Nvidia Geforce GTX 1080 Ti delivers performance in class with Titan X

It was a packed graphics card summer 2016 from both AMD and Nvidia, which launched their new generations – Polaris and Pascal respectively. However, they are not finished yet. Nvidia is uploading new models in the entry-level segment during the autumn, and next year further news is expected for enthusiasts with well-stocked wallets.

Now the enthusiast site Zol (Chinese) publishes what are said to be specifications for a Geforce GTX 1080 Ti. Like the Titan X flag carrier, the model will be based on the GP102 circuit, but in an even more scaled-down with four inactivated SM clusters instead of two. This gives a total of 3,328 CUDA cores or 30 percent more than GTX 1080 which is built around full-scale GP104.

Despite this, the performance should be similar to the Titan X, as the GTX 1080 Ti is said to compensate with increased clock frequencies. The fundamental frequency is set to 1,503 MHz and boost to 1,623 MHz, which results in the theoretical computing power of the graphics card being only 1.5 percent lower than Titan X.

Although the basic version of the Geforce GTX 1080 Ti is said to be just below the Titan X, it is possible that in many cases it will perform better. However, this presupposes that partner manufacturers are given free rein, something which, in addition to better cooling solutions and circuit boards, is guaranteed to mean increased factory overclocking.

In terms of memory, the GTX 1080 Ti is also expected to be delivered with no less than 12 GB and by all accounts, it will be with the memory type GDDR5X at 10,000 MHz, for a bandwidth of 480 GB / s. However, it is also possible that Nvidia, for cost reasons, chooses to use GDDR5, which in 8,000 MHz would provide 384 GB / s.

Finally, the graphics card’s specified TDP remains at 250 W, which has become something of an upper limit for Nvidia’s top models with a single graphics circuit. In terms of connections, it is probably the same set as previous models, with one DVI, one HDMI and three Displayports.

According to the report, Nvidia plans to launch the Geforce GTX 1080 Ti in January 2017, which means that it will probably see the light of day before AMD takes on the enthusiast segment with the HBM2-equipped architecture Vega.
