Latest NVidia Kepler Rumors - Specs, Dates and Pricing

Following hot on the heels of the AMD roadmaps revealed at their analyst day last week, Indian website lenzfire.com have published detailed specs for the full range of Kepler GPUs, including prices and projected release dates. As is usual with rumors, the details differ from previous rumors, but they do appear to give a reasonable overview of what to expect.

The source indicates that there are only 3 basic cores, compared to 5 that have been mentioned in previous reports. These cores will be used to produce 7 single-GPU cards and one dual-GPU card.

As there have been suggestions online recently that NVidia or people working in their interest in the Far East are spreading false rumors about the performance expectations of Kepler, I must remind readers that this information is still nothing but rumors. Until we have some concrete information originating from NVidia (I have yet to see a leaked slide that looks like it comes from them) or an OEM we can only speculate. I note also that the source article was published on the same day that AMD had their FAD and announced their upcoming products.

If the above rumors are true, GTX680 will offer approx 45% better performance than AMD Radeon HD7970, which is it's direct competitor. GTX670 will be a 20% improvement over HD7950, while GTX660Ti will perform 10% better than HD7950. GTX660 is said to perform similar to GTX580. GTX650Ti will equal the performance of GTX570, and GTX650 will replace GTX560. Finally, GTX640 will have GTX550Ti performance. This ties in with previous rumors, which have all indicated similar performance expectations.
