AVD D8ads v5 (no GPU): RDP-TCP versus RDP Shortpath
Test Engineer: Benny Tritsch
Date of test: 30 August 2022
Testable question: What is the difference between RDP-TCP and RDP Shortpath on an AVD D8ads v5 VM (no GPU)?
System Under Test Azure West Europe, Azure Virtual Desktop VM type D8ads v5, AMD EPYC 7763 8vCPUs @ 2.4GHz, 32GB RAM, HDD 126GB, no GPU.
System Under Test Azure West Europe, Azure Virtual Desktop VM type D8ads v5, AMD EPYC 7763 8vCPUs @ 2.4GHz, 32GB RAM, HDD 126GB, no GPU.
Connection RDP-TCP, 23ms round trip time.
Connection RDP Shortpath, 15ms round trip time.
| Simload and Link | View and Telemetry Type | Observation |
|---|---|---|
| SL1-ChromeGifScroll | SxS View - Standard | User experience is similar, but RDP Shortpath (UDP) reduces CPU load and incoming network bandwidth (no handshake). |
| SL1-RollercoasterDX9 | SxS View - Standard | Network optimization after 10 seconds application runtime. RDP Shortpath (UDP) reduces incoming network bandwidth. |
Result: While the user experience is similar on both sides, RDP Shortpath requires less network bandwidth.
AVD NV6 with NVIDIA M60 GPU: RDP-TCP versus RDP Shortpath
Test Engineer: Benny Tritsch
Date of test: 30 August 2022
Testable question: What is the difference between RDP-TCP and RDP Shortpath on an AVD NV6 VM (with GPU)?
System Under Test Azure West Europe, Azure Virtual Desktop VM type NV6, Intel Xeon E5-2690 v3 6vCPUs @ 2.6GHz, 56GB RAM, Virtual HD ATA Device 340GB, NVIDIA M60 GPU (1/2 Card), 8GB VRAM.

| Simload and Link | View and Telemetry Type | Observation |
|---|---|---|
| SL1-MSEdgeCarVisualizer | SxS View - GPU | RDP-TCP network optimization every 10 seconds. RDP Shortpath (UDP) reduces CPU load and outgoing network bandwidth. |
| SL1-MSEdgeVideoConf6 | SxS View - GPU | RDP Shortpath (UDP) reduces CPU load and network bandwidth, but increases GPU video decode/processing (video offloading). |
| SL1-WMPlayer720pMP4 | SxS View - GPU | RDP Shortpath (UDP) reduces CPU load and network bandwidth significantly, but increases GPU video processing. |
| SL1-DominoOpenGL | SxS View - GPU | RDP Shortpath (UDP) produces a slightly better user experience (frame rate). It also reduces CPU load and network bandwidth. |
| SL1-FurMarkOpenGL | SxS View - GPU | RDP-TCP network optimization after 10 seconds application runtime. RDP Shortpath (UDP) produces a slightly better user experience (frame rate). It also reduces CPU load and network bandwidth. |
Result: RDP Shortpath reduces CPU load and network bandwidth used by the GPU-accelerated Azure VM.
