Nvidia has also announced that they will be giving the GTX 1080 and GTX 1070 price cuts, to $499 and $349 respectively, allowing PC gamers to get some additional value out of their purchases.
The GTX 1080Ti will also contain a new cooling design which will make use of a new vapour chamber plate and a denser aluminium matrix, allowing the GTX 1080Ti to operate both cooler and quieter than the GTX 1080 when using Nvidia’s Founder’s Edition cooler.
Expect performance to land closer to the latter than the former, though. All 28 of the chip’s SMs are turned on, yielding 3584 CUDA cores and 224 texture units at a rated GPU Boost clock rate of 1.6GHz (that’s slightly higher than the Titan X).
The back-end does receive a small haircut: One of its 32-bit memory controllers is disabled, yielding an aggregate 352-bit pathway. This does some funny things to the configurations GeForce GTX 1080 Ti supports, and as a result, the card includes 11GB of memory. Despite the narrower memory path, GeForce GTX 1080 Ti actually offers more theoretical bandwidth than Titan X due to the introduction of 11 Gb/s GDDR5X memory (it moves up to 484 GB/s to the $1200 card’s 480 GB/s).
In introducing GeForce GTX 1080 Ti, Nvidia made a point of discussing the challenges tied to pushing memory to 11 Gb/s. By overcoming them, together with Micron, it created opportunities to offer other SKUs with higher-performance memory. Thus, Nvidia said it plans to sell GP104 GPUs to board partners for GTX 1080 cards with 11 Gb/s GDDR5X and GP106 GPUs for GTX 1060s with 9 Gb/s GDDR5.
