Delivering graphics-intensive applications can inherently consume a significant amount of bandwidth, especially with high resolutions and multiple displays.

Using HDX™ Graphics Superresolution upscaling can lower bandwidth usage for mixed workloads.

With HDX Graphics Superresolution upscaling, the VDA applies extra compression to the video resolution during encoding. The client then automatically upscales the regions back to their original resolution and quality using the GPU. This process is seamless to the end user and doesn’t cause any noticeable quality loss or affect the endpoint’s performance.

All Citrix® workloads will benefit from the HDX Graphics Superresolution upscaling technology. As the technology is not dependent on the presence of a server-side GPU, HDX Graphics Superresolution upscaling can reduce bandwidth consumption without the need for costly server-side GPUs.

When a server-side GPU is available, HDX Graphics Superresolution upscaling can work in tandem with new video codecs like H.265 and AV1.

Use cases

High resolution workloads with high-definition video content and endpoints with 10th-generation Intel CPUs or later with integrated Graphics, for example, will benefit from a reduction in bandwidth utilization and an increase in user experience by leveraging the integrated GPU’s capabilities for upscaling with Citrix HDX Graphics Superresolution upscaling technology.
