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

Quadro K4000

2013

Why buy it

✅4.6% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with 3 GB vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌2013 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
1506.3% HIGHER MSRP
$1,269 MSRPvs$79 MSRP
❌Lower G3D Mark per dollar, at 2.1 vs 33.8 G3D/$ ($1,269 MSRP vs $79 MSRP).

Radeon RX 550

2017

Why buy it

✅Costs $1,190 less on MSRP ($79 MSRP vs $1,269 MSRP).
✅Delivers 1479.7% more G3D Mark for each dollar spent, at 33.8 vs 2.1 G3D/$ ($79 MSRP vs $1,269 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅33.3% more VRAM for high-resolution textures and newer games (4 GB vs 3 GB).
✅Quadro K4000 is already obsolete for modern gaming, so Radeon RX 550 is the less risky modern option long term.

Trade-offs

❌Lower average FPS than Quadro K4000 across 50 tracked games in our benchmark data.
❌2017 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

Quadro K4000 is the faster gaming card right now. In our data, it leads by 4.6% in average FPS across 50 tracked games in our benchmark data and by 1.7% in PassMark G3D (2,719 vs 2,674), so the answer here is pretty clean.

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

Radeon RX 550 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 3 GB of VRAM, the newer feature stack, with FSR Upscaling / FSR 4 (2025) and FSR Frame Generation (2023), while Quadro K4000 is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 14nm process instead of 28nm, and a newer 2017 generation instead of 2013. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 550 makes the most sense to buy today. It is $1,190 cheaper on MSRP at $79 vs $1,269, and it leads G3D-per-dollar by 1479.7% (33.8 vs 2.1), which is enough to swing the recommendation its way. Quadro K4000 still makes more sense if max raw gaming performance matters more than value.
