GDC 2017 | Nvidia GTX 1080 Ti promises 35 percent performance boost over GTX 1080
We all knew it was coming, but we didn't know it would be this powerful.
The GeForce GTX 1080 Ti will grant gamers the performance level of a Titan X as they will share the same number of streaming multiprocessors (SM), raw transistor count, CUDA cores, and texture mapping units (TMUs). Bus width and render units (ROPs) will be slightly lower on the 1080 Ti, but still greater than on the vanilla GTX 1080. At the end of the day, however, the 1080 Ti is promising 5 percent faster performance in games over the Titan X due to faster memory speed and in spite of the lower bandwidth.
| GeForce GTX 1080 | GeForce GTX 1080 Ti |
|---|---|
| 7.3B transistors | 12B transistors |
| 1.733 GHz Boost | 1.6 GHz Boost |
| 2560:160:64 | 3584:224:88 |
| 256-bit bus width | 352-bit bus width |
| 20 SM count | 28 SM count |
Beyond the core configuration differences, the faster GDDR5X modules from Micron will support improved channel optimizations to reduce noise and jitters. A dualFET bus switch setup should improve power efficiency over the GTX 1080 even further and a brand new cooling solution should result in quieter fan noise of about 2.5 dB when under similar stressful loads.
Nvidia has not yet specified the TDP of the new GPU, but it's expected to be between the GTX 1080 (180 W) and the Titan X (250 W). A slide during the official presentation suggests a TDP of 220 W, though this has not been confirmed. A notebook version of the GPU may be possible on SLI-capable systems like the MSI GT73VR or GT83VR Titan.
Fans of the GTX 1060 and GTX 1080 will see new boards coming from vendors with faster VRAM modules as well. A new variant of the GTX 1060 will be shipping with modules capable of up to 9 Gbps (up from 8 Gbps) while the new GTX 1080 variant will receive the same 11 Gbps modules as the 1080 Ti.
The GTX 1080 Ti Founder's Edition will be available next week for $699 USD and the vanilla GTX 1080 will get a price cut to just $499.
