Radeon HD 8790M vs Radeon 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 HD 8790M

2013

Why buy it

  • 100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).

Trade-offs

  • Lower average FPS than Radeon Vega 6 across 50 tracked games in our benchmark data.
  • 2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon Vega 6

2021

Why buy it

  • 52.0% more average FPS across 50 tracked games in our benchmark data.
  • Radeon HD 8790M is already obsolete for modern gaming, so Radeon Vega 6 is the less risky modern option long term.
  • More future proof: GCN 5.1 (2018−2022) on 7nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with Unknown vs 2 GB 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.

Quick Answers

Which GPU is faster for gaming right now?
Radeon Vega 6 is the faster gaming card right now. In our data, it leads by 52.0% in average FPS across 50 tracked games in our benchmark data and by 0.2% in PassMark G3D (1,309 vs 1,306), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon Vega 6 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 2013. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon Vega 6 makes the most sense today based on the pricing and value data we have for this matchup.
