Which one should you buy?
This is the upgrade question for people who own the RTX 3070 8GB: how much faster is a new RTX 5070 12GB, and is it enough to bother? In the Tom's Hardware GPU hierarchy (June 2026), the RTX 3070 8GB averages 58 fps at 1440p and 26 at 4K; the RTX 5070 12GB averages 96 and 54. At 1080p the averages are 87 and 133 fps. That makes the RTX 5070 12GB about 66% faster at 1440p (53% at 1080p, 108% at 4K).
Memory differs: 8GB on the RTX 3070 8GB against 12GB on the RTX 5070 12GB. 8GB cards increasingly need lower texture settings in new games at 1440p, and that won't show up in an average fps number. In games the RTX 3070 8GB draws about 220W and the RTX 5070 12GB about 250W; power supply advice is 650W (maker's advice) vs 650W (maker's advice). The RTX 3070 8GB is about 242mm long, 2 slots thick and uses standard 8-pin power; the RTX 5070 12GB is about 285mm long, 2.5 slots thick with 8-pin or 12V-2x6 depending on the model.
Both use DLSS for upscaling.
Our take: a 66% jump at 1440p is an upgrade you will feel. Check that your power supply and case fit the new card before ordering.
Good to know
- RTX 3070 has 8 GB of video memory, which can force lower texture settings in newer games at 1440p.
