Nvidia Kepler GTX680 vs Radeon HD 7970

Today we have published review of the AMD Radeon HD 7950 graphic cards, Which is a better alternative for GTX 580 at almost the same price. And now it's time for Nvidia to have its own turn. We have got information from our sources that Nvidia's upcoming Kepler GTX680 will be up to 45% faster than AMD's flagship present, the Radeon HD 7970.As price point and specifications of the HD 7970 and HD 7950 are found to be the same as what we have published earlier, this time too, we believe that these specifications, price and release date of Kepler entire series mentioned below will hold true.

But surprisingly reference GTX680 will have just 2 GB frame buffer, even with 1GB lesser than HD 7970, Nvidia GTX680 is able to perform 45% faster. So GTX680 boasts double the amount of stream processors Compared to GTX580. We already know that the entire series Kepler Will Be compliant PCI-E 3.0. For more than a $ 100 HD7970 You Will be getting almost a 45% faster card, now you might have guessed, GTX680 is priced at $ 649 and will be released in April 2012. Entire series is being manufactured on Kepler TSMC's 28nm technology. Another rumor that had spread earlier was that Nvidia will be skipping 600 series and 700 series will use for their Kepler series, but now it's been made clear that, Nvidia is not going to skip GTX600 series. Now you can see the specifications, price point and release date of Nvidia Kepler series GPUs.

Kepler based Nvidia GTX 600 series GPUs - Highlights

Nvidia GTX690 Kepler

750MHz core clock

2 × 4.5GHz 1.75 GB of GDDR5 memory

2 × 1024 Stream Processors

2x448bit Bus Width

Priced at $ 999

Both AMD and Nvidia are following the same trend in Maintaining the order of the series in GPUs. Like HD 7990, GTX 690 has a core clock GTX 680 and lesser than bus width similar to GTX 670th Compared to AMD's HD 7990 price point of $ 849, GTX 690 is priced at $ 999 But comparing the performance to the GTX 690 can offer, HD 7990 is definitely overpriced, and sure AMD has to reduce their prices drastically after the release of kepler GTX 600 series.
