The GeForce GTX 780 is all but officially announced. Even though NVIDIA showed the card off at GeForce eSports in China we should expect an official announcement next week on May 23rd. In the meantime it looks like we have some more leaked photos of the card and also the GeForce GTX 770. Both leaked shots are from NVIDIA AIB partner PNY.
PNY GeForce GTX 780
Nothing special here. It looks like PNY will be using the same reference cooler that we have seen on all other shots of the GeForce GTX 780. The GeForce GTX 780 would be based on a cut down version of the GK110 core codenamed “GK110-300-A2″. Unlike the GeForce GTX Titan that has 14 streaming multiprocessors and 2688 cores the GTX 780 will have 12 streaming multiprocessors and 2304 cores. The included 3 GB of GDDR5 memory will operate along a 320/384 bit memory bus. The card is expected to use the same cooler as the one on the GeForce GTX Titan.
PNY GeForce GTX 770
As you can see here the GTX 770, at least PNY’s version will use the same cooler that was found on the GeForce GTX 680. We have seen photos of an NVIDIA GeForce GTX 770 with the same cooler as the Titan though. The GeForce GTX 770 will make use of a refined GK104 core, which has the codename GK10425 A2. It will be clocked a little higher than the original GK104-400 core and will have some minor improvements. It will feature 1536 CUDA cores and 2/4 GB of GDDR5 memory across a 256-bit bus. These are the same specs we saw on the previous generation GeForce GTX 680 card. The expected performance is to be about 5-10% percent faster than the GeForce GTX 680 and will cost around $399-$449.
Check out our graph below that shows the difference between the cards.
