Radeon Instinct MI25 MxGPU

2017

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Very weak future-proofing: 2017-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌Lower G3D Mark per dollar, at 0 vs 9.4 G3D/$ (Unknown MSRP vs $450 MSRP).
❌20% higher power demand at 300W vs 250W.

Radeon Ryzen 7 6800U

2020

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 9.4 vs 0 G3D/$ ($450 MSRP vs Unknown MSRP).
✅Less risky long-term buy than Radeon Instinct MI25 MxGPU: it remains the more sensible modern option while Radeon Instinct MI25 MxGPU is already obsolete for modern gaming.
✅Draws 250W instead of 300W, a 50W reduction.

Trade-offs

❌Limited future-proofing: older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.

Quick Answers

So, is Radeon Instinct MI25 MxGPU better than Radeon Ryzen 7 6800U?

Yes. Radeon Instinct MI25 MxGPU is clearly the better overall GPU here. You are also looking at 4,403 vs 4,225 in G3D Mark. On top of that, Radeon Instinct MI25 MxGPU is a 2017 card with FSR upscaling, while Radeon Ryzen 7 6800U is a 2020 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

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

Radeon Ryzen 7 6800U is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2017, 100.0% more ray-tracing hardware, and a 7nm process instead of 14nm. That makes it the safer long-run choice for modern games.

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

Radeon Instinct MI25 MxGPU is the smarter buy by a wide margin. Radeon Instinct MI25 MxGPU is priced in an unclear MSRP range at an unclear MSRP versus $450 MSRP, and you are getting 4.2% higher G3D Mark. Radeon Ryzen 7 6800U really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Radeon Ryzen 7 6800U make more sense than Radeon Instinct MI25 MxGPU?

Yes. Radeon Ryzen 7 6800U 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, lower power draw (250W vs 300W), future-proofing, and staying closer to $450 MSRP more than squeezing out the extra headroom of Radeon Instinct MI25 MxGPU. The trade-off is that Radeon Instinct MI25 MxGPU currently gives you 4.2% higher G3D Mark. Radeon Ryzen 7 6800U still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
