Agreed, upon closer look, I don't see 250,000 where I think it should appear in elsewhere in the detailed report...looks like shoddy auditing...which makes me question the validity of any of these benchmarks from Oracle.

I think I understand that. But explain if you can chances you can get a result that ends in 5 or more zeros! It doesn't mention any rounding, it only mentions extrapolations which is quasi weasel words for guessing in my book.

Workload POWER7 3.3GHz Xeon 5570 2.93 Ghz
Payroll Processing 1,161,290 1,395,349
Prepayments 4,500,000 1,052,632
External Archive 423,529 468,750
NACHA 18,000,000 20,000,000
Checkwriter 4,500,000 2,727,273
Costing 6,000,000 7,500,000

Both servers appear to have questionable results. The difference is that results that appear to be actual measurements. The Xeon beats the POWER...not by much mind you. And with 8 physical cores instead of 6. But it appears that the POWER benchmark had SMT enabled and the Xeon didn't. All around these two benchmarks seems to be a mess.
