Between the GeForce RTX 5080 and Radeon RX 7800 XT, the GeForce RTX 5080 comes out ahead in cuda / stream cores and 3dmark time spy, while the Radeon RX 7800 XT wins on tdp. Overall, the GeForce RTX 5080 scores 71.9 and the Radeon RX 7800 XT scores 62.5 on our Mars Score.
Which should you buy?
The GeForce RTX 5080 is the clear pick on raw spec strength, leading by 9.4 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the GeForce RTX 5080 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are cuda / stream cores, 3dmark time spy, ray tracing cores, among others.
Pick the Radeon RX 7800 XT if you care most about tdp. Its strongest claims are tdp.
Both ship with comparable vram, memory bus, so those specs don't separate the two — focus on the differences below.
Bottom line: the GeForce RTX 5080 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
