GeForce RTX 4070 vs Radeon RX 7800 XT: specs comparison
GeForce RTX 4070 came out in 2023 on the Ada Lovelace architecture, Radeon RX 7800 XT in 2023 on RDNA 3. GeForce RTX 4070 has 12 GB of GDDR6X on a 192-bit bus (504 GB/s), Radeon RX 7800 XT has 16 GB of GDDR6 on a 256-bit bus (624 GB/s). Power draw: 200 W vs 263 W. Recommended PSU: 650 W for GeForce RTX 4070 and 700 W for Radeon RX 7800 XT. 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: GeForce RTX 4070, Radeon RX 7800 XT. Higher memory bandwidth: Radeon RX 7800 XT (624 GB/s)
- 1440pEnough VRAM on both: GeForce RTX 4070, Radeon RX 7800 XT. Higher memory bandwidth: Radeon RX 7800 XT (624 GB/s)
- 4KEnough VRAM: Radeon RX 7800 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.
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 — RTX 4070 or RX 7800 XT?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: GeForce RTX 4070, Radeon RX 7800 XT. Higher memory bandwidth: Radeon RX 7800 XT (624 GB/s). 1440p: Enough VRAM on both: GeForce RTX 4070, Radeon RX 7800 XT. Higher memory bandwidth: Radeon RX 7800 XT (624 GB/s). 4K: Enough VRAM: Radeon RX 7800 XT. There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RTX 4070 and RX 7800 XT have?
RTX 4070 has 12 GB of GDDR6X with 504 GB/s of bandwidth, RX 7800 XT has 16 GB of GDDR6 and 624 GB/s.
What PSU do RTX 4070 and RX 7800 XT need?
The vendors recommend a 650 W power supply for RTX 4070 and 700 W for RX 7800 XT. Power connectors: RTX 4070 — 16-pin (12V-2×6), RX 7800 XT — 2×8-pin.
Why are the cores of RTX 4070 and RX 7800 XT 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”.
