FirePro W5100 vs Radeon Pro 555X: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

FirePro W5100

2014

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 7.5 vs 0 G3D/$ ($399 MSRP vs Unknown MSRP).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
✅Draws 50W instead of 75W, a 25W reduction.

Trade-offs

❌2014 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon Pro 555X

2018

Why buy it

✅FirePro W5100 is already obsolete for modern gaming, so Radeon Pro 555X is the less risky modern option long term.
✅More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌2018 hardware with 2 GB of VRAM already sits in legacy territory for modern games.
❌Lower G3D Mark per dollar, at 0 vs 7.5 G3D/$ (Unknown MSRP vs $399 MSRP).
❌50% higher power demand at 75W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon Pro 555X is the faster gaming card right now based on the synthetic data we have. It leads by 0.4% in PassMark G3D (3,000 vs 2,987), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon Pro 555X is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 14nm process instead of 28nm, and a newer 2018 generation instead of 2014. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

FirePro W5100 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, FirePro W5100 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon Pro 555X has the stronger long-term case.
