This is pretty cool to see Server on ARM chips, let alone on an SOC. (System On a Chip)  I also did not realize to what scale some of these ARM SOC’s had as mentioned in the quote:

Qualcomm and Cavium have both designed motherboards for the Project Olympus form factor that use ARM chips: Qualcomm’s Centriq 2400 processor, a 10nm 48 core part, and Cavium’s ThunderX2 ARMv8-A, with up to 54 cores. In addition to offering lots of cores, both are highly integrated systems-on-chips with PCIe, SATA, and tens of gigabits of Ethernet all integrated.
