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

Radeon HD 8670M

2013

Why buy it

✅82.1% more average FPS across 50 tracked games in our benchmark data.
✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2013 hardware with 1 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 3.4 G3D/$ (Unknown MSRP vs $150 MSRP).
❌100% higher power demand at 100W vs 50W.

Radeon HD 8690A

2013

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 3.4 vs 0 G3D/$ ($150 MSRP vs Unknown MSRP).
