We managed to confirm the full spec of the upcoming Nvidia Geforce GTX 780 graphics card as well as some performance numbers, so we can see how well it measures up to the competition.
Judging by the slides that we saw, the GTX 780, based on Nvidia 28nm GK110 GPU, packs 2304 CUDA cores and works at 863MHz base GPU clock. It feature Nvidia's GPU Boost 2.0 that takes it up to 900MHz for the GPU. It will feature 3GB of GDDR5 memory clocked at 6000MHz and paired up with a 384-bit memory interface. The GTX 780 needs 6+8-pin PCI-Express power connectors and has 250W TDP. It comes with two DL-DVI, HDMI and DisplayPort outputs.
As noted earlier the GTX 780 reference graphics card will use the same cooler previously seen on the GTX Titan that should hold it at somewhere between 40 and 45 dBA making it much less noisy than the GTX 680.
According to an Nvidia-made performance slide that we had a chance to see, which pits the new card to AMD's Radeon HD 7970 GHz Edition, the GTX 780 should end up anywhere between 25 and 50 percent faster than the HD 7970 GHz Edition, with exception of the Tomb Raider where it is faster by around 20 percent.
In any case, we'll know for sure on the 23rd of May, when the GTX 780 is scheduled to launch. The rumored price puts it at anywhere between €500 and €600 but as always, the price is not carved in stone as Nvidia can easily change it.
