Arc B580 vs GeForce RTX 3060 Ti

Speed and memory

The Arc B580 and the GeForce RTX 3060 Ti are within a few percent of each other for gaming in our model, so you will not see a difference in play.

The Arc B580 has 12 GB of video memory and the GeForce RTX 3060 Ti has 8 GB. That difference matters at 1440p and in new games at High textures, and it can outweigh a small speed advantage as the card ages.

In our estimates for popular games at 1080p on High, the biggest gap is in Fortnite (300+ against 300+ fps), and the smallest is in ELDEN RING (60 against 60 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.

Power and value

The Arc B580 is rated at 190 W and the GeForce RTX 3060 Ti at 200 W. With a mid-range processor that means a power supply of about 550 W for the first and 550 W for the second. The power draw is close enough that cooling and noise will be similar.

At launch the Arc B580 cost $249 and the GeForce RTX 3060 Ti $399. Per dollar, the Arc B580 gave more performance (13.3 points per $100 against 8.3). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the Arc B580 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 RTX 3060 Ti if the price gap matters more than the small speed difference. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
