RTX 5070 vs RTX 3080: Gaming Performance & Bottleneck (2026)

With a Ryzen 7 9800X3D at 1440p High, the RTX 5070 averages 101 FPS in AAA games to the RTX 3080's 88. That 15% lead grows to 21% at 4K. For a card 5 years newer, that is a solid generational step. The order holds at 1080p (14% apart), so the RTX 5070 is the quicker card at every resolution. Ray tracing widens the gap to 27% (59 vs 46 FPS at 1440p), as the RTX 3080's RT hardware is less efficient. In esports games like CS2 or Valorant at 1080p they reach 445 and 398 FPS, so either can feed a 360 Hz monitor. At 4K the RTX 3080 manages 51 FPS native, and DLSS Quality lifts that to about 73. The RTX 5070 also has more memory (12 GB vs 10 GB), and 10 GB is short of the ~11 GB that 4K High needs. To stay under a 10% CPU bottleneck at 1440p, the RTX 5070 needs a Ryzen 5 5600 and the RTX 3080 a Ryzen 5 3600-class chip.

Which should you buy?

Buy the RTX 5070 if you want the faster card: it's 21% ahead at 4K. The RTX 3080 is the better buy only if it costs at least 15% less, the gap at 1440p, because then it delivers more frames per dollar. Already own the RTX 3080? Going to the RTX 5070 gains 15% at 1440p, which is a modest upgrade, worth it mainly if you can sell the RTX 3080.

Buy the RTX 5070 if…

  • you want the most FPS: it's 21% faster at 4K and 15% at 1440p.
  • you play with ray tracing: 59 vs 46 FPS at 1440p.
  • you play at 4K or use high-resolution texture packs: 12 GB of VRAM vs 10 GB.
  • you want the newer card (2025) with the longer driver and feature support ahead of it.

Buy the RTX 3080 if…

  • your CPU is older: a Ryzen 5 3600-class chip is enough to keep it fed at 1440p.
  • it costs at least 15% less than the RTX 5070, which makes it the better value per frame.

RTX 5070 vs RTX 3080: quick answers

Is the RTX 5070 faster than the RTX 3080?

Yes. The RTX 5070 is about 21% faster at 4K and 15% faster at 1440p in AAA games at High settings. With ray tracing on at 1440p the RTX 5070 gets about 59 FPS and the RTX 3080 46 FPS.

How many FPS do the RTX 5070 and RTX 3080 get?

With a Ryzen 7 9800X3D at High settings in AAA games, the RTX 5070 averages about 144 FPS at 1080p, 101 at 1440p and 61 at 4K. The RTX 3080 averages 126, 88 and 51 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.

What CPU do I need for the RTX 5070 or RTX 3080?

To keep the CPU bottleneck under 10% at 1440p, the RTX 5070 needs at least a Ryzen 5 5600 and the RTX 3080 needs a Ryzen 5 3600 or faster. At 1080p you need a faster CPU for the same result, and at 4K a slower one is fine. A slower CPU narrows the gap between the RTX 5070 and the RTX 3080.
