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 P4-2Q

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 2.1 vs 0 G3D/$ ($1,500 MSRP vs Unknown MSRP).

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.
❌200% higher power demand at 225W vs 75W.

Radeon Pro 555

2017

Why buy it

✅Draws 75W instead of 225W, a 150W reduction.
✅More future proof: GCN 4.0 (2016−2020) 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 2.1 G3D/$ (Unknown MSRP vs $1,500 MSRP).

Quick Answers

So, is GRID P4-2Q better than Radeon Pro 555?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 3,162 vs 3,141 in G3D Mark. The bigger reason to prefer GRID P4-2Q is the overall package: you are getting no meaningful modern upscaling stack.

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

GRID P4-2Q 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 P4-2Q can still make sense if you find it at the right price, especially around $1,500 MSRP. GRID P4-2Q is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. GRID P4-2Q is priced in an unclear MSRP range at $1,500 MSRP versus an unclear MSRP, and you are getting 0.7% higher G3D Mark. Radeon Pro 555 is the newer 2017 card, so it still has a real case if you care more about newer architecture and lower power draw (75W vs 225W) than about squeezing out the strongest gaming value today.

When does Radeon Pro 555 make more sense than GRID P4-2Q?

Yes. Radeon Pro 555 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 (75W vs 225W), and staying closer to an unclear MSRP more than squeezing out the extra headroom of GRID P4-2Q. The trade-off is that GRID P4-2Q currently gives you 0.7% higher G3D Mark. It also leads G3D-per-dollar by 100+%.
