Buying advice

Which should you buy?

These two are nearly even on the Mars Score (62.4 vs 62.5). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Arc B770 if you care most about tdp and boost clock. The biggest gaps in its favor are tdp, boost clock, cuda / stream cores.

Pick the Radeon RX 7800 XT 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 ray tracing cores, 3dmark time spy.

Both ship with comparable vram, memory bus, dlss, so those specs don't 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 tells you both are well-rounded; the differences are about trade-offs, not quality.
