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

Radeon Pro V620 MxGPU

2018

Why buy it

  • 166.7% more VRAM for high-resolution textures and newer games (32 GB vs 12 GB).

Trade-offs

  • Lower average FPS than Radeon RX 7800M across 50 tracked games in our benchmark data.
  • No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
  • Older hardware, 32 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • 66.7% higher power demand at 300W vs 180W.

Radeon RX 7800M

2024

Why buy it

  • 22.4% more average FPS across 50 tracked games in our benchmark data.
  • Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
  • Better long-term bet: RDNA 3.0 on 5nm gives it a newer hardware base for upcoming games.
  • Draws 180W instead of 300W, a 120W reduction.

Trade-offs

  • Less VRAM, with 12 GB vs 32 GB for high-resolution textures and newer games.

Quick Answers

Which GPU is faster for gaming right now?
Radeon RX 7800M is the faster gaming card right now. In our data, it leads by 22.4% in average FPS across 50 tracked games in our benchmark data and by 2.2% in PassMark G3D (15,984 vs 15,633), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX 7800M is the safer long-term pick for 2026 and beyond. The case is simple: native frame generation with FSR Frame Generation + AFMF (2023), while Radeon Pro V620 MxGPU has no comparable frame-generation support, a 5nm process instead of 14nm, 60 vs 0 ray-tracing units, and a newer 2024 generation instead of 2018. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon RX 7800M makes the most sense today based on the pricing and value data we have for this matchup.
