Radeon RX 5300 vs Radeon RX 6400

Speed and memory

The Radeon RX 5300 and the Radeon RX 6400 are within a few percent of each other for gaming in our model, so you will not see a difference in play.

The Radeon RX 5300 has 3 GB of video memory and the Radeon RX 6400 has 4 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 (22 against 30 fps), and the smallest is in ELDEN RING (20 against 26 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 5300 is rated at 100 W and the Radeon RX 6400 at 53 W. With a mid-range processor that means a power supply of about 450 W for the first and 450 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 Radeon RX 5300 if you want the faster card, and you can accept 3 GB of memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the Radeon RX 6400 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.
