Quick Answers

So, is Radeon HD 7870 XT better than Radeon Instinct MI25 MxGPU?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 4,470 vs 4,403 in G3D Mark. The bigger reason to prefer Radeon HD 7870 XT is the overall package: you are getting FSR upscaling, plus much lower power draw (185W vs 300W).

Which one is more future-proof for 2026 and beyond?

Radeon HD 7870 XT is the safer long-term GPU choice because it gives you the stronger overall hardware and feature outlook for modern games.

Which one is the smarter buy today, not just the cheaper card?

Radeon HD 7870 XT can still make sense if you find it at the right price, especially around $270 MSRP. Radeon HD 7870 XT is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon HD 7870 XT is priced in an unclear MSRP range at $270 MSRP versus an unclear MSRP, and you are getting 1.5% higher G3D Mark. Radeon Instinct MI25 MxGPU is the newer 2017 card, so it still has a real case if you care more about newer architecture than about squeezing out the strongest gaming value today.

When does Radeon Instinct MI25 MxGPU make more sense than Radeon HD 7870 XT?

Yes. Radeon Instinct MI25 MxGPU is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture and staying closer to an unclear MSRP more than squeezing out the extra headroom of Radeon HD 7870 XT. The trade-off is that Radeon HD 7870 XT currently gives you 1.5% higher G3D Mark. It also leads G3D-per-dollar by 100+%.
