Radeon RX 640 vs Radeon RX Vega 11: 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 RX 640

2019

Why buy it

  • 10.3% more average FPS across 50 tracked games in our benchmark data.
  • Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
  • 100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
  • Radeon RX Vega 11 is already obsolete for modern gaming, so Radeon RX 640 is the less risky modern option long term.

Trade-offs

  • Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • 6.7% HIGHER MSRP
    $159 MSRPvs$149 MSRP
  • 42.9% higher power demand at 50W vs 35W.

Radeon RX Vega 11

2018

Why buy it

  • Costs $10 less on MSRP ($149 MSRP vs $159 MSRP).
  • Draws 35W instead of 50W, a 15W reduction.

Trade-offs

  • Lower average FPS than Radeon RX 640 across 50 tracked games in our benchmark data.
  • Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
  • No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
  • 2018 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 640 is the faster gaming card right now. In our data, it leads by 10.3% in average FPS across 50 tracked games in our benchmark data and by 3.7% in PassMark G3D (2,172 vs 2,094), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX 640 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs Unknown of VRAM, native frame generation with FSR Frame Generation + AFMF (2023), while Radeon RX Vega 11 has no comparable frame-generation support, and a newer 2019 generation instead of 2018. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Radeon RX Vega 11 makes the most sense to buy today. It is $10 cheaper on MSRP at $149 vs $159, and it leads G3D-per-dollar by 2.9% (14.1 vs 13.7), which is enough to swing the recommendation its way. If you are mainly targeting 1080p, Radeon RX Vega 11 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon RX 640 has the stronger long-term case.
