Meet the Pascal family: Nvidia reportedly working on GP102-based GTX Titan and GTX 1080 TiBy Tim Schiesser 50 comments
Even though we've only just seen the launch of Nvidia's GeForce GTX 1080, new rumors have started to appear that detail two faster graphics cards based on upcoming Pascal GP102 silicon: a new GeForce GTX Titan, and a GeForce GTX 1080 Ti.
A report from ChipHell, via The Tech Report, has allegedly detailed these two new graphics cards along with a more modest GTX 1060. The specification table they posted, seen below, includes some interesting tidbits if they turn out to be accurate.
A fully unlocked version of GP102 appears to be included with the Titan, packing 3,840 CUDA cores, up from 2,560 in the GTX 1080. This is even more CUDA cores than the GP100-based Tesla P100 (which has 3,584 cores), although GP102 seems to be limited to 1/32 FP64 performance rather than the 1/2 seen in the P100.
The GTX 1080 Ti would see the CUDA core count cut to 3,456 along with a reduction in TMUs. Both the 1080 Ti and Titan are listed as having the same clock speeds and memory systems (GDDR5X), along with the same TDP of 250W, although for high-compute environments, the Titan packs a huge 24 GB of VRAM as opposed to the 1080 Ti's 12 GB.
As for the GTX 1060, ChipHell has this card listed as using an even further cut down variant of GP104 with just 1,280 CUDA cores. For reference, the fully unlocked GP104 used in the GTX 1080 has 2,560 cores, while the cut down variant in the GTX 1070 features 1,920.
The GTX 1060 is also listed has having slightly lower clock speeds and reduced memory bandwidth, along with a lower TDP of just 110W.
At this early stage it's not clear whether these specifications will turn out to be true. Nvidia hasn't even released the GTX 1070 yet, so it'll be a while before we hear any details on the GTX 1080 Ti or new GTX Titan.
