Radeon 820M vs Radeon RX Vega 11 Ryzen 5 3400G: 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 820M

2024

Why buy it

  • 100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
  • Better long-term bet: RDNA 3+ (2024) on 4nm gives it a newer hardware base for upcoming games.
  • More future proof: RDNA 3+ (2024) on 4nm with a newer platform for upcoming games.

Trade-offs

  • Lower average FPS than Radeon RX Vega 11 Ryzen 5 3400G across 31 tracked games in our benchmark data.
  • 100% higher power demand at 30W vs 15W.

Radeon RX Vega 11 Ryzen 5 3400G

2020

Why buy it

  • 1.5% more average FPS across 31 tracked games in our benchmark data.
  • Draws 15W instead of 30W, a 15W reduction.

Trade-offs

  • Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
  • 2020 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?
Radeon RX Vega 11 Ryzen 5 3400G is the faster gaming card right now. In our data, it leads by 1.5% in average FPS across 31 tracked games in our benchmark data and by 0.1% in PassMark G3D (2,145 vs 2,143), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon 820M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM, a 4nm process instead of 7nm, and a newer 2024 generation instead of 2020. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Radeon RX Vega 11 Ryzen 5 3400G makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, Radeon RX Vega 11 Ryzen 5 3400G is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 820M has the stronger long-term case.
