Radeon RX 6800 XT vs GeForce RTX 3080 10GB: specs comparison

Radeon RX 6800 XT came out in 2020 on the RDNA 2 architecture, GeForce RTX 3080 10GB in 2020 on Ampere. Radeon RX 6800 XT has 16 GB of GDDR6 on a 256-bit bus (512 GB/s), GeForce RTX 3080 10GB has 10 GB of GDDR6X on a 320-bit bus (760 GB/s). Power draw: 300 W vs 320 W. Recommended PSU for both: 750 W. Cores and clocks from different vendors are not directly comparable, so those rows are not highlighted.

In short. The table below is built from the official spec sheets. Green marks the best value in a row, and under the table you will see which resolutions the VRAM is enough for. This is not an FPS benchmark.

Which is better for 1080p, 1440p and 4K

  • 1080pEnough VRAM on both: Radeon RX 6800 XT, GeForce RTX 3080 10GB. Higher memory bandwidth: GeForce RTX 3080 10GB (760 GB/s)
  • 1440pEnough VRAM: Radeon RX 6800 XT
  • 4KEnough VRAM: Radeon RX 6800 XT

Based on actual specs: 8 GB of VRAM or more for 1080p, 12 GB for 1440p and 16 GB for 4K at high settings in new games. This is not an FPS benchmark: we don’t show scores we can’t back with a source.

FAQ

Which is better — RX 6800 XT or RTX 3080 10GB?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: Radeon RX 6800 XT, GeForce RTX 3080 10GB. Higher memory bandwidth: GeForce RTX 3080 10GB (760 GB/s). 1440p: Enough VRAM: Radeon RX 6800 XT. 4K: Enough VRAM: Radeon RX 6800 XT. There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RX 6800 XT and RTX 3080 10GB have?
RX 6800 XT has 16 GB of GDDR6 with 512 GB/s of bandwidth, RTX 3080 10GB has 10 GB of GDDR6X and 760 GB/s.
What PSU do RX 6800 XT and RTX 3080 10GB need?
The vendors recommend a 750 W power supply for RX 6800 XT and 750 W for RTX 3080 10GB. Power connectors: RX 6800 XT — 2×8-pin, RTX 3080 10GB — 2×8-pin (FE — 12-pin).
Why are the cores of RX 6800 XT and RTX 3080 10GB not highlighted?
The “better” highlight on cores and clocks appears only when the cards come from the same vendor and form factor. NVIDIA, AMD and Intel cores are built differently, and laptop GPU clocks depend on the power limit set by the laptop maker.
Can I add a third graphics card?
Yes. Open the interactive comparison — the pair is already selected, you can add two more models and share the link.
Where do the specs come from?
From the official NVIDIA, AMD and Intel spec sheets — each model in the table header links to its vendor page. Bandwidth is calculated as “memory speed × bus width / 8”.
