The AMD Radeon HD 8790m is a dedicated notebook GPU, and its driver allows Windows and your applications to communicate with the graphics hardware. Installing a compatible AMD graphics driver helps enable proper display resolutions, hardware-accelerated rendering, and access to available graphics settings. Before downloading, check the package’s compatibility with your laptop and Windows version rather than assuming every release supports this older GPU.

Key Features

• Display configuration: Enables supported screen resolutions, color settings, and external-monitor options, depending on your notebook’s display connections.
• Graphics acceleration: Provides the software support needed for compatible games, 3D applications, and other GPU-accelerated tasks.
• Video playback support: Allows supported media software to use the GPU’s video-decoding capabilities, which can reduce CPU workload during playback.
• Notebook graphics integration: Works with compatible laptop graphics configurations, including switchable graphics where supported. Some systems require manufacturer-customized drivers for proper operation.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and expand Display adapters to check for the AMD Radeon HD 8790m. Verify whether you are running Windows 11, 10, 8, or 7, and check your system architecture before selecting a download.

1. Choose a compatible driver package. Read the supported-device and operating-system information carefully. Official driver availability varies for this legacy GPU; Windows 11 compatibility should not be assumed. For laptops with switchable graphics, check whether the notebook manufacturer recommends a specific AMD and integrated-graphics driver combination.

1. Prepare the laptop. Save open work, connect the power adapter, and consider creating a Windows restore point. If you are replacing a problematic driver, download the replacement before removing the existing installation.

1. Run the installer. Extract the download if necessary, launch the setup program, and approve the Windows permission prompt. Follow the installation instructions. If the installer reports unsupported hardware or an incompatible operating system, stop and verify the package rather than forcing installation.

1. Restart and check operation. Reboot when prompted, then confirm that Device Manager lists the GPU without a warning icon. Test the display resolution, external monitor if used, and a familiar application. If new problems appear, use Device Manager’s rollback option when available or reinstall the laptop manufacturer’s recommended driver.

Common Issues and Fixes

• Install fails or rolls back: The HD 8790M often needs OEM/laptop-specific or legacy AMD packages. Remove old drivers with DDU in Safe Mode, reboot, then run the matching installer as administrator.
• Device not detected: Confirm switchable graphics is enabled in BIOS/UEFI and the GPU appears in Device Manager. Install the Intel integrated GPU/chipset driver first, then the AMD HD 8790M driver.
• Version conflicts: Windows Update may overwrite the AMD driver with a generic one. Roll back the driver, pause automatic driver updates, and reinstall the correct AMD package after cleaning old versions.
