Parallels using AMD Radeon RX 6900 XT OpenGL Engine (Compat) - Technical Information.


Using the AMD Radeon RX 6900 XT OpenGL Engine in Parallels, a virtualization software for macOS, allows users to run graphics-intensive applications and games within virtual machines (VMs). Here is the technical information and some key points about compatibility and performance:

AMD Radeon RX 6900 XT Technical Information:


1. GPU Architecture:

- The RX 6900 XT is based on AMD's RDNA 2 architecture , which offers significant improvements in performance and energy efficiency.

2. Compute Units (CUs) and Stream Processors:

- The GPU has 80 Compute Units (CUs) and 5120 Stream Processors, which are responsible for parallel calculations in graphics and computing applications.

3. Memory:

- It comes with 16GB GDDR6 VRAM, which is more than enough for high-resolution gaming and professional applications.

4. Memory Bandwidth:

- The card offers high memory bandwidth of up to 512GB/s, enabling fast data transfer between GPU and VRAM.

5. Interfaces:

- The RX 6900 XT supports PCIe 4.0, which ensures fast communication with the host system.

6. Supported APIs:

- DirectX 12 Ultimate, Vulkan 1.2, OpenGL 4.6 and OpenCL 2.1, ensuring wide compatibility with current applications and games.

Usage in Parallels:


1. Virtualization:

- Parallels Desktop makes it possible to run Windows, Linux and other operating systems on a Mac. The host's GPU performance can be partially passed on to the VM.

2. OpenGL Support:

- Parallels provides support for OpenGL, but performance depends heavily on the implementation and available resources of the host. Some demanding OpenGL applications and games may experience lower performance in a VM than on a native system.

3. Compatibility Mode:

- Compatibility mode (Compat) allows running a wider range of applications, but may result in a performance penalty compared to native execution.

Parallels using AMD Radeon RX 6900 XT OpenGL Engine (Compat), known issues and bugs.


1. Performance Issues:

- Graphically intensive applications or games may have lower performance in a VM than on a native system. This is due to the overhead costs of virtualization and the shared use of host resources.

2. **Driver incompatibilities**:
- Driver problems may occur, especially when using new or not fully supported graphics cards. Regular updates to Parallels software and AMD drivers are important.

3. Overheating:

- Intensive use of the GPU in a VM can cause the host system to overheat, especially if there is inadequate cooling. It is important to keep the system well cooled.

4. Compatibility with certain applications:

- Some professional applications or games may have problems running in a VM, whether due to OpenGL implementations or due to the virtualization environment itself.

5. Limited access to GPU resources :

- In a VM, access to GPU resources may be restricted, resulting in reduced performance. This particularly affects applications that require high graphics performance.

Optimization Tips:


- Update drivers:
Always keep the drivers for both Parallels and AMD GPU up to date.
- Allocate system resources:
Allocate sufficient RAM and CPU cores to the VM to ensure optimal performance.
- Ensure cooling:
Ensure good ventilation and cooling of the host system.
- Adjust Performance Modes:
Adjust performance modes in Parallels for better graphics performance.

By considering these aspects, many of the potential issues can be minimized and the performance of the AMD Radeon RX 6900 XT in a Parallels environment can be maximized.
