*So this isn't POWER8 or POWER9
*Two clusters of CP chips connect to the SC. Can connect four drawers together
*CP and SC are large chips, 17 layer metal in 14nm SOI
*10 cores has private 2MB L2-i and 4MB L2-D and 128 MB shared L3
*New translation and TLB design over z13, and general pipeline optimations.
*5.2 GHz, super long pipeline
*8 cycle L2 hit latency (that's only 1.5 ns) ...
*Execute 2 AES in 3 cycles
*New GCM instruction
