First of all, those 2 CPUs are vastly different.
Second, There are a hundred reasons that one box will be faster than another.
Third, your two systems couldn't be more dissimilar. So your comparison is Apples vs. Elephants! You have different memory, cache, also, it is not easy to compare AMD speeds to Pentium speeds. Although, I have found that AMD are typically faster for the SAME "rated", (ie. 500MHz 1.0GHz) speeds on the exact SAME HARDWARE.
