ASUS - ROG Astral RTX 5080 OC vs AMD - Radeon RX 9080 XT

These two are nearly even on the Mars Score (77.5 vs 79). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.

Pick the ROG Astral RTX 5080 OC 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, dlss. The single most decisive one: CUDA / Stream cores — 31.25% more. 10752 vs 8192.

Pick the Radeon RX 9080 XT if you care most about ray tracing cores / vram. Its strongest claims are ray tracing cores, vram, memory bus, among others. The single most decisive one: Ray tracing cores — 52.38% more. 128 vs 84.

There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.

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.
