Photos of both of NVIDIA’s upcoming GeForce GTX 770 and GTX 780 have been leaked on the Chiphell Forums. Looking at the leaked photos it looks like NVIDIA will be using the same cooler that was featured on their Titan graphics card. This is the NVTTM cooling design which makes use of a vapor chamber, extended fin cooling and of course much better looks than previous coolers.
While the GeForce GTX 780 will be using the same GK110 core the GeForce GTX 770 will be using a refined version of the GK104 core, which is codenamed GK104-425 A2. It will have some minor improvements over the original GK104 and will also be able to be clocked higher. The GTX 770 will have 1536 CUDA cores and 2GB of GDDR5 running across a 256-bit bus. Here is a run down of expected 700 series cards with the Titan as a reference.
