SAN FRANCISCO—Nvidia has launched its long-expected GeForce GTX 1080 Ti video card, its follow-up to the GTX 1080 and Titan X Pascal. While the launch wasn’t a surprise thanks to a heap of leaks, its release window and price certainly were: “next week” and $699.
Nvidia claims the GTX 1080 Ti is around 35 percent faster than the GTX 1080, which makes it ever so slightly faster than the £1,100/$1,200 Titan X. That’s not surprising considering the 1080 Ti is, for the most part, identical to the Titan X: they both use the same GP102 GPU, with 3,584 stream processors and 224 texture units split across six graphics processing clusters and 28 SMs.
The key difference, and what gives the 1080 Ti a slight edge over the Titan X, is its memory configuration. The 1080 Ti features a rather odd 11GB of GDDR5X memory, which results in a 352-bit memory interface and 88 ROPs instead of the 12GB of GDDR5X, 384-bit interface, and 96 ROPs of the Titan X.
