Nvidia delivers a juiced GK104 in the GeForce GTX 770
Today the embargo lifts on the second GeForce GTX 700 series GPU to be announced in a week's time; the Titan-cooled but GK104-powered GeForce GTX 770. Unlike the GTX 780 announced last week, this card does not use the monstrous GK110 GPU, but instead opts for a highly-clocked version of the GK104 chip found previously in the GeForce GTX 680, GTX 670, and GTX 660 Ti. It's the highest clocked-part of all of those cards though, and also has 7Gb/s memory instead of the 6Gb/s variety found in all the previous Kepler cards, giving it a signficant bump in memory bandwidth.
It also features all the cool features we've already covered in our GTX 780 article, including GPU Boost 2.0 and Adaptive Fan Control. If you haven't read that article, go check it out right here. The GTX 770 will also be offered in both 2GB and 4GB flavors, and Nvidia's board partners will be offering boards that are overclocked even more than the Nvidia reference design as well. The GeForce GTX 770 will retail for $400, though versions that are overclocked or have more memory will obviously cost a bit more, but we don't have the exact prices for you as of press time. Watch this space, as we'll add information about the new cards as it comes in today.
GTX 770 specs
Here are the GTX 770's specs. You will note this is the highest-clocked GK104 GPU to roll off the fab yet, and its memory is also the highest clocked that we've ever seen on a GTX board. And with that sweet Titan cooler, not to mention what third-parties can come up with, you can expect even more overclocking and overvolting goodness. The card is the same 10.5-inch length as the GTX 780 and Titan, and also uses one six-pin and one eight-pin PCIe connector, which is two more pins than what is found on the GTX 670.
How Fast is The GTX 770?
We ran all of our tests on our standard GPU test bench, which consists of an Intel Core i7-3960X CPU, 16GB of RAM and an Asus PX79 motherboard, so this system is no slouch. In our tests we saw what we think is the basic argument for the GTX 770, which is you get GTX 680 performance for $400, which is a great deal. Based on the marketing materials we received from Nvidia prior to launch it seems like the company's target for this card was the HD 7970, though we threw the HD 7950 into our chart too since it was the GTX 670's nemesis. Looking at the chart, all three of these cards - the GTX 770, GTX 680, and HD 7970 GHz are damn close to one another, but the rub is that the GTX 770 is the least expensive, and the most silent, of all of them. The HD 7950 is a lot more competitive though, as a quick check on Newegg shows you can get one for around $300 including Tomb Raider, Far Cry 3 Blood Dragon, and Bioshock Infinite. That's a tough deal to pass up, and we think the GTX 770 will be a bit of a tougher sell for Nvidia than the GTX 780 or the Titan, which for now stand alone as the leaders in their price range. Then there's word of some new AMD cards arriving soon so it looks like the $400 price point is about to get real interesting, especially when prices on the GTX 670 and GTX 680 drop now that the GTX 770 has been announced. Will AMD hit back hard, and will we also see a GTX 760 Ti soon? We certainly can't wait to find out.
