PNY Quadro K420 2GB GDDR5 workstation
The Pascal-based Quadro P400 doubles visualization performance over the Maxwell K420 while fitting into a low-profile, 41W single-slot design with 2GB of GDDR5 memory. Its three DisplayPort 1.4 outputs and dedicated H.264/HEVC encode engines provide flexible multi-monitor setups and smooth HDR video playback in a compact workstation. This card is best for entry-level CAD users and financial traders needing certified driver stability and triple-display support, not for GPU compute or AI workloads.
