Based on an IWOCL 2017 tutorial Unlock Intel GPUs for High Performance Compute, Media and Computer Vision.
Intel provides many extensions to the Khronos OpenCL™ standard to help you utilize the full range of hardware capabilities.
These extensions are not standalone. They build upon each other.
The tutorial code focuses on subgroups, VME, and VEBox. Image processing and sharing extensions are also used in the tutorials code as solution components.

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.
