While RDP and VNC share these core similarities, their differences in functionality, performance, and use cases are what truly set them apart.
Differences between RDP and VNC
The two methods may sound very similar, but a deeper look reveals that the differences between them are striking. The main difference is that RDP is a virtual session while VNC captures the physical display, meaning you see exactly what the remote user sees. Here are a few other differences between the two technologies:
Platform compatibility: VNC is designed to support multiple platforms, allowing for shared screens and keyboards between devices using Windows, Mac, Linux, Android, iOS, and Raspberry Pi operating systems. RDP, on the other hand, is proprietary and only works for one specific operating system. This makes RDP quite limited and not the most compatible remote desktop solution.
If you’re aiming for a broad implementation of a remote desktop tool, the software you choose will likely need to function across an array of devices and operating systems, including mobile phones, PCs, Linux and iOS devices, Raspberry Pi boards, and Mac computers.
Connection modes: RDP works as though the user has directly logged into the physical server and supports many remote users all logged into the same server. VNC connects the remote user to the computer itself by sharing its screen, mouse, and keyboard.
This means that several users can connect to the same server at the same time. All the users will be able to see the same screen and type on the same keyboard. The robust device access through desktop sharing systems from VNC allows users to take full control of a remote computer.
This difference in remote desktop performance greatly aids productivity for individuals, organizations, and IT specialists.
When deciding how remote access software will meet your business requirements, this difference in VNC and RDP performance is a useful aspect to consider as it makes VNC better suited to support use cases involving troubleshooting.
