Radeon 550 vs Radeon RX 640: 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 550

2017

Why buy it

✅Costs $80 less on MSRP ($79 MSRP vs $159 MSRP).
✅Delivers 98.3% more G3D Mark for each dollar spent, at 27.1 vs 13.7 G3D/$ ($79 MSRP vs $159 MSRP).

Trade-offs

❌Lower average FPS than Radeon RX 640 across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌2017 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon RX 640

2019

Why buy it

✅40.2% 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 2 GB).
✅Radeon 550 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.
❌
101.3% HIGHER MSRP
$159 MSRPvs$79 MSRP
❌Lower G3D Mark per dollar, at 13.7 vs 27.1 G3D/$ ($159 MSRP vs $79 MSRP).

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 40.2% in average FPS across 50 tracked games in our benchmark data and by 1.5% in PassMark G3D (2,172 vs 2,140), 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 2 GB of VRAM, native frame generation with FSR Frame Generation + AFMF (2023), while Radeon 550 has no comparable frame-generation support, and a newer 2019 generation instead of 2017. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon 550 makes the most sense to buy today. It is $80 cheaper on MSRP at $79 vs $159, and it leads G3D-per-dollar by 98.3% (27.1 vs 13.7), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon 550 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon RX 640 has the stronger long-term case.
