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

Radeon HD 7700-serie

2012

Why buy it

✅78.3% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 11.9 vs 0 G3D/$ ($159 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).

Trade-offs

❌2012 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌455.6% higher power demand at 250W vs 45W.

RadeonT Vega 8

2021

Why buy it

✅Radeon HD 7700-serie is already obsolete for modern gaming, so RadeonT Vega 8 is the less risky modern option long term.
✅Draws 45W instead of 250W, a 205W reduction.
✅More future proof: GCN 5.1 (2018−2022) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than Radeon HD 7700-serie across 50 tracked games in our benchmark data.
❌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.
