AMD Radeon HD 7640G + HD 8600/8700M Dual Graphics - Technical Information.


The AMD Radeon HD 7640G is an integrated graphics unit, while the HD 8600/8700M is a dedicated discrete graphics card. When these two graphics units work in dual graphics mode, it is a hybrid solution that combines the power of both graphics units to improve graphics performance. Here is some technical information about this dual graphics setup:

1. Architecture and GPU:
The AMD Radeon HD 7640G is based on the VLIW4 architecture and is part of AMD's Trinity APU series. The HD 8600/8700M is based on the GCN (Graphics Core Next) architecture and belongs to the Radeon HD 8000M series. The GCN architecture is more modern and offers better performance and efficiency compared to the VLIW4 architecture.

2. Performance:
Dual Graphics mode combines the power of integrated and discrete graphics units to improve graphics performance. This can help boost performance in games and other graphics-intensive applications, especially at lower resolutions and settings.

3. Memory:
Since the HD 7640G is an integrated graphics unit, it shares system memory with the CPU, while the HD 8600/8700M has its own dedicated VRAM.

4. Drivers:
It is important to download and install the latest drivers from the official AMD website to ensure the best performance and compatibility. The correct drivers should be installed for both the integrated and dedicated graphics units.

5. Power Consumption and Energy Efficiency:
Dual graphics mode can improve the overall performance of the system, but it can also increase power consumption. Efficient power management and cooling are important to avoid overheating and other problems.

6. Supported Technologies:
The Radeon HD 8600/8700M supports modern graphics technologies such as DirectX 11.2, OpenGL 4.3 and OpenCL 1.2. Dual Graphics mode can leverage these technologies to improve performance in supported applications.

Overall, the dual graphics setup with the AMD Radeon HD 7640G and HD 8600/8700M offers improved graphics performance for users looking for a cost-effective way to enhance their gaming and multimedia experience.

AMD Radeon HD 7640G + HD 8600/8700M Dual Graphics, known issues and bugs.


Dual graphics systems such as the AMD Radeon HD 7640G + HD 8600/8700M can experience some issues, particularly related to the integration of two different graphics units. Here are some known issues and possible bugs that users may encounter:

1. Driver incompatibility and stability:
Using two different graphics units requires careful tuning of drivers to ensure smooth performance. In some cases, driver incompatibilities may occur, resulting in graphics errors, application crashes, or other stability issues.

2. Performance Imbalance:
Since the HD 7640G is an integrated graphics unit and the HD 8600/8700M is a dedicated discrete graphics card, performance imbalance may occur, especially if the graphics units are not synchronized effectively. This can lead to inefficient use of resources and affect the overall performance of the system.

3. Compatibility Issues with Specific Games or Applications:
Some games or applications may not work properly with the dual graphics setup, especially if they have specific graphics requirements or are not well compatible with the two graphics units.

4. Overheating and thermal issues:
Using integrated and dedicated graphics at the same time can lead to increased heat generation, especially if the system is not sufficiently cooled. This can cause thermal throttling which can affect performance.

5. Screen flickering or graphics artifacts:
Users may notice screen flickering or graphics artifacts that could indicate hardware issues with one of the graphics units or driver issues. This can be resolved by updating drivers, adjusting graphics settings, or checking the physical connection of the display.

It is important to note that not all users experience these problems, and many of them can be resolved by updating drivers, adjusting graphics settings, or using third-party applications. If users experience specific issues with their AMD Radeon HD 7640G + HD 8600/8700M Dual Graphics setup, it is advisable to search for solutions on forums, AMD support pages, or directly from AMD support representatives.
