Radeon RX 6800 vs GeForce RTX 3070: specs comparison
Radeon RX 6800 came out in 2020 on the RDNA 2 architecture, GeForce RTX 3070 in 2020 on Ampere. Radeon RX 6800 has 16 GB of GDDR6 on a 256-bit bus (512 GB/s), GeForce RTX 3070 has 8 GB of GDDR6 on a 256-bit bus (448 GB/s). Power draw: 250 W vs 220 W. Recommended PSU for both: 650 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, GeForce RTX 3070. Higher memory bandwidth: Radeon RX 6800 (512 GB/s)
- 1440pEnough VRAM: Radeon RX 6800
- 4KEnough VRAM: Radeon RX 6800
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.
How to use it
- Compare VRAM and memory bandwidth — they matter most at high resolutions.
- Check TDP, connectors and the recommended PSU: will your power supply cope.
- Look at the “Which is better for 1080p, 1440p and 4K” block.

FAQ
Which is better — RX 6800 or RTX 3070?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: Radeon RX 6800, GeForce RTX 3070. Higher memory bandwidth: Radeon RX 6800 (512 GB/s). 1440p: Enough VRAM: Radeon RX 6800. 4K: Enough VRAM: Radeon RX 6800. There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RX 6800 and RTX 3070 have?
RX 6800 has 16 GB of GDDR6 with 512 GB/s of bandwidth, RTX 3070 has 8 GB of GDDR6 and 448 GB/s.
What PSU do RX 6800 and RTX 3070 need?
The vendors recommend a 650 W power supply for RX 6800 and 650 W for RTX 3070. Power connectors: RX 6800 — 2×8-pin, RTX 3070 — 1×8-pin (FE — 12-pin).
Why are the cores of RX 6800 and RTX 3070 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”.
