Nvidia unleashes GeForce GTX 770 graphics card

Nvidia has unveiled its new GTX 770 graphics card. It's the latest Kepler-based graphics card from the Santa Clara-based GPU maker, and it slots in as a high-end enthusiast card right below the GTX 780 and GTX Titan flagship cards.

Of course, no major graphics card launch is complete without mentioning the silicon. The GTX 770 card is based on the same GK104 GPU found in the previous GTX 680 card, but with 2GB or 4GB of faster 256-bit memory. Like the GTX Titan and the GTX 780, the GTX 770 will be dynamically clocked based on the GPU's temperature rather than the GPU's voltage.

GPU Boost 2.0 also governs the cards' cooling fans, so the cards will operate more quietly than competing graphics cards. GTX 770 will come with SLI capabilities, and can use Nvidia's GeForce Experience utilty.

While the GTX 770 is built using the same base chip as the GTX 670, GTX 680, and GTX 690, the GTX 770 comes with faster 7Gbps GDDR5 memory modules. The resultant peak memory bandwidth is 224.3Gbps, 15 per cent more than on the GTX 680. Nvidia claims that this results in a 65 per cent upgrade in performance over a two-year-old GeForce GTX 570 card.

The GeForce GTX 770 is designed for the gamer with a single 1080p display (2GB version) or an ultra HD display (4GB version). Multi-monitor gamers should look at the more robust graphics capabilities of the GTX 690, GTX 780, and GTX Titan graphics cards.
