GeForce 945M vs Radeon 820M: Pros, Cons & Final Verdict

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

GeForce 945M

2015

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Lower average FPS than Radeon 820M across 31 tracked games in our benchmark data.
  • Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.
  • 2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 150% higher power demand at 75W vs 30W.

Radeon 820M

2024

Why buy it

  • 35.8% more average FPS across 31 tracked games in our benchmark data.
  • 300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).
  • Better long-term bet: RDNA 3+ (2024) on 4nm gives it a newer hardware base for upcoming games.
  • Draws 30W instead of 75W, a 45W reduction.

Trade-offs

  • Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Quick Answers

Which GPU is faster for gaming right now?
Radeon 820M is the faster gaming card right now. In our data, it leads by 35.8% in average FPS across 31 tracked games in our benchmark data and by 1.6% in PassMark G3D (2,143 vs 2,109), 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 512 MB of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 4nm process instead of 28nm, and a newer 2024 generation instead of 2015. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Radeon 820M makes the most sense today based on the pricing and value data we have for this matchup.
