Nvidia's GeForce GTX 1070 Ti aims to take down the Radeon Vega 56

From PC World: The rumors were true. Nvidia’s announced the GeForce GTX 1070 Ti on Thursday, a new graphics card designed to snuggle into the spot between the $350 GTX 1070 and $500 GTX 1080 in the GeForce lineup—and one likely released just to claim the performance crown back from AMD’s $400 Radeon Vega 56, which outpunches the GTX 1070 in many games.

The $450 GTX 1070 Ti, which launches November 2, uses the same “GP104” GPU as the GeForce cards it straddles, but it’s a far less cut-down version than the chip in the namesake GTX 1070. In fact, the GTX 1070 Ti hews awfully close to the “full” GP104 GPU in the GTX 1080. Here’s the number of CUDA cores in each graphics card:

GTX 1080: 2,560 CUDA cores
GTX 1070 Ti: 2,432 CUDA cores
GTX 1070: 1,920 CUDA cores
That’s one way to kick dirt in the Vega 56’s face. And it’s not the only one, as you’ll soon see.

The card’s clock speeds swipe elements from both of its cousins, too. The GTX 1070 Ti ships with a 1607MHz base clock and 1683MHz boost clock. By comparison, the GTX 1070 clocks at 1506/1683MHz, and the GTX 1080 hums along at 1607/1733MHz, though in reality Nvidia’s GPU Boost 3 technology typically pushes those cards to higher speeds, especially in customized cards with beefy cooling solutions.

And despite what some wacky early rumors claimed, the GTX 1070 Ti can indeed be overclocked. In fact, Nvidia equipped the card with the same vapor chamber cooling and five-phase dual-FET power design as the GTX 1080 Founders Edition—a step up over the stepped-down capabilities of the baseline GTX 1070 Ti.
