A little understanding

[Mad Max]

I am new here to the forum but have been tinkering with Thinkpads for quite some time. I have an interesting question to put out to the forum. I currently own two machines, a G40 & a T30. The G40 has a 2.8 P4 running 1 gig of memory and a 60 gig hard drive. The T30 has been upgraded from a 1.9 to a 2.4 P4M and has 512 of memory and a 100 gig hard drive. My curiosity comes from the fact that the T30 will spank the G40 in benchmarking almost every time? I run PC Mark 2002 as this is from roughly their time and they can handle the tests. Why does the G40 seem to lag behind the T30? I thought newer machine, faster processor, more memory, it should handle the T30 no problem. Any thoughts?
