Remote server management or troubleshooting remote systems are some tasks that require a remote desktop solution. This is where the popular remote desktop protocols come into play: VNC vs RDP.
Although these two tools are similar in features and applications, RDP is a step ahead in terms of security, performance, and smooth user experience.
On the other hand, VNC also comes out ahead in terms of simplicity and cross-platform.
Overall, RDP is a better option if you prioritize performance and security, as the following comparisons prove. If you want to multiply these factors to have a smooth and fast remote experience, Buy admin RDP can end your limitations.
What is VNC?
VNC (Virtual Network Computing) is an RFB-based protocol that allows platform-independent viewing and control of the target device’s desktop.
Data transfer with VNC is done in pixel format. This means the screen image is sent as pixel frames and reconstructed on the client side.
This method allows instant viewing of the remote device’s screen, but because it transfers a large amount of image data, it usually consumes more bandwidth and slows down.
What is RDP?
RDP (Remote Desktop Protocol) is a proprietary Microsoft protocol allowing users to connect to a remote device over TCP/IP and port 3389.
RDP encapsulates data in a series of encrypted packets, which prevents unauthorized access and eavesdropping.
Since RDP is a proprietary Microsoft protocol, the RDP server only works with Windows. However, the RDP client is available for almost all operating systems, including Mac, Linux, and Android.
VNC vs RDP: Quick Comparison
| Feature | RDP | VNC |
| Mechanism | Resource sharing: sends graphics commands | Screen sharing: sends image data |
| Speed and Performance | Fast: optimized for performance | Slow: higher bandwidth usage |
| Supported Platforms | Best on Windows: limited on others | Fully cross-platform |
| Security | Secure with encryption and NLA | Less secure without additional measures |
| Use Cases | Server management, remote work, software testing | Technical support, training, collaboration |
| Ease of use | More complex setup | Simple and beginner-friendly setup |
| Cost | Free with basic features: paid for advanced | Free with basic features: paid for advanced |
What Are the Differences between RDP and VNC?
VNC and RDP each excel in certain areas. To make the right choice, you must identify your needs and find the protocol that best meets those needs.
VNC vs RDP: Mechanism
VNC is a pixel-based protocol. In this way, the VNC server shares screen data as image frames with the client. The client uses this data to reconstruct the remote screen image and display the changes in real time.
The client also sends mouse and keyboard inputs to the server, reconstructing them on the remote device.
In RDP, the client connects to the RDP Server on the remote device using port 3389. The mouse and keyboard changes are then sent from the user device to the remote device over a dedicated TCP/IP channel.
In RDP, instead of image exchange, graphics commands and data required to reconstruct the user interface are sent to the client.
The screen reconstruction is also performed using this received data to provide a smooth and optimized user experience.
RDP vs VNC: Speed and Performance
VNC sends the entire screen content in pixels, which increases bandwidth consumption and causes high latency in interactive operations.
However, RDP provides the conditions for a smooth user experience with techniques such as data compression and Efficient Multimedia Redirection (EMR), RDP integration with the remote system’s graphics hardware, and the ability to customize display settings.
So, RDP has better performance and speed than VNC.
VNC vs RDP: Supported Platforms
RDP is a proprietary protocol from Microsoft that is optimized for Windows systems by default. Although the RDP client can be used on various platforms, such as Linux and Mac, it may have limited functionality on non-Windows systems.
On the other hand, VNC is available on all platforms, and there are no restrictions on using VNC applications on various platforms with different operating systems.
So, regarding platform compatibility, VNC gives you more freedom.
RDP vs VNC: Security
RDP establishes connections using port forwarding, while VNC uses cloud connections.
Although the port forwarding technique is exposed, RDP compensates for this deficiency by implementing security techniques such as internal encryption and Network-Level Authentication (NLA).
If the VNC software is equipped with a security mechanism, it can provide security similar to RDP’s. But if not, the chances of your device being infected with malware or other security threats increase significantly.
So, in terms of security, RDP wins the race.
VNC vs RDP: Use Cases
VNC is a screen-sharing platform that allows users to control a device remotely. Simultaneous access to a device with VNC means that the screen is shared equally with all users, and they all face the same scene.
This type of access is beneficial in the following areas:
- Resolving technical issues by the support team
- Regular maintenance
- Cross-Platform Screen Sharing
- Remote Training
- Headless Systems Control
- Collaborative Team Meetings
- Software Development and Testing
- Remote device management for people with physical disabilities
- Access to virtual labs
RDP is a resource-sharing platform where users independently connect to the remote device and perform their desired tasks.
This type of access is helpful in the following areas:
- Server management
- Employee access to their workstations
- Update and troubleshoot system problems
- Remote work
- Technical support
- Management of multiple workstations
- Access to sensitive and specialized software
- Testing software in different environments
- Data center management
- Creating virtual desktops for users
Each protocol has specific applications, and the choice between them depends on your needs and usage scenario.
So, in terms of Use Cases, there is no winner.
VNC vs RDP: Ease of use
RDP has a slightly steeper learning curve for configuring settings and features, which can be difficult for beginners.
VNC has an easier configuration process and can do its job well with minimal settings, making it easy for beginners to work with.
So, when it comes to accessibility and ease of use, VNC is more suitable than RDP.
RDP vs VNC: Cost
Both RDP and VNC are free. If you can install a free client like Windows Remote Desktop Connection for RDP and VNC viewers for VNC, you can use them for free for remote connections. However, if you need more advanced features like file sharing or multi-monitor, you can use premium software like AnyDesk and TeamViewer.
Which one should You use? RDP or VNC?
Choosing between RDP and VNC depends entirely on your specific needs and environment. But if you want to consider the right option for different situations, consider the following scenarios:
