Nvidia GTX780 Ti specifications leaked?

Nvidia announced their new high-end Geforce GTX780 Ti during their Montreal, Canada press event on 17 October. The company did not elaborate on specifications, but did note that it was “the fastest Geforce graphics card we’ve ever built.”

Nvidia says they’ll be shipping the GTX780 Ti for consumers and the card will be available to purchase in late November 2013.

In my column about the announcement, I created a table with specifications close to what I thought Nvidia would bring up for the GTX780 Ti. It was based on a whitepaper created by Nvidia detailing their Kepler architecture, which is largely scalable.

Specification	Kepler GK110	Geforce GTX 780 Ti	Geforce GTX Titan	Geforce GTX780
CUDA Cores	2880	2496	2688	2304
Raster Operators	48	48	48	48
Texture units	240	208	224	192
Clock speed	—	902MHz	837MHz	863MHz
Boost speed	—	954MHz	876MHz	900MHz
Memory speed	—	1502MHz	1502MHz	1502MHz
VRAM buffer	6GB	3GB	6GB	3GB
Bus width	384-bit	384-bit	384-bit	384-bit
TDP	250W	250W	250W	220W
Launch price	—	—	$999	$649

New leaks with GPU-Z validations now appear to correlate to my initial expectations as laid out in that table, and I’ve added in new information in bold. The leak appears to be correct in all the details including the driver version, the amount and speed of video memory, and the stock and boost clock speeds look sensible as well.

All things considered, this should be about 15% faster than a GTX780 at a minimum, but only slightly slower than a GTX Titan. Price-wise its anyone’s guess where this will fit, or if Nvidia will price the GTX780 down to combat the AMD Radeon R9 290.

When you take raw compute ability into account, the GTX780 Ti weighs in at just over 4.5TFLOPS of single-precision performance at the stock speed detailed in the screenshot below. That’s slightly faster than a stock GTX Titan (4.49TFLOPS) and quite a bit faster than the stock GTX780 (3.9TFLOPS).
