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

Radeon HD 7770M

2012

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
✅Radeon RX Vega 6 is already obsolete for modern gaming, so Radeon HD 7770M is the less risky modern option long term.
✅Draws 32W instead of 295W, a 263W reduction.

Trade-offs

❌Lower average FPS than Radeon RX Vega 6 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.

Radeon RX Vega 6

2017

Why buy it

✅164.0% more average FPS across 50 tracked games in our benchmark data.
✅More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
❌2017 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌821.9% higher power demand at 295W vs 32W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX Vega 6 is the faster gaming card right now. In our data, it leads by 164.0% in average FPS across 50 tracked games in our benchmark data.
