The NVIDIA Quadro K420 delivers power-efficient 3D application performance and capability. 1 GB of DDR3 GPU memory with fast bandwidth enables you to create complex 3D models, and a flexible single-slot and low-profile form factor makes it compatible with even the most space and power-constrained chassis. Plus, a display engine drives up to four displays with DisplayPort 1.2 support for ultra-high resolutions like 3840 x 2160 at 60 Hz with 30-bit color. Quadro cards are certified with a broad range of sophisticated professional applications, tested by leading workstation manufacturers, and backed by a global team of support specialists, giving you the peace of mind to focus on doing your best work. Whether you're developing revolutionary products or telling spectacularly vivid visual stories, Quadro gives you the performance to do it brilliantly.
