As soon as Nvidia has announced their latest, Pascal based Titan X, gamer’s were expecting to see a similar performance in a more affordable GTX 1080 Ti. This wait is ending soon, as Nvidia has finally announced the GeForce GTX 1080 Ti, to be released next week.
In terms of specifications, GTX 1080 Ti is very similar to Titan X (Pascal), using the same GP102 GPU. The only sacrifice is the loss of 1 GB VRAM and associated ROPs and L2 cache, thus leaving 1080 Ti with 11 GB VRAM on 352-bit bus, 88 ROP units and 2.8 MB L2 cache. The CUDA core count remains the same at 3584, but the boost clock is a little higher at 1600 MHz. GTX 1080 Ti also uses new faster 11 Gbps GDDR5X chips, thus achieving 484 GB/s bandwidth, slightly over Titan X. Overall, GTX 1080 Ti has 11.5 FLOPS FP32 performance and Nvidia claims that 1080 Ti is more powerful than Titan X as long as you do not need that extra 1 GB of VRAM. We will have to wait till benchmarks to see how noticeable is the difference.
Interestingly, while the latest Titan X is as far as ever from GP100 Tesla cards in compute capability, 1080 Ti does not sacrifice any, compared to Titan X. It has the same INT8 performance geared for neural networks and will actually be slightly faster in most cases. Nvidia has set the recommended price for 1080 Ti at $699. There will be reference Founder’s Editions available as well, but unlike other GTX 10xx cards, they do not differ in the recommended price.
There are also some changes to the GTX 1080 and GTX 1060. The GTX 1080 recommended price is now $499, with no mention of a new FE price, but it is also likely to drop by similar amount. Another change is the availability of higher quality faster GDDR5 and GDDR5X chips to board manufacturers. GTX 1080 originally shipped with 10 Gbps GDDR5X, and GTX 1060 – with 8 Gbps GDDR5. While base specifications will not change, there will be factory overclocked GTX 1080 with 11 Gbps GDDR5X and GTX 1060 with 9 Gbps GDDR5.
