Verdict

The NVIDIA Quadro K4000 is a single-slot workstation graphics card launched in 2013, built on the 28nm Kepler architecture (GK106) with 768 CUDA cores and 3GB of GDDR5 memory on a 192-bit interface providing 134 GB/s bandwidth. Operating at a base clock of 810 MHz with an 80W TDP, it was specifically designed for professional 3D modeling and CAD applications, offering certified stability and support for up to four simultaneous displays via DisplayPort 1.2 and DVI-I DL. Its primary advantages include high power efficiency, a slim form factor that fits into compact workstations, and reliable ISV-certified drivers for industries like manufacturing and media. However, its main drawbacks are its aging performance compared to modern standards, lack of native DirectX 12 feature level support, and poor value for gaming due to its specialized, non-consumer driver focus.
