The Pascal graphics family continues to grow. After scaling down the Geforce GTX 1050 and GTX 1050 Ti entry-level models, Nvidia is setting its sights on the upper end of the performance scale. The result is the Geforce GTX 1080 Ti, the company’s new top card aimed at gaming enthusiasts.
The model takes place in the same league as Titan X “Pascal”, where both have the graphics circuit GP102 under the shell. For Geforce GTX 1080 Ti, however, it is not just about the reference version Founder’s Edition, but the model opens up in a familiar style to the partner manufacturers’ magic with their own coolers and circuit boards.

In terms of specifications, this is a slightly modified set set against Titan X “Pascal”. The newcomer gets the same 3,584 CUDA cores in the GP102 circuit, but Nvidia chooses to cut into the memory configuration which is scaled down to odd 352 bits and 11 GB of GDDR5X.
Geforce GTX 1080 Ti is compensated with increased clock frequencies for both graphics circuit and GDDR5X. In practice, this means slightly higher computing power for the GPU part and marginally higher memory bandwidth compared to Titan X “Pascal”.
Otherwise, it is a TDP value of 250 watts, as well as extra power supply for Founder’s Edition via 6 + 8-pin PCI Express. Nvidia is also taking the opportunity to plan out the DVI port facing the Titan X “Pascal”, which leaves three Display ports and one HDMI for connecting screens.
Some additional fine grinding is, however, under the shell. Nvidia has redesigned parts of the power supply with a new type of field effect transistors. The result will be increased efficiency compared to both Geforce GTX 980 Ti and GTX 1080.
Another change is the radiator. The design follows the same stealth theme as before, but under the hood, Nvidia has honed the concept. The result should be 5 ° C lower temperature or 2.5 dBA lower sound level at the same power development compared to the Geforce GTX 1080 variant.
According to Nvidia, the Geforce GTX 1080 Ti is 20–40 percent faster than the GTX 1080, depending on the game title and the settings in question. It is between the thumb and forefinger the same performance as the Titan X “Pascal”, which is to be expected with the similar hardware under the shell.
Nvidia believes that the result makes the newcomer the “fastest Ti card” the company has ever launched. The model should on average be about 35 percent quicker than the GTX 1080, which can be compared with 25 and 18 percent for previous generations – GTX 780 to GTX 780 Ti and GTX 980 to GTX 980 Ti.
First out for brave speculators will be the Geforce GTX 1080 Ti Founder’s Edition. The card will be launched next week at a recommended price of 699 dollars, corresponding to approximately 7,900 kronor including VAT.
Models from partner manufacturers will follow later this month. Here, too, Nvidia recommends the price tag of 699 dollars, which, however, can be seen as something of a minimum level. Expensive coolers and other modifications are likely to incur additional costs.
