Radeon RX 7900 XT vs GeForce RTX 3090 Ti

Speed and memory

The Radeon RX 7900 XT and the GeForce RTX 3090 Ti 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 7900 XT has 20 GB of video memory and the GeForce RTX 3090 Ti has 24 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 (157 against 152 fps), and the smallest is in Call of Duty (145 against 141 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 7900 XT is rated at 315 W and the GeForce RTX 3090 Ti at 450 W. With a mid-range processor that means a power supply of about 750 W for the first and 1000 W for the second. A gap of 135 W shows up in heat and fan noise, and in your electricity use over a few years.

At launch the Radeon RX 7900 XT cost $899 and the GeForce RTX 3090 Ti $1,999. Per dollar, the Radeon RX 7900 XT gave more performance (7.1 points per $100 against 3.1). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the Radeon RX 7900 XT if you want the faster card, and you can accept 20 GB of memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the GeForce RTX 3090 Ti 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.
