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
2019Why 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
2018Why 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.
