Intelprocessor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across
different processor families, go to: Learn About Intel® Processor Numbers.
Intel® Advanced Vector Extensions (Intel® AVX)1 are designed to achieve higher throughput to certain integer and floating point operations. Due
to varying processor power characteristics,utilizing AVX instructions may cause a) some parts to operate at less than the rated frequency and b)
some parts with Intel® Turbo Boost Technology 2.0 to not achieve any or maximum turbo frequencies. Performance varies depending on
hardware, software, and system configuration and you should consult your system manufacturer for more information.
