First of all, it is not fair to compare my two systems. The AMD was a mid-speed computer in 2000/2001, however, you can compare them to similar systems.
First up, my laptop with the following important specs:
1.6GHz Pentium M w/2MB L2 cache overclocked to 2.13GHz via pinmod
2,048MB (2GB) of PC4200 DDR2 RAM
533MHz FSB
Now my desktop:
1.4GHz Athlon Thunderbird (last of the non PR rated CPUs)
1,024MB (1GB) of PC3200 DDR RAM
266MHz FSB
You can compare the results of each to the following setups:
Laptop:
Supposedly a ~2.0GHz Pentium M is faster than a 3.2GHz Pentium 4 with HT disabled. So you could compare this to an Athlon that is PR rated at "3200" I suppose.
Desktop:
The first PR rated Athlons was the Athlon XP "1800" 1.5GHz. So I suppose you could compare my 1.4GHz T-bird to a 1.7GHz Pentium 4.
Oh, and I forgot to mention, supposedly Pentium Ms are horrible with floating point calculations, so I had better see some Athlon "3200"s beating my laptop!
