• 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 V
ector 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
• R
ecompile 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
-oper
ate with existing Intel SSE
libraries.

Dynamic Power technology (Memory Power Management) is a platform feature
with the ability to transition memory components into various low power states based
on workload requirements. The processor platform supports Dynamic CKE (hardware
assisted) and Memory Self Refresh (software assisted). For further details refer to the
ACPI Specifications for Memory Power Management document.
