Developers can access Intel's processor graphics GPU capabilities through the Intel® Media SDK and Intel® SDK for OpenCL™ Applications. This article provides more information on how the software, driver, and hardware layers map together.
Delivery Models
There are two different packaging/delivery models:
- For Windows* Client: all components needed to run applications written with these SDKs are distributed with the Intel graphics driver. These components are intended to be updated on a separate cadence than Media SDK/OpenCL installs. Drivers are released separately and moving to the latest available driver is usually encouraged. Use Intel® Driver Update Utility to keep your system up-to-date with latest graphics drivers or manually update from downloadcenter.intel.com. To verify driver version installed on the machine, use the system analyzer tool.
- For Linux* and Windows Server*:Intel® Media Server Studio is an integrated software tools suite that includes both SDKs, plus a specific version of the driver validated with each release.
Driver Branches
Driver development uses branches covering specific hardware generations, as described in the table below. The general pattern is that each branch covers only the two latest architectures (N and N-1). This means there are two driver branches for each architecture except the newest one. Intel recommends using the most recent branch. If issues are found it is easier to get fixes for newer branches. The most recent branch has the most resources and gets the most frequent updates. Older branches/architectures get successively fewer resources and updates.
