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

Radeon HD 4770

2009

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 8.3 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).

Trade-offs

❌Lower average FPS than Radeon Vega 3 across 50 tracked games in our benchmark data.
❌2009 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌77.8% higher power demand at 80W vs 45W.

Radeon Vega 3

2021

Why buy it

✅41.1% more average FPS across 50 tracked games in our benchmark data.
✅Radeon HD 4770 is already obsolete for modern gaming, so Radeon Vega 3 is the less risky modern option long term.
✅Draws 45W instead of 80W, a 35W reduction.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
❌2021 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
