Radeon RX 6700 vs Arc B570

Speed and memory

The Radeon RX 6700 and the Arc B570 are within a few percent of each other for gaming in our model, so you will not see a difference in play.

Both cards have 10 GB of video memory, so memory will not separate them.

In our estimates for popular games at 1080p on High, the biggest gap is in Red Dead Redemption 2 (103 against 100 fps), and the smallest is in Cyberpunk 2077 (79 against 77 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.

Power and value

The Radeon RX 6700 is rated at 175 W and the Arc B570 at 150 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 Radeon RX 6700 cost $269 and the Arc B570 $219. Per dollar, the Arc B570 gave more performance (13.2 points per $100 against 11.2). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the Radeon RX 6700 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 Arc B570 if the price gap matters more than the small speed difference, or if you want lower power draw and a quieter PC. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
