Nvidia GK110 To Have 2,880 CUDA Cores
Nvidia has had the performance crown for single GPU graphics cards since the release of the GK104-based GeForce GTX 680, which was initially expected to be based on the non-existent GK100. The PCB layout, low TDP and GK104 moniker (GPUs ending in “4″ have generally been mid range cards, with the GF104 being the GTX 460 and the GF114 being the GTX 560) led us to believe that the GeForce GTX 680 was not to be the top silicon in the Kepler family. That has now been confirmed with both specifications and a die-shot of the GK110 made available earlier today.
First appearing in the upcoming Tesla K20, the GK110 core features a whopping 7.1 billion transistors spread across 15 SMX (streaming multiprocessor) units. Each SMX unit will contain 192 CUDA cores (as with the GK104 before it) which translates to a total of 2880 CUDA cores, or an 87.5 % increase over the GeForce GTX 680. The chip should also have six ROPs, six GDDR5 PHYs for a 384-bit memory bus and a PCI-Express 3.0 interface to the motherboard. Source — Beyond3D Forums
