NVIDIA - GeForce RTX 4080 SUPER vs NVIDIA - GeForce RTX 5080

These two are nearly even on the Mars Score (69.7 vs 71.4). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the GeForce RTX 4080 SUPER if you care most about tdp. The biggest gaps in its favor are tdp. The single most decisive one: TDP — 40.00 W less. 320 vs 360.

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. Its strongest claims are 3dmark time spy, cuda / stream cores, ray tracing cores, among others. The single most decisive one: 3DMark Time Spy — 10.70% more. 23800 vs 21500.

Both ship with comparable vram, memory bus, dlss, 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.
