Which PostgreSQL version are you planing to use for your tests?
Sometime back, I have done the performance test for read-write pgbench
on Power8 m/c and came to know that scalability is not good.
I am interested to see your tests results especially of HammerDB.

Power7 and Power8 m/c (Power8 is better), so testing on Power8 makes
sense.
