See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
Iris Plus Graphics 645
2019Why buy it
- ✅Draws 15W instead of 142W, a 127W reduction.
- ✅More future proof: Generation 9.5 (2016−2020) on 14nm with a newer platform for upcoming games.
Trade-offs
- ❌Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
- ❌2019 hardware with Unknown 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 $1,199 MSRP).
Quadro 4000
2010Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 1.2 vs 0 G3D/$ ($1,199 MSRP vs Unknown MSRP).
- ✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
- ✅Iris Plus Graphics 645 is already obsolete for modern gaming, so Quadro 4000 is the less risky modern option long term.
Trade-offs
- ❌2010 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌846.7% higher power demand at 142W vs 15W.
