G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

GRID P6-4Q

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 2.2 vs 0 G3D/$ ($2,000 MSRP vs Unknown MSRP).
✅Draws 100W instead of 300W, a 200W reduction.

Trade-offs

❌Very weak future-proofing: 2015-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Radeon Instinct MI25 MxGPU

2017

Why buy it

✅More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

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 2.2 G3D/$ (Unknown MSRP vs $2,000 MSRP).
❌200% higher power demand at 300W vs 100W.

Quick Answers

So, is GRID P6-4Q 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 4,429 vs 4,403 in G3D Mark. The bigger reason to prefer GRID P6-4Q is the overall package: you are getting no meaningful modern upscaling stack, plus much lower power draw (100W vs 300W).

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

GRID P6-4Q is the more future-proof choice for 2026 and beyond. You are getting the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

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

GRID P6-4Q can still make sense if you find it at the right price, especially around $2,000 MSRP. GRID P6-4Q is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. GRID P6-4Q is priced in an unclear MSRP range at $2,000 MSRP versus an unclear MSRP, and you are getting 0.6% 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 GRID P6-4Q?

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 GRID P6-4Q. The trade-off is that GRID P6-4Q currently gives you 0.6% higher G3D Mark. It also leads G3D-per-dollar by 100+%.
