Prefer Buffers over Images

On the Intel® Architecture processors, device buffers usually perform better than images, as buffers provide more data per read and write operations for buffers with much lower latency. The reason is that images are software-emulated on the CPU device. So, if your legacy code uses images or depends on image-specific formats, choose the fastest interpolation mode that suffices your needs, for example:
  • Nearest-neighbor filtering, which works well for most interpolating kernels
  • Linear filtering, which might decrease the CPU device performance
If your algorithm does not require linear data interpolation, consider using buffers instead of images.

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.
