UPDATE: It appears that a number of English speaking sources, including ourselves, have been duped by mistranslation. The above was interpreted as an announcement, while in reality the GTX 780 was merely held up on stage, and nothing more. This was not an official announcement.
The GTX 780 has already been announced in China at the E-Sports festival, a number of days before the official launch in the western world.
The GTX 780's specifications have also surfaced and Hermitage Akihabara have managed to get the official spec sheet. It shows that the card will have 2,304 CUDA cores and a base clock of 863 MHz with a boost clock of 900 MHz. This would create a single precision compute power of 4.0 TFlops. The card's memory would be 3 GB, running over a 384-bit memory interface at a speed of 6.0 GHz. The card would be fed power through a combination of an 8-pin and a 6-pin PCIe Power connector, and have a TDP of 250 W. External display connectivity would be handled by two dual link DVI ports, an HDMI port and a 1.2 DisplayPort.
| GPU | CUDA Cores | TMUs | ROPs | Memory | Memory Bus | Price | |
|---|---|---|---|---|---|---|---|
| GTX 780 | GK110 | 2,304 | 192 | 48 | 3 GB | 384-bit | $599 |
| GTX 770 | GK104-425 | 1,536 | 128 | 32 | 2 GB | 256-bit | $449 |
| GTX 760 Ti | GK104-225 | 1,344 | 112 | 32 | 2 GB | 256-bit | $299 |
So far there has been no word on official pricing, but the prices above are the ones currently being rumored. Take them with a grain of salt. The rumors have shown prices as low as $499 for the GTX 780 and as high as almost GTX Titan level pricing. For now we have to wait a little longer for all the official non-Chinese info.
