Radeon RX 7900 XT vs GeForce RTX 4070 Ti Super: specs comparison
Radeon RX 7900 XT came out in 2022 on the RDNA 3 architecture, GeForce RTX 4070 Ti Super in 2024 on Ada Lovelace. Radeon RX 7900 XT has 20 GB of GDDR6 on a 320-bit bus (800 GB/s), GeForce RTX 4070 Ti Super has 16 GB of GDDR6X on a 256-bit bus (672 GB/s). Power draw: 315 W vs 285 W. Recommended PSU: 750 W for Radeon RX 7900 XT and 700 W for GeForce RTX 4070 Ti Super. 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 7900 XT, GeForce RTX 4070 Ti Super. Higher memory bandwidth: Radeon RX 7900 XT (800 GB/s)
- 1440pEnough VRAM on both: Radeon RX 7900 XT, GeForce RTX 4070 Ti Super. Higher memory bandwidth: Radeon RX 7900 XT (800 GB/s)
- 4KEnough VRAM on both: Radeon RX 7900 XT, GeForce RTX 4070 Ti Super. Higher memory bandwidth: Radeon RX 7900 XT (800 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 — RX 7900 XT or RTX 4070 Ti Super?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: Radeon RX 7900 XT, GeForce RTX 4070 Ti Super. Higher memory bandwidth: Radeon RX 7900 XT (800 GB/s). 1440p: Enough VRAM on both: Radeon RX 7900 XT, GeForce RTX 4070 Ti Super. Higher memory bandwidth: Radeon RX 7900 XT (800 GB/s). 4K: Enough VRAM on both: Radeon RX 7900 XT, GeForce RTX 4070 Ti Super. Higher memory bandwidth: Radeon RX 7900 XT (800 GB/s). There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RX 7900 XT and RTX 4070 Ti Super have?
RX 7900 XT has 20 GB of GDDR6 with 800 GB/s of bandwidth, RTX 4070 Ti Super has 16 GB of GDDR6X and 672 GB/s.
What PSU do RX 7900 XT and RTX 4070 Ti Super need?
The vendors recommend a 750 W power supply for RX 7900 XT and 700 W for RTX 4070 Ti Super. Power connectors: RX 7900 XT — 2×8-pin, RTX 4070 Ti Super — 16-pin (12V-2×6).
Why are the cores of RX 7900 XT and RTX 4070 Ti Super 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”.
