NVIDIA - GeForce RTX 5080 vs AMD - Radeon RX 7900 XT

The GeForce RTX 5080 edges ahead on the Mars Score (71.4 vs 67.2), but the 4.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.

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, boost clock, among others. The single most decisive one: CUDA / Stream cores — 100.00% more. 10752 vs 5376.

Pick the Radeon RX 7900 XT if you care most about tdp / vram. Its strongest claims are tdp, vram, memory bus. The single most decisive one: TDP — 45.00 W less. 315 vs 360.

Both ship with comparable ray tracing cores, so those specs do not separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
