Radeon HD 6990M
2011Why buy it
- ✅Competitive enough if your priority is price, power, or specific feature preference.
Trade-offs
- ❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
- ❌Very weak future-proofing: 2011-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
- ❌Lower G3D Mark per dollar, at 0 vs 8.0 G3D/$ (Unknown MSRP vs $400 MSRP).
Radeon R9 M290X
2014Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 8.0 vs 0 G3D/$ ($400 MSRP vs Unknown MSRP).
- ✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
- ✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.
Trade-offs
- ❌Very weak future-proofing: 2014-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
