Why is my (Emachine T6536 desktop) better than my (Dell Precision m4400 laptop)?

People just simply do not understand computers that well. I have older computers that run faster than new computers. It all boils down to the architect of the motherboard, not what is installed hardware wise and also affected by the software installed. Windows can be fast on one computer and slow on another. Not much can be done to make two computers run just as fast as each other, there are too many variables involved and very difficult to track down what is behind what is happening. You could get hundreds of answers, yet not a single one of them would make both computers run the same. It just isn't possible. You could even have two identical computers, yet one would run faster than the other. They both have different Processors, one is AMD and the other is Intel, that does make a difference.
