Radeon R5 M420 vs Radeon Vega 2: 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 R5 M420

2016

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 1.7 vs 0 G3D/$ ($300 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).

Trade-offs

  • Lower average FPS than Radeon Vega 2 across 50 tracked games in our benchmark data.
  • 2016 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 400% higher power demand at 75W vs 15W.

Radeon Vega 2

2021

Why buy it

  • 12.2% more average FPS across 50 tracked games in our benchmark data.
  • Radeon R5 M420 is already obsolete for modern gaming, so Radeon Vega 2 is the less risky modern option long term.
  • Draws 15W instead of 75W, a 60W reduction.

Trade-offs

  • Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
  • 2021 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 1.7 G3D/$ (Unknown MSRP vs $300 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
Radeon Vega 2 is the faster gaming card right now. In our data, it leads by 12.2% in average FPS across 50 tracked games in our benchmark data and by 0.4% in PassMark G3D (506 vs 504), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon Vega 2 is the safer long-term pick for 2026 and beyond. The case is simple: a 7nm process instead of 28nm and a newer 2021 generation instead of 2016. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon R5 M420 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, Radeon R5 M420 is the easier value choice. If you care more about 1080p headroom, Radeon Vega 2 has the stronger long-term case.
