GeForce RTX 3070 Laptop vs Arc B570

Speed and memory

The GeForce RTX 3070 Laptop 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.

The GeForce RTX 3070 Laptop has 8 GB of video memory and the Arc B570 has 10 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 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 GeForce RTX 3070 Laptop is rated at 140 W and the Arc B570 at 150 W. With a mid-range processor that means a power supply of about 450 W for the first and 550 W for the second. The power draw is close enough that cooling and noise will be similar.

We do not have launch prices for both cards, so we cannot compare value. Check current listings for both.

Which one to buy

Choose the GeForce RTX 3070 Laptop if you want the faster card, and you can accept 8 GB of 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, and you value the extra video memory. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
