Processor Features

The Intel Xeon Skylake Scalable family is the next generation core architecture with improved Instructions per Cycle (IPC) and other
architectural improvements. The Intel Xeon Skylake Scalable family features are as follows:
• Virtual address space of 48 bits and a physical address space of 46 bits.
• Intel Hyper-Threading Technology (Intel® HT Technology) when enabled allow each core to support two threads.
• First Level Cache (FLC) 64 KB total. The FLC is comprised of a 32 KB ICU (Instruction Cache) and 32 KB DCU (Data Cache).
• MB Mid-Level Cache (MLC) per core (non-inclusive with the LLC).
• Intel® Advanced Vector Extensions 512 (Intel® AVX-512) with a single AVX512 fused multiply add (FMA) execution units. SKUs which
support Advanced RAS enable a 2nd FMA execution unit.
