Best practices for sizing and configuring solutions requiring graphics accelerators include:

• NVIDIA vPC licenses support up to 2 GB of video buffer and up to 2 x 4K monitors to cover most traditional VDI users. Maximum node density for graphics-accelerated use can typically be calculated as the available video buffer per node divided by the video buffer size.
• The addition of GPU cards does not necessarily reduce CPU utilization. Instead, it enhances the user experience and offloads specific operations that are best performed by the GPU.
• Dell Technologies recommends using Thinwire, the Citrix default display protocol, for most use cases. For 3D or higher interactive graphics, HDX 3D Pro can be used to encode the entire screen using hardware acceleration when combined with NVIDIA vGPU. NVIDIA GPUs are equipped with encoders that support HDX 3D Pro.
• Virtual workstations are typically configured with at least 2 GB video buffer.
• For solutions that use NVIDIA M10 GPU cards in a solution, Dell Technologies recommends a maximum memory capacity of less than 1 TB, due to limitations in the Maxwell architecture. Newer NVIDIA GPU architectures do not have the same limitation.
