Arc A770 vs GeForce GTX 1080 Ti

Speed and memory

In our performance index the Arc A770 scores 28 and the GeForce GTX 1080 Ti scores 27, which makes the Arc A770 about 4% faster. That is a small gap, below what most people notice without a frame counter.

The Arc A770 has 16 GB of video memory and the GeForce GTX 1080 Ti has 11 GB. That is a small difference and unlikely to decide anything.

In our estimates for popular games at 1080p on High, the biggest gap is in Cyberpunk 2077 (75 against 72 fps), and the smallest is in Call of Duty (69 against 67 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.

Power and value

The Arc A770 is rated at 225 W and the GeForce GTX 1080 Ti at 250 W. With a mid-range processor that means a power supply of about 650 W for the first and 650 W for the second. The power draw is close enough that cooling and noise will be similar.

At launch the Arc A770 cost $329 and the GeForce GTX 1080 Ti $699. Per dollar, the Arc A770 gave more performance (8.5 points per $100 against 3.9). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the Arc A770 if you want the faster card, and it also has at least as much memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the GeForce GTX 1080 Ti if the price gap matters more than the 4% speed difference. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
