RX 7800 XT Specs, Gaming FPS, Best CPU and PSU

Quick answer

The RX 7800 XT is a B-tier graphics card in our GPU tier list (gaming score 58, RTX 4090 = 100), built for 1440p gaming. With a fast CPU it averages about 145 FPS at 1080p, 99 FPS at 1440p and 61 FPS at 4K in a typical AAA game at high settings. 16GB of VRAM is enough for ultra textures at 1080p, 1440p and 4K. Its maker recommends a 700W power supply.

RX 7800 XT Gaming Performance (Estimated FPS)

Average FPS from the FPS Calculator’s formula for a typical AAA game, paired with the Ryzen 7 9800X3D so the card is the limit wherever it can be. Figures marked * are held back by the CPU instead. Ray tracing, upscaling and frame generation are not included; they are estimates, not benchmarks.

In the GPU tier list the RX 7800 XT sits in B tier: 1440p gaming at high settings. In games that support it, FSR 3 upscaling and frame generation, plus AFMF in the driver can raise these frame rates, at some cost in image quality or input latency. How upscaling and frame generation work.

Is 16GB of VRAM Enough on the RX 7800 XT?

16GB of VRAM is enough for ultra textures at 1080p, 1440p and 4K. The rule is the GPU VRAM Calculator’s minimum for each resolution and texture level (1080p: 6GB at high, 8GB at ultra; 1440p: 8GB / 10GB; 4K: 12GB / 14GB). Short on VRAM, a game stutters or swaps textures rather than simply losing frames.

Best CPU for the RX 7800 XT

At 1080p, the Core i5-13400F is the most modest current CPU that runs the RX 7800 XT without a noticeable CPU bottleneck (under 15% in our engine, typical AAA game at high settings). At 1440p the card does more of the work, so the Core i3-12100F is already enough. A faster CPU still helps in esports and CPU-heavy games, where the CPU sets the frame rate far more often.

“GPU-limited” is normal and means the card is the part working hardest. A CPU % is how much of the card goes unused. Check any other pair in the PC Bottleneck Calculator.

What PSU Does the RX 7800 XT Need?

The RX 7800 XT’s maker recommends a 700W power supply, and the card itself draws up to about 263W. With a Core i5-13400F, the PSU Calculator estimates a full-load draw of about 492W for the whole PC and recommends a 700W unit (30% headroom, rounded up). A power-hungry CPU such as a Core i9 needs more, so check your exact parts.

Frequently Asked Questions

Is the RX 7800 XT good for 1440p gaming?

Yes. Its gaming score of 58 clears the 1440p line (50) our PC Upgrade Calculator uses, and it averages about 99 FPS at 1440p high in a typical AAA game with a fast CPU.

What CPU should I pair with the RX 7800 XT?

For 1080p, at least a Core i5-13400F to avoid a noticeable CPU bottleneck; at 1440p, a Core i3-12100F is enough. Faster CPUs help in esports and strategy games.

What power supply does the RX 7800 XT need?

Its maker recommends 700W. With a Core i5-13400F our PSU Calculator suggests 700W for the whole PC.

Is 16GB of VRAM enough on the RX 7800 XT?

16GB of VRAM is enough for ultra textures at 1080p, 1440p and 4K.
