Trade-offs

  • Lower average FPS than RTX A4000H across 50 tracked games in our benchmark data.
  • Lower G3D Mark per dollar, at 0 vs 11.8 G3D/$ (Unknown MSRP vs $1,000 MSRP).

RTX A4000H

2021

Why buy it

  • 83.2% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 100+% more G3D Mark for each dollar spent, at 11.8 vs 0 G3D/$ ($1,000 MSRP vs Unknown MSRP).
  • More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

  • No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
  • 250% higher power demand at 140W vs 40W.

Quick Answers

Which GPU is faster for gaming right now?
RTX A4000H is the faster gaming card right now. In our data, it leads by 83.2% in average FPS across 50 tracked games in our benchmark data and by 0.9% in PassMark G3D (11,815 vs 11,715), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Quadro RTX 4000 (Mobile) is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with DLSS 3.5 Super Resolution (2023) and DLSS 3.5 + Frame Generation (2023), while RTX A4000H is limited to no meaningful modern upscaling stack and no comparable frame-generation support. That still leaves it as the safer long-term option on hardware alone.
Which GPU is the better buy today?
RTX A4000H makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, RTX A4000H is the easier value choice. If you care more about 1080p and some 1440p headroom, Quadro RTX 4000 (Mobile) has the stronger long-term case.
