Radeon RX 550X vs Radeon RX Vega 11 PRD: 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 RX 550X

2018

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 21.8 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
  • Access to a newer frame-generation stack with FSR Frame Generation (2023).
  • 100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
  • Radeon RX Vega 11 PRD is already obsolete for modern gaming, so Radeon RX 550X is the less risky modern option long term.

Trade-offs

  • Lower average FPS than Radeon RX Vega 11 PRD across 50 tracked games in our benchmark data.
  • 2018 hardware with 4 GB of VRAM already sits in legacy territory for modern games.
  • 233.3% higher power demand at 50W vs 15W.

Radeon RX Vega 11 PRD

2018

Why buy it

  • 4.7% more average FPS across 50 tracked games in our benchmark data.
  • Draws 15W instead of 50W, a 35W reduction.

Trade-offs

  • Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
  • No equivalent frame-generation stack like FSR Frame Generation (2023).
  • 2018 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 21.8 G3D/$ (Unknown MSRP vs $109 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
Radeon RX Vega 11 PRD is the faster gaming card right now. In our data, it leads by 4.7% in average FPS across 50 tracked games in our benchmark data and by 0.9% in PassMark G3D (2,402 vs 2,381), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX 550X is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs Unknown of VRAM and native frame generation with FSR Frame Generation (2023), while Radeon RX Vega 11 PRD has no comparable frame-generation support. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Radeon RX 550X makes the most sense today based on the pricing and value data we have for this matchup. Radeon RX Vega 11 PRD still makes more sense if max raw gaming performance matters more than value.
