GeForce GTX 1080 Ti, Nvidia's fastest Card Yet, Arrives At $699

Nvidia on Tuesday officially unveiled the GeForce GTX 1080 Ti, the company's fastest graphics card that outperforms even the Titan X and costs much less - $699.



The heart of the new video card is the GP102 GPU, with 28 of GP102's 30 SMs enabled. It packs 12 billion transistors and 3,584 CUDA cores - the same as the Titan X Pascal. The difference on the hardware front is that NVIDIA has stripped GP102 of some of its memory/ROP/L2 capacity, which was fully enabled on the Titan. Of the 96 ROPs we get 88; the last ROP block, its memory controller, and 256KB of L2 cache have been disabled.

The new GPU will offer up to 1.6GHz boost clocks and an "OC" clock of 2GHz. However, although we have to do with less enabled functional units clockspeeds for both the core and the memory have been increased. The boost clock of the GTX 1080 Ti is 1582MHz, about 50MHz higher than its Titan counterpart. More significantly, the memory clock on the GTX 1080 Ti is 11Gbps, an increase over the 10Gbps clock found on the Titan and the GTX 1080.

While the GTX 1080 Ti uses more conventional Micron GDDR5X RAM rather than exotic HBM2, which AMD is expected to use in Vega, Nvidia said it can squeeze out almost as much performance from GDDR5X.

According to Nvidia, the GTX 1080 Ti offers just over 11.3 TFLOPS of FP32 performance. This puts the expected shader/texture performance of the card 28% ahead of the current GTX 1080, while the ROP throughput advantage stands 26%, and memory bandwidth at a much greater 51.2%.

Nvidia claims that the new card is roughly 35 percent faster than a standard GTX 1080. The GeForce GTX 980 to GTX 980 Ti was about 25 percent faster, Nvidia said.

Externally the card looks the same as the GeForce GTX 1080, but the company said it redesigned both the cooling solution and power supply for the card. The card is rated at 220W TDP.

The card has not any DVI port. We're looking at 3x DisplayPort 1.4 ports and 1x HDMI 2.0 port. As a consolation to owners who may still be using DVI-based monitors, the company will be including a DisplayPort to DVI adapter with the card.

The GeForce GTX 1080 Ti is expected to go on sale in March. Nvidia's partners will offer a mix of reference and custom designs. The GTX 1080 Ti will initially be offered in a Founder's Edition design, while partners are also bringing up their own semi and fully custom designs to be released later.

Price Cuts For the GeForce GTX 1080

In order to clear the path for the new $699 1080Ti video card, Nvidia is also slashing the price of the GeForce GTX 1080.

The GeForce GTX 1080's MSRP of $600 would leave the card little breathing room with the Ti checking in at $700. So Nvidia CEO Jen-Hsun Huang revealed an official $100 price cut for the GTX 1080, down to $499.

Nvidia also announced that its partners will now have an option to sell GTX 1080 cards with faster memory, as factory overclocked cards.

These GTX 1080 cards will pack GDDR5X memory clocked at 11Gbps, rather than the 10Gbps stock configuration. Factory-overclocked versions of the GeForce GTX 1060 will also be available, clocked at 9Gbps instead of 8Gbps.
