rPerf is a computer benchmark that evaluates the relative OLTP performance of servers based on IBM POWER microprocessors. It is published by IBM and derived from a model based on specific workloads, plus benchmarks from Transaction Processing Performance Council and SPEC.

What is POWER8 and POWER9?

By definition, POWER8 is a 22nm process option. POWER9, on the other hand, is a 14nm process option. POWER8 L1 caches can fare 64 + 23 KBs for individual cores, while POWER9 L2 caches can manage 32 + 32 KBs. Note that POWER8 L2 caches can accommodate 512 KBs for each core.

What is IBM p770?

The IBM 9117 Power 770 model MMD server is a symmetric multiprocessing (SMP), rack-mounted server.
