Benchmarking Comparison: HP Pavilion tx2051 and tx2525

I ran some benchmarks on the two HP units I have (the tx2051 and the tx2525), and the results were kind of surprising.   I kind of thought there would be a little bit of a difference, but some things didn’t make sense…   Take for instance the HDD.   Both units have the 250GB 5400 RPM drive, but take a look at the difference.   Almost makes me wonder if the these test are really providing good results.   Below I have the critical specs for the test listed for each unit and the benchmarks below that.   Take a look and let us know what you think.
