About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

FirePro W4300 vs Quadro M620: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

FirePro W4300

2015

Why buy it

  • ✅Delivers 100+% more G3D Mark for each dollar spent, at 7.2 vs 0 G3D/$ ($379 MSRP vs Unknown MSRP).
  • ✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

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.
  • ❌66.7% higher power demand at 50W vs 30W.
  • ❌17000% longer card at 171mm vs 1mm.

Quadro M620

2017

Why buy it

  • ✅Draws 30W instead of 50W, a 20W reduction.
  • ✅Measures 1mm instead of 171mm, a 170mm shorter card that is more SFF-friendly.

Trade-offs

  • ❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
  • ❌2017 hardware with 2 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 7.2 G3D/$ (Unknown MSRP vs $379 MSRP).
