Which is better for 1080p, 1440p and 4K

  • 1080pEnough VRAM on both: GeForce RTX 3080 10GB, GeForce RTX 4070 Super. Higher memory bandwidth: GeForce RTX 3080 10GB (760 GB/s)
  • 1440pEnough VRAM: GeForce RTX 4070 Super
  • 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

  1. Compare VRAM and memory bandwidth — they matter most at high resolutions.
  2. Check TDP, connectors and the recommended PSU: will your power supply cope.
  3. Look at the “Which is better for 1080p, 1440p and 4K” block.
  4. To add a third card, press “Change models or add a third”.
