Radeon Pro 555

2017

Why buy it

✅Draws 75W instead of 132W, a 57W reduction.

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 9.2 G3D/$ (Unknown MSRP vs $350 MSRP).

Radeon Ryzen 5 6600U

2021

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 9.2 vs 0 G3D/$ ($350 MSRP vs Unknown MSRP).
✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.
✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.

Quick Answers

So, is Radeon Ryzen 5 6600U better than Radeon Pro 555?

Yes. Radeon Ryzen 5 6600U is clearly the better overall GPU here. You are also looking at 3,206 vs 3,141 in G3D Mark. On top of that, Radeon Ryzen 5 6600U is a 2021 card with FSR upscaling, while Radeon Pro 555 is a 2017 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 5 6600U is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 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 Ryzen 5 6600U can still make sense if you find it at the right price, especially around $350 MSRP. Radeon Ryzen 5 6600U is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon Ryzen 5 6600U is priced in an unclear MSRP range at $350 MSRP versus an unclear MSRP, and you are getting 2.1% higher G3D Mark. Moving to $350 MSRP gets you newer hardware, and FSR upscaling.

Is Radeon Pro 555 still worth buying for gaming in 2026?

Yes. Radeon Pro 555 is still a strong gaming card in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. Price is really the swing factor here. If you find it at or below an unclear MSRP, it remains a very sensible buy. Radeon Ryzen 5 6600U is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR upscaling.
