GeForce GTX 645
2010Why buy it
- ✅Costs $50 less on MSRP ($150 MSRP vs $200 MSRP).
- ✅Delivers 31% more G3D Mark for each dollar spent, at 12.5 vs 9.6 G3D/$ ($150 MSRP vs $200 MSRP).
Trade-offs
- ❌Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
- ❌Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
- ❌700% higher power demand at 200W vs 25W.
Quadro M520
2017Why buy it
- ✅100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
- ✅Draws 25W instead of 200W, a 175W reduction.
- ✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.
Trade-offs
- ❌Very weak future-proofing: 2017-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
- ❌33.3% HIGHER MSRP$200 MSRPvs$150 MSRP
- ❌Lower G3D Mark per dollar, at 9.6 vs 12.5 G3D/$ ($200 MSRP vs $150 MSRP).
