GeForce GTX 1080 Ti Video Card Review

The GeForce GTX 1080 Ti is the a video card from NVIDIA. With 3,584 processing cores and 11 GiB of video RAM, the GeForce GTX 1080 Ti is one of the the highest-end video cards available today. Let’s test it!
The GeForce GTX 1080 Ti is based on the Pascal architecture, which was launched in May 2016, with the GeForce GTX 1080. It uses the GP102 chip, the same used on the Titan X Pascal. Actually, the only differences between the Titan X Pascal and the GeForce GTX 1080 Ti is that the last one comes with one memory chip less, and higher clock rates.
The GeForce GTX 1080 Ti has 3,584 cores running at 1,480 Mhz base clock and 1,582 MHz turbo clock. It has 11 GiB of GDDR5X memory running at 11 GHz, with 352-bit bus, for a bandwidth of 484 GiB/s. Its TDP is 250 W and the minimum power supply is 600 W.
We tested the GeForce GTX 1080 Ti “Founders Edition”, which is the reference model offered by NVIDIA itself. Video card manufacturers like ASUS, Gigabyte, Zotac, Galax, EVGA, etc, can offer custom models. It costs USD 700 for both Founders Edition and custom models.
Just like its less expensive sisters, the GeForce GTX 1080 Ti supports SMP (Simultaneous Multi-Projection) technology, which is useful for Virtual Reality applications, and the Ansel technology, which allows to capture an in-game high-resolution picture with any camera position and even 360 degrees.
The GeForce GTX 1080 Ti supports SLI technology, that combines the processing power of two or more video cards.

AMD offers one video card that costs the same as the GTX 1080 Ti: the Radeon Pro Duo, but we had not access to this card (it is actually very difficult to find). So, we decided to benchmark the GeForce GTX 1080 Ti against the GeForce GTX 1080. We also included the GeForce GTX 1060, to see what is the performance gap between different price categories. So, keep in mind that the cards included in this comparison are not direct competitors to the GTX 1080 Ti.
In the table below, we compare the main specs from the video cards we included in this review. Prices were researched at Newegg.com for this article.

The GeForce GTX 1080 Ti “Founders Edition” looks exactly like the GTX 1080, being 10.6 inches (268 mm) long and using two slots. It uses a centrifugal fan, which is a good choice because it pushed the hot air outside the case, and allow you to use the contiguous slot to the video card.
Figure 2 shows the video connectors of the GeForce GTX 1080 Ti FE. It brings three DisplayPort 1.4 and one HDMI 2.0b connectors.

[nextpage title=”Conclusions”]
When we tested the GeForce GTX 1080, we concluded it has plenty of power to run the most recent and demanding games, with 4K resolution and high quality.
Now that NVIDIA launched a higher-end video card, we can say NVIDIA offers even more performance. Actually, the GeForce GTX 1080 Ti offers around 30% more performance than the GTX 1080, which is a substantial advance over a video card that was already very powerful. So, if you want spare of power to run games in 4K resoltion and maximum quality, the GeForce GTX 1080 Ti is the natural choice. That’s why we gave it our Golden Award.
Its only drawback is, of course, its price. Its is good to keep in mind that, if you have a Full HD display, the GTX 1080 Ti is simply too much, since even a mainstream video card like the GeForce GTX 1060 does the job. So, buying a GeForce GTX 1080 Ti only makes sense if you have a high-resolution display.
