Radeon 550X vs Radeon RX Vega 6: Pros, Cons & Final Verdict

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

Radeon 550X

2019

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 13.5 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
✅Radeon RX Vega 6 is already obsolete for modern gaming, so Radeon 550X is the less risky modern option long term.
✅Draws 50W instead of 295W, a 245W reduction.

Trade-offs

❌Lower average FPS than Radeon RX Vega 6 across 50 tracked games in our benchmark data.
❌2019 hardware with 512 MB of VRAM already sits in legacy territory for modern games.

Radeon RX Vega 6

2017

Why buy it

✅92.4% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
❌2017 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 13.5 G3D/$ (Unknown MSRP vs $109 MSRP).
❌490% higher power demand at 295W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX Vega 6 is the faster gaming card right now. In our data, it leads by 92.4% in average FPS across 50 tracked games in our benchmark data and by 1.2% in PassMark G3D (1,492 vs 1,475), so the answer here is pretty clean.

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

Radeon 550X is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB vs Unknown of VRAM and a newer 2019 generation instead of 2017. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon 550X makes the most sense today based on the pricing and value data we have for this matchup. Radeon RX Vega 6 still makes more sense if max raw gaming performance matters more than value.
