Note on Intel® Quick Sync Video

Check and adjust the device load when dealing with transcoding pipelines. For example running the Intel® Quick Sync Video encoding might reduce benefits of using the Intel® Graphics for some OpenCL™ frame preprocessing. The reason is that the Intel® Quick Sync Video encoding already loads the Intel® Graphics units quite substantially. In some cases using the CPU device for OpenCL tasks reduces the burden and improves the overall performance. Consider experimenting to find the best solution.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
