 4890 poses. The most recent exposé by Taiwanese website OC Heaven shows there is reason to be optimistic about the performance HD 4890 could end up offering. NVIDIA's counter to it depends on where exactly HD 4890 lands in its competitive positioning against NVIDIA. If it is closer to or better than what the GeForce GTX 285 offers, NVIDIA may bring in price-cuts for the GTX 285, making it more competitive, but if it is poised somewhere between the GTX 260 (216SP) and GTX 285, the new SKU GTX 275 will be brought in.

The new GPU will be specified to have all its 240 stream processors enabled, while having the memory interface GTX 260 comes with: 448-bit GDDR3, with memory configurations of 896 MB or 1792 MB. Furthermore, its development will be care of NVIDIA's partners, who gain license to do so from the company. NVIDIA will not develop a reference design. The launch of the new SKU will coincide with that of the HD 4890, perhaps a few days trailing it.
