NVIDIA GeForce GTX 780 Ti has 3GB memory and GK110 GPU

Published: 31st Oct 2013, 12:27 GMT


You were probably wondering why I didn’t post anything about the ‘leaked’ GPU-Z screenshots from Chinese forums. Unfortunately these are all fake, so I would only waste my and your time.

Today I have big news for you, some preliminary specs of GeForce GTX 780 TI.

NVIDIA GeForce GTX 780 TI: GK110 + 3GB memory at 7 GHz


GeForce GTX 780 Ti has 2880 CUDA cores, so it’s not a TITAN refresh but a completely new SKU.


So the only thing I cannot confirm yet is the configuration of the GPU. Everything suggests that we are looking at TITAN refresh with slightly faster GPU and much faster memory. There is a slim chance that GTX 780 Ti could be equipped with 2880, especially since the clocks are not much higher than TITAN’s, and I already know that power section had to be redesigned, so the card does require more power (they wouldn’t redesign it for 50MHz right?). Let me also remind you that NVIDIA calls it ‘Newest and Fastest Graphics Card Ever’. So yeah, we can still hope it’s the full GK110.

  • GeForce GTX 780 TI: GK110B P2083 SKU 30 VGA BIOS
  • GeForce GTX TITAN: GK110 P2083 SKU 20 VGA BIOS
  • GeForce GTX 780: GK110 P2083 SKU 10 VGA BIOS

Now let’s look at confirmed specs. The GeForce GTX 780 Ti is clocked at 875 MHz for base and 928 MHz for boost, the memory clock is 1752 MHz (7008 MHz effective). Card is equipped with 3GB memory across 384-bit interface. The GPU itself is Kepler GK110. The revision is B1, most likely GK110-400-B1 (400 if this is a TITAN refresh).

AMD took the crown of performance last week by launching Radeon R9 290X. NVIDIA cards with 384-bit bus look quite poorly compared to 4GB 512-bit card from AMD. Thus, the Green Team decided to pump more power to the memory by installing 7 GHz modules. This way GTX 780 Ti will have 16GB/s higher bandwidth than R9 290X. Is this enough to compete in 4k gaming? Time will tell.

I cannot confirm yet if 3GB memory is the only possible configuration here. I do hope that NVIDIA will also launch 6GB cards, maybe after a while when all TITAN’s are sold out.

While the TITAN was a bridge between GeForce and Quadro cards with much better 64-bit floating point performance (every SMX had 192 FP32 and 64 FP64 CUDA cores) the GTX 780 Ti will feature less FP64 CUDAs. The GTX 780 Ti is definitely more gaming oriented, so it is an obvious and unsurprising move.

NVIDIA GeForce GTX 780 Ti will be released next week, on November 7th for the price of 699 US dollars.
