Unfortunately without -S, you're not really testing the processors. A regular pgbench can fluctuate a more than that due to writing and checkpoints.
For what it's worth, our X5675's perform about 40-50% better with HT enabled. Not the 2x you might expect by doubling the amount of "processors", but it definitely didn't make things worse.
