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 W9100 vs Radeon RX 6400: 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 W9100

2014

Why buy it

  • ✅300% more VRAM for high-resolution textures and newer games (16 GB vs 4 GB).

Trade-offs

  • ❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
  • ❌2014 hardware with 16 GB of VRAM already sits in legacy territory for modern games.
  • ❌
    2415.7% HIGHER MSRP
    $4,000 MSRPvs$159 MSRP
  • ❌Lower G3D Mark per dollar, at 1.9 vs 48.6 G3D/$ ($4,000 MSRP vs $159 MSRP).
  • ❌418.9% higher power demand at 275W vs 53W.

Radeon RX 6400

2022

Why buy it

  • ✅Costs $3,841 less on MSRP ($159 MSRP vs $4,000 MSRP).
  • ✅Delivers 2409.2% more G3D Mark for each dollar spent, at 48.6 vs 1.9 G3D/$ ($159 MSRP vs $4,000 MSRP).
  • ✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
  • ✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
  • ✅Draws 53W instead of 275W, a 222W reduction.

Trade-offs

  • ❌Less VRAM, with 4 GB vs 16 GB for high-resolution textures and newer games.

Quick Answers

Which GPU is faster for gaming right now?
FirePro W9100 is the faster gaming card right now based on the synthetic data we have. It leads by 0.3% in PassMark G3D (7,748 vs 7,728), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX 6400 is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while FirePro W9100 is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 6nm process instead of 28nm, 12 vs 0 ray-tracing units, and a newer 2022 generation instead of 2014. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon RX 6400 makes the most sense to buy today. It is $3,841 cheaper on MSRP at $159 vs $4,000, and it leads G3D-per-dollar by 2409.2% (48.6 vs 1.9), which is enough to swing the recommendation its way. FirePro W9100 still makes more sense if max raw gaming performance matters more than value.
