HP's Quadro K620 Graphics Card features Kepler architecture and touts UHD-capable outputs on a half-height, half-length board. The GPU features 384 CUDA cores coupled to 2GB of DDR3 vRAM with a 128-bit memory bus. Using supported APIs and CUDA, that computing performance can translate into high resolution and realistic real-time 2D and 3D graphics rendering or improved computing speed with hardware acceleration.
The output panel on this card features a single DisplayPort connection and a single DVI connection. Up to four monitors can be simultaneously supported by a single card, using a separately available MST hub, to create high-resolution video walls with your workstation or for more desktop real-estate to increase productivity. Separately available adapters can be used with this card to drive other kinds of displays and projectors.
For cooling, PNY implemented an active fansink cooler. This cooler uses a radial fan to force air through the card's heatsink, dissipating heat from the GPU and other internal components. This cooling configuration is best suited for cases with unrestricted airflow.

NVIDIA CUDA Architecture
Parallel-computing architecture that tightly integrates advanced visualization and compute features to significantly accelerate professional workflows.
NVIDIA Scalable Geometry Engine
Dramatically improves geometry performance across a broad range of CAD, DCC and medical applications, enabling you to work interactively with complex models and scenes.
NVIDIA Parallel DataCache
Supports a true cache hierarchy combined with on-chip shared memory. L1 and L2 caches drive exception throughput, accelerating features such as real-time ray tracing, physics, and texture filtering.
increases the number of unique textures available to shaders at run-time, enabling vastly more different materials and richer texture detail in scenes.
NVIDIA Streaming Multiprocessor
Delivers more processing performance and efficiency through this streaming multiprocessor design that allows a greater percentage of space to be applied to processing cores versus control logic.
Dedicated H.264 encode engine that is independent of 3D/compute pipeline and delivers faster than real-time performance for transcoding, video editing, and other encoding applications.
Unified Driver Architecture
Provides forward and backward compatibility with software drivers, simplifying upgrading to a new Quadro solution whenever you're ready.
NVIDIA GPU Boost
Increases application performance through automatic adjustment of the GPU clock to take maximum advantage of the power and thermal headroom of the card in real-time.
NVIDIA Multi-GPU Technology
NVIDIA Multi-GPU powered workstations combine the visualization and interactive design capability of multiple GPUs, by leveraging any combination of Quadro and Tesla GPUs to intelligently scale the performance of your application and dramatically speed up your production workflow.
Image Quality Features
Full-Scene Anti-Aliasing (FSAA)
Up to 64X FSAA for dramatically reducing visual aliasing artifacts or "jaggies," resulting in improved image quality and realistic scenes.
NVIDIA FXAA and TXAA
Reduces visible aliasing and delivers higher image quality without the performance hit by harnessing the power of the GPU's CUDA cores and new film-style AA techniques.
Quadro Tessellation Engines automatically generate finely detailed geometry for cinematic quality environments and scenes, without sacrificing performance.
16K Texture and Render Processing
Provides the ability to texture from and render to 16K x 16K surfaces. Beneficial for applications that demand high resolution and quality image processing.
NVIDIA Quadro Mosaic Technology
Enables transparent scaling of the desktop and applications across up to 16 displays from 4 GPUs from a single workstation while delivering full performance and image quality.
All-new display engine drives up to four displays simultaneously and fully supports the Display Port 1.2 standard capable of resolutions such as 3840 x 2160 at 60Hz, making it easy to deploy multiple displays across a desktop, build an expansive digital signage wall, or create a sophisticated stereoscopic 3D CAVE environment.
NVIDIA 3D Vision Support
When used with a 3D Vision compatible monitor and 3D Vision active-shutter glasses, full-HD resolution images are delivered to each eye. Additionally, with a 3D LightBoost compatible screen, image brightness will be maintained while using the glasses and ghosting will be reduced.
Deep Color Processing and Display
Preserve color detail and precision throughout the processing and display pipeline for smooth gradients transitions, even on high dynamic range imagery. Each color component can be processed at up to 32-bit floating point precision and displayed at up to 12-bit precision with supported DisplayPort 1.2 or HDMI 1.4 displays
