NVIDIA Preps GK110-Based GeForce with 2496 CUDA Cores

geforce-gtx-titan-style-5

According to SweClockers, NVIDIA is preparing yet another card based on GK110 silicon. The new card would be a cut-down version of the GeForce GTX Titan, with specifications close to Tesla K20.

NVIDIA GeForce GTX 780?

The new GK110-based card, which name is not yet revealed, would feature 2496 CUDA cores and 320-bit memory interface. In comparison to GTX Titan, the new card would be missing 192 cores and 64-bit interface width. It is believed that the card would feature 3 to 5 GB of GDDR5 memory. Technically this gives two possibilities. SweClockers sources, which are usually quite accurate, may refer to the actual GeForce GTX 780. The card would allegedly arrive in July or August, which suggest these could be the new series. The other possibility is that upcoming GK110-powered model is an another Titan-like graphics card. It’s worth noting that there was a confusion during the launch of the Titan, where many manufacturers would refer to it as a separate series, but others would advertise it as GTX 600 Series card. If Titan is really separate series, then we should see more cards based on it, which is a normal NVIDIA policy. However, the latter possibility seems less reasonable.

The performance gap between the Titan and GeForce GTX 680 isn’t really that big, leaving only small room for the new card. However, it’s big enough to fit a new flagship — GTX 780. Nevertheless, we are still talking about the card with worse specs than Titan, but for a huge price as well.

Anyway, I made this chart to show both possibilities:

GeForce GK110 GTX Titan GTX Titan Lite GeForce GTX 780?
GPU GK110 GK110 GK110
CUDA Cores 2688 2496 2496
Memory Interface 384-bit 320-bit 320-bit
