RTX 5090 vs RTX 4090: Gaming Performance & Bottleneck (2026)

With a Ryzen 7 9800X3D at 1440p High, the RTX 5090 averages 183 FPS in AAA games to the RTX 4090's 158. That 16% lead grows to 24% at 4K. For a card 3 years newer, that is a solid generational step. At 1080p the lead shrinks to 3%, because even a 9800X3D can't feed the RTX 5090 fast enough there, so it earns its keep at 1440p and 4K. With ray tracing on at 1440p they manage 115 and 93 FPS respectively. In esports games like CS2 or Valorant at 1080p they reach 519 and 516 FPS, so either can feed a 360 Hz monitor. At 4K High the RTX 5090 averages 120 FPS and the RTX 4090 97, both playable without upscaling. The RTX 5090 also has more memory (32 GB vs 24 GB), though both have enough for 4K High today. To stay under a 10% CPU bottleneck at 1440p, the RTX 5090 needs a Ryzen 7 9800X3D and the RTX 4090 a Core i5-14600K.

Which should you buy?

Buy the RTX 5090 if you want the faster card: it's 24% ahead at 4K. The RTX 4090 is the better buy only if it costs at least 16% less, the gap at 1440p, because then it delivers more frames per dollar. Already own the RTX 4090? Going to the RTX 5090 gains 16% at 1440p, which is a modest upgrade, worth it mainly if you can sell the RTX 4090.

Buy the RTX 5090 if…

  • you want the most FPS: it's 24% faster at 4K and 16% at 1440p.
  • you play with ray tracing: 115 vs 93 FPS at 1440p.
  • you play at 4K or use high-resolution texture packs: 32 GB of VRAM vs 24 GB.
  • you want the newer card (2025) with the longer driver and feature support ahead of it.

Buy the RTX 4090 if…

  • your CPU is older: a Core i5-14600K is enough to keep it fed at 1440p.
  • it costs at least 16% less than the RTX 5090, which makes it the better value per frame.

RTX 5090 vs RTX 4090: quick answers

Is the RTX 5090 faster than the RTX 4090?

Yes. The RTX 5090 is about 24% faster at 4K and 16% faster at 1440p in AAA games at High settings. With ray tracing on at 1440p the RTX 5090 gets about 115 FPS and the RTX 4090 93 FPS.

How many FPS do the RTX 5090 and RTX 4090 get?

With a Ryzen 7 9800X3D at High settings in AAA games, the RTX 5090 averages about 199 FPS at 1080p, 183 at 1440p and 120 at 4K. The RTX 4090 averages 193, 158 and 97 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.

What CPU do I need for the RTX 5090 or RTX 4090?

To keep the CPU bottleneck under 10% at 1440p, the RTX 5090 needs at least a Ryzen 7 9800X3D and the RTX 4090 needs at least a Core i5-14600K. 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 5090 and the RTX 4090.
