See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
FireStream 9250
2008Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 1.2 vs 0 G3D/$ ($999 MSRP vs Unknown MSRP).
Trade-offs
- ❌Less VRAM, with 1 GB vs 4 GB for high-resolution textures and newer games.
- ❌2008 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌400% higher power demand at 150W vs 30W.
Quadro K620M
2015Why buy it
- ✅300% more VRAM for high-resolution textures and newer games (4 GB vs 1 GB).
- ✅Draws 30W instead of 150W, a 120W reduction.
- ✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.
Trade-offs
- ❌2015 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌Lower G3D Mark per dollar, at 0 vs 1.2 G3D/$ (Unknown MSRP vs $999 MSRP).
