Radeon Pro 450 vs Radeon RX 550: 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 Pro 450

2016

Why buy it

✅14.3% more average FPS across 50 tracked games in our benchmark data.
✅Draws 35W instead of 50W, a 15W reduction.
✅Measures 1mm instead of 155mm, a 154mm shorter card that is more SFF-friendly.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌2016 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 33.8 G3D/$ (Unknown MSRP vs $79 MSRP).

Radeon RX 550

2017

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 33.8 vs 0 G3D/$ ($79 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
✅Radeon Pro 450 is already obsolete for modern gaming, so Radeon RX 550 is the less risky modern option long term.

Trade-offs

❌Lower average FPS than Radeon Pro 450 across 50 tracked games in our benchmark data.
❌2017 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌42.9% higher power demand at 50W vs 35W.
❌15400% longer card at 155mm vs 1mm.

Quick Answers

Which GPU is faster for gaming right now?

Radeon Pro 450 is the faster gaming card right now. In our data, it leads by 14.3% in average FPS across 50 tracked games in our benchmark data and by 1.8% in PassMark G3D (2,723 vs 2,674), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon RX 550 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 (2023), while Radeon Pro 450 has no comparable frame-generation support, and a newer 2017 generation instead of 2016. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 550 makes the most sense today based on the pricing and value data we have for this matchup. Radeon Pro 450 still makes more sense if max raw gaming performance matters more than value.
