GeForce RTX 4080 Super vs Radeon RX 7900 XTX: specs comparison
GeForce RTX 4080 Super came out in 2024 on the Ada Lovelace architecture, Radeon RX 7900 XTX in 2022 on RDNA 3. GeForce RTX 4080 Super has 16 GB of GDDR6X on a 256-bit bus (736 GB/s), Radeon RX 7900 XTX has 24 GB of GDDR6 on a 384-bit bus (960 GB/s). Power draw: 320 W vs 355 W. Recommended PSU: 750 W for GeForce RTX 4080 Super and 800 W for Radeon RX 7900 XTX. 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 4080 Super, Radeon RX 7900 XTX. Higher memory bandwidth: Radeon RX 7900 XTX (960 GB/s)
- 1440pEnough VRAM on both: GeForce RTX 4080 Super, Radeon RX 7900 XTX. Higher memory bandwidth: Radeon RX 7900 XTX (960 GB/s)
- 4KEnough VRAM on both: GeForce RTX 4080 Super, Radeon RX 7900 XTX. Higher memory bandwidth: Radeon RX 7900 XTX (960 GB/s)
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 4080 Super or RX 7900 XTX?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: GeForce RTX 4080 Super, Radeon RX 7900 XTX. Higher memory bandwidth: Radeon RX 7900 XTX (960 GB/s). 1440p: Enough VRAM on both: GeForce RTX 4080 Super, Radeon RX 7900 XTX. Higher memory bandwidth: Radeon RX 7900 XTX (960 GB/s). 4K: Enough VRAM on both: GeForce RTX 4080 Super, Radeon RX 7900 XTX. Higher memory bandwidth: Radeon RX 7900 XTX (960 GB/s). There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RTX 4080 Super and RX 7900 XTX have?
RTX 4080 Super has 16 GB of GDDR6X with 736 GB/s of bandwidth, RX 7900 XTX has 24 GB of GDDR6 and 960 GB/s.
What PSU do RTX 4080 Super and RX 7900 XTX need?
The vendors recommend a 750 W power supply for RTX 4080 Super and 800 W for RX 7900 XTX. Power connectors: RTX 4080 Super — 16-pin (12V-2×6), RX 7900 XTX — 2×8-pin.
Why are the cores of RTX 4080 Super and RX 7900 XTX 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”.
