While we've already heard plenty about the GTX 770, we've seen few performance numbers. Now though, courtesy of VideoCardz.com, we have some performance slides. Moreover, the folks over at Hermitage Akihabara have also leaked a slide with the card's specifications. The specifications that the slide provides are unsurprising, since we've already seen most of these before.
For starters, the card will feature 1536 CUDA cores, 128 TMUs, 32 ROPs, a base clock speed of 1046 MHz and a boost clock speed of 1085 MHz. Aboard the PCB we'll also find either 2 GB or 4 GB of GDDR5 memory running over a 256-bit memory interface at an effective speed of 7010 MHz. The card will be powered by a combination of an 8-pin and 6-pin PCIe power connectors, have a TDP of 230 W, and a thermal threshold of 95° C. The card remains a GTX 680 in disguise, with a number of goodies added as well as a small overclock.
The most surprising part of the leak though, is that it mentions that the card is expected to retail for around 40,000¥ -- roughly $400.
The performance numbers that were published by VideoCardz.com are shown below. According to the slides, the GTX 770 will outperform the Radeon HD 7970 GHz Edition by about 12.4 percent at 1080p.
