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

FirePro D300

2014

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌2014 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
270.4% HIGHER MSRP
$500 MSRPvs$135 MSRP
❌Lower G3D Mark per dollar, at 11.4 vs 44.3 G3D/$ ($500 MSRP vs $135 MSRP).
❌200% higher power demand at 150W vs 50W.

RTX A400

2024

Why buy it

✅Costs $365 less on MSRP ($135 MSRP vs $500 MSRP).
✅Delivers 287.3% more G3D Mark for each dollar spent, at 44.3 vs 11.4 G3D/$ ($135 MSRP vs $500 MSRP).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.
✅Draws 50W instead of 150W, a 100W reduction.

Trade-offs

❌Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Quick Answers

Which GPU is faster for gaming right now?

RTX A400 is the faster gaming card right now based on the synthetic data we have. It leads by 4.6% in PassMark G3D (5,983 vs 5,722), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

RTX A400 is the safer long-term pick for 2026 and beyond. The case is simple: a 8nm process instead of 28nm, 6 vs 0 ray-tracing units, and a newer 2024 generation instead of 2014. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

RTX A400 makes the most sense to buy today. It is $365 cheaper on MSRP at $135 vs $500, and it leads G3D-per-dollar by 287.3% (44.3 vs 11.4), so the value case lines up with the gaming result.
