RTX 3080 vs RX 6800 XT: Gaming Performance & Bottleneck (2026)

The RTX 3080 and RX 6800 XT are effectively tied: at 1440p High they average 88 and 87 FPS in AAA games with a Ryzen 7 9800X3D, and at 4K the gap is just 3%. Both launched in 2020, so this is a straight NVIDIA vs AMD fight for the same buyers. At 1080p they're 2% apart too. Ray tracing widens the gap to 67% (46 vs 28 FPS at 1440p), as the RX 6800 XT's RT hardware is less efficient. In esports games like CS2 or Valorant at 1080p they reach 398 and 392 FPS, so either can feed a 360 Hz monitor. The RX 6800 XT also has more memory (16 GB vs 10 GB), and 10 GB is short of the ~11 GB that 4K High needs. 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 only a Ryzen 5 3600-class CPU.

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 3080	Ryzen 5 3600 or faster	76
RX 6800 XT	Ryzen 5 3600 or faster	76

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 3080 is the safer pick (67% faster with RT at 1440p). At the same price, take the RX 6800 XT for its extra VRAM.

Buy the RTX 3080 if…

you play with ray tracing: 46 vs 28 FPS at 1440p.
it's the cheaper of the two where you shop: performance is close enough that price decides.

Buy the RX 6800 XT if…

you want the most FPS: it's 3% faster at 4K and 2% at 1440p.
you play at 4K or use high-resolution texture packs: 16 GB of VRAM vs 10 GB.

RTX 3080 vs RX 6800 XT: quick answers

Is the RTX 3080 faster than the RX 6800 XT?

They're within 3% of each other at 4K and 2% at 1440p, so in practice they perform the same. With ray tracing on at 1440p the RTX 3080 gets about 46 FPS and the RX 6800 XT 28 FPS.

How many FPS do the RTX 3080 and RX 6800 XT get?

With a Ryzen 7 9800X3D at High settings in AAA games, the RTX 3080 averages about 126 FPS at 1080p, 88 at 1440p and 51 at 4K. The RX 6800 XT averages 124, 87 and 53 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.

What CPU do I need for the RTX 3080 or RX 6800 XT?

To keep the CPU bottleneck under 10% at 1440p, the RTX 3080 needs a Ryzen 5 3600 or faster and the RX 6800 XT 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.
