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

Radeon 550X

2019

Why buy it

✅37.2% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 13.5 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
✅Radeon HD 7770M is already obsolete for modern gaming, so Radeon 550X is the less risky modern option long term.

Trade-offs

❌2019 hardware with 512 MB of VRAM already sits in legacy territory for modern games.
❌56.3% higher power demand at 50W vs 32W.

Radeon HD 7770M

2012

Why buy it

✅Draws 32W instead of 50W, a 18W reduction.

Trade-offs

❌Lower average FPS than Radeon 550X across 50 tracked games in our benchmark data.
❌2012 hardware with 512 MB 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 13.5 G3D/$ (Unknown MSRP vs $109 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
