In addition to the GK110 based Nvidia Geforce GTX 780, we managed to get some details regarding the GK104-based GTX 770 as well. Scheduled to be officially launched a week after the GTX 780, on May 30th, the GTX 770 will aim a similar price point as the Radeon HD 7970 GHz Edition but will end up to be at least a bit faster.
As noted and rumored earlier, the GTX 770 will be a simple rebrand of the GTX 680, but with slightly higher clocks. It features 1536 CUDA cores and runs at 1046MHz base GPU clock. It also feature Nvidia GPU Boost 2.0 that will take the GPU up to 1085MHz when possible. It will be available with both 2GB and 4GB of memory, clocked at a pretty impressive 7000MHz and paired up with a 256-bit memory interface.
As it is based on a version of the GK104 chip it is no wonder that it needs 6+8-pin PCI-Express power connectors and has a 230W TDP. It will also feature two DL-DVI, HDMI and DisplayPort outputs. Judging by earlier leaks, pictures and some information that we saw, it will also use a reference cooler similar or same as the one on the GTX Titan. This means that the card will be significantly quiter.
Judging by the slides, it should end up anywhere between 10 and 20 percent faster than the HD 7970 GHz Edition and in some cases, like Tomb Raider, Crysis 3 and Max Payne 3, on par or just a tad bit faster.
Of course, we will not talk about the price as Nvidia can easily change it a day before the launch, but it is expected to be somewhere around the HD 7970 GHz Edition, or in the €400-450/US $450+ range.
