RTX 4080 Super vs RX 7900 XTX: Gaming Performance & Bottleneck (2026)

There is almost nothing between the RTX 4080 Super and RX 7900 XTX. Paired with a Ryzen 7 9800X3D, our model puts them at 128 vs 131 FPS at 1440p High, and within 2% of each other at 4K. It's a cross-brand matchup: NVIDIA's 2024 card against AMD's 2022 card. At 1080p they're 2% apart too. Ray tracing widens the gap to 39% (75 vs 54 FPS at 1440p), as the RX 7900 XTX's RT hardware is less efficient. In esports games like CS2 or Valorant at 1080p they reach 500 and 503 FPS, so either can feed a 360 Hz monitor. At 4K High the RTX 4080 Super averages 78 FPS and the RX 7900 XTX 80, both playable without upscaling. The RX 7900 XTX also has more memory (24 GB vs 16 GB), though both have enough for 4K High today. With frame rates this close, price and the features you value should decide, not benchmarks. To stay under a 10% CPU bottleneck at 1440p, both need a Core i5-12400F or faster.

Which CPU do you need?

Slowest common CPU that keeps each card under a 10% bottleneck at 1440p High.

Graphics card	Slowest CPU	FPS
RTX 4080 Super	Core i5-12400F	113
RX 7900 XTX	Core i5-12400F	114

Which should you buy?

On raster performance this is a coin toss, so buy whichever is cheaper where you shop. If you play with ray tracing, the RTX 4080 Super is the safer pick (39% faster with RT at 1440p). At the same price, take the RX 7900 XTX for its extra VRAM.

Buy the RTX 4080 Super if…

you play with ray tracing: 75 vs 54 FPS at 1440p.
you want the newer card (2024) with the longer driver and feature support ahead of it.

Buy the RX 7900 XTX if…

you play at 4K or use high-resolution texture packs: 24 GB of VRAM vs 16 GB.
it's the cheaper of the two where you shop: performance is close enough that price decides.

RTX 4080 Super vs RX 7900 XTX: quick answers

Is the RTX 4080 Super faster than the RX 7900 XTX?

They're within 2% of each other at 4K and 2% at 1440p, so in practice they perform the same. With ray tracing on at 1440p the RTX 4080 Super gets about 75 FPS and the RX 7900 XTX 54 FPS.

How many FPS do the RTX 4080 Super and RX 7900 XTX get?

With a Ryzen 7 9800X3D at High settings in AAA games, the RTX 4080 Super averages about 175 FPS at 1080p, 128 at 1440p and 78 at 4K. The RX 7900 XTX averages 177, 131 and 80 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.

What CPU do I need for the RTX 4080 Super or RX 7900 XTX?

To keep the CPU bottleneck under 10% at 1440p, the RTX 4080 Super needs at least a Core i5-12400F and the RX 7900 XTX 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.
