GeForce 6600
2012Why buy it
- ✅Draws 140W instead of 250W, a 110W reduction.
Trade-offs
- ❌Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
- ❌2012 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌170% HIGHER MSRP$270 MSRPvs$100 MSRP
- ❌Lower G3D Mark per dollar, at 0.3 vs 0.8 G3D/$ ($270 MSRP vs $100 MSRP).
Radeon X1650 Pro
2023Why buy it
- ✅Costs $170 less on MSRP ($100 MSRP vs $270 MSRP).
- ✅Delivers 166.9% more G3D Mark for each dollar spent, at 0.8 vs 0.3 G3D/$ ($100 MSRP vs $270 MSRP).
- ✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
- ✅Better long-term bet: RDNA 2.0 (2020−2025) on 7nm gives it a newer hardware base for upcoming games.
Trade-offs
- ❌78.6% higher power demand at 250W vs 140W.
