RTX 5080 vs RTX 4080 Super: Gaming Performance & Bottleneck (2026)

Expect a small but real lead for the RTX 5080: 140 FPS at 1440p High against 128 for the RTX 4080 Super with a Ryzen 7 9800X3D, a 10% gap that is about the same at 4K. For a card 1 year newer, that is a modest generational step. The order holds at 1080p (6% apart), so the RTX 5080 is the quicker card at every resolution. With ray tracing on at 1440p they manage 82 and 75 FPS respectively. In esports games like CS2 or Valorant at 1080p they reach 510 and 500 FPS, so either can feed a 360 Hz monitor. At 4K High the RTX 5080 averages 86 FPS and the RTX 4080 Super 78, both playable without upscaling. Both carry 16 GB of VRAM, enough for 4K High. To stay under a 10% CPU bottleneck at 1440p, the RTX 5080 needs a Ryzen 7 5700X3D and the RTX 4080 Super a Core i5-12400F.

Which should you buy?

Buy the RTX 5080 if you want the faster card: it's 10% ahead at 4K. The RTX 4080 Super is the better buy only if it costs at least 10% less, the gap at 1440p, because then it delivers more frames per dollar. Already own the RTX 4080 Super? Going to the RTX 5080 gains 10% at 1440p, which is too small to justify replacing it.

Buy the RTX 5080 if…

  • you want the most FPS: it's 10% faster at 4K and 10% at 1440p.
  • you play with ray tracing: 82 vs 75 FPS at 1440p.
  • you want the newer card (2025) with the longer driver and feature support ahead of it.

Buy the RTX 4080 Super if…

  • your CPU is older: a Core i5-12400F is enough to keep it fed at 1440p.
  • it costs at least 10% less than the RTX 5080, which makes it the better value per frame.

RTX 5080 vs RTX 4080 Super: quick answers

Is the RTX 5080 faster than the RTX 4080 Super?

Yes. The RTX 5080 is about 10% faster at 4K and 10% faster at 1440p in AAA games at High settings. With ray tracing on at 1440p the RTX 5080 gets about 82 FPS and the RTX 4080 Super 75 FPS.

How many FPS do the RTX 5080 and RTX 4080 Super get?

With a Ryzen 7 9800X3D at High settings in AAA games, the RTX 5080 averages about 184 FPS at 1080p, 140 at 1440p and 86 at 4K. The RTX 4080 Super averages 175, 128 and 78 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.

What CPU do I need for the RTX 5080 or RTX 4080 Super?

To keep the CPU bottleneck under 10% at 1440p, the RTX 5080 needs at least a Ryzen 7 5700X3D and the RTX 4080 Super needs at least a Core i5-12400F. 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 5080 and the RTX 4080 Super.
