Using a Kepler architecture chip, the HP Quadro K420 Graphics Card is optimized for workstation and professional graphics use. The GPU features 192 CUDA cores coupled to 1GB of DDR3 vRAM with a 128-bit memory bus providing 366.4 GFLOPS of single-precision computing power. Using supported APIs and CUDA, that computing power can translate into accelerated graphics rendering or computing speed with compatible applications.
The output panel on this card features a DisplayPort terminal and a Dual-Link DVI-I terminal. Using an MST hub, up to four displays can be supported by a single card to create high-resolution video walls with your workstation or for more desktop real-estate to increase productivity. Multiple Quadro cards can be used together to expand the card's multi-display and resolution capabilities. Included with the card is a DisplayPort to DVI adapter and a low-profile bracket for use in smaller workstations.
For cooling HP implemented an active fansink cooler. This solution is quiet and efficient. Forcing air over heat-generating sections of the graphics card. This cooling configuration saves space and will fit inside workstation case configurations where space between components is at a premium.

GPU Features
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.
Bindless Textures
Dramatically increases the number of unique textures available to shaders at run-time, enabling more discrete materials and richer texture detail in scenes.
H.264 Encoder
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 (requires application support).
Dynamic Parallelism
Simplifies GPU programming by allowing programmers to easily accelerate all parallel nested loops - resulting in a GPU dynamically spawning new threads on its own without going back to the CPU.
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.
GPU Tesselation
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.
Display Features
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.
Multi-Display Support
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 60 Hz, 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, high-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.
3D Stereo Synchronization
Use the included 3-pin mini-DIN connector to directly synchronize 3D stereo hardware to the GPU for robust control.
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
