Technologies
• Power Efficiency - Intel AVX is extremely power efficient. Combined with the high
performance that it can deliver, applications that lend themselves heavily to using
Intel AVX can be much more energy efficient and realize a higher performance-per-
watt.
• Extensibility - Intel AVX has built-in extensibility for the future vector extensions:
— OS context management for vector-widths beyond 256 bits is streamlined.
— Efficient instruction encoding allows unlimited functional enhancements:
• Vector width support beyond 256 bits
• 256-bit Vector Integer processing
• Additional computational and/or data manipulation primitives.
• Compatibility - Intel AVX is backward compatible with previous ISA extensions
including Intel SSE4:
— Existing Intel® SSE applications/library can:
• Run unmodified and benefit from processor enhancements
• Recompile existing Intel® SSE intrinsic using compilers that generate
Intel AVX code
• Inter-operate with library ported to Intel AVX
— Applications compiled with Intel AVX can inter-operate with existing Intel
SSE libraries.
