Which is better for 1080p, 1440p and 4K
- 1080pEnough VRAM on both: GeForce RTX 4070, GeForce RTX 3080 10GB. Higher memory bandwidth: GeForce RTX 3080 10GB (760 GB/s)
- 1440pEnough VRAM: GeForce RTX 4070
- 4KBoth cards have less than 16 GB of VRAM — expect medium settings in new games.
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 RTX 3080 10GB?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: GeForce RTX 4070, GeForce RTX 3080 10GB. Higher memory bandwidth: GeForce RTX 3080 10GB (760 GB/s). 1440p: Enough VRAM: GeForce RTX 4070. 4K: Both cards have less than 16 GB of VRAM — expect medium settings in new games.. There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RTX 4070 and RTX 3080 10GB have?
RTX 4070 has 12 GB of GDDR6X with 504 GB/s of bandwidth, RTX 3080 10GB has 10 GB of GDDR6X and 760 GB/s.
What PSU do RTX 4070 and RTX 3080 10GB need?
The vendors recommend a 650 W power supply for RTX 4070 and 750 W for RTX 3080 10GB. Power connectors: RTX 4070 — 16-pin (12V-2×6), RTX 3080 10GB — 2×8-pin (FE — 12-pin).
Which card is more power-efficient — RTX 4070 or RTX 3080 10GB?
Per the spec sheet, RTX 4070 draws 200 W and RTX 3080 10GB draws 320 W. Lower TDP means easier cooling and a smaller PSU.
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”.
