Overview
The chip has been designed by Qualcomm specifically for the data center. Specifically this architecture is an attempt to address high concurrency, high thread density while maintaining isolation and quality of service between the processes. The overall chip consists of 24 core duplexes incorporating 48 cores on a ring interconnect along with 6 channels of DDR4 and L3 cache distributed across the ring. The chip also integrates 32 PCIe 3.0 lanes, 8 SATA gen 3.0 lanes, and a mixture of various other I/O peripherals.
