Buying advice

Which should you buy?

The ROG Astral RTX 5080 OC edges ahead on the Mars Score (78.7 vs 75.1), but the 3.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.

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.

Pick the Radeon RX 9080 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 tdp, ray tracing cores, vram, among others.

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 tells you both are well-rounded; the differences are about trade-offs, not quality.
