The StrangeMaze 3D benchmark
"In the PC world the buying customer is given important information about the PC: the microprocessor (e.g. Intel Pentium 4), the speed of the microprocessor (e.g. 2GHz), as well as a whole range of other specifications. These specifications help the customer make an informed choice, they give the customer an idea of the relative performance of one PC compared to another, and more importantly they give the customer an idea of how fast software applications will run on a particular PC.
Unfortunately this is not the case if you are buying a Java mobile phone. The customer generally does not know what processor is running inside the phone, what speed the processor is running at, how fast is the Java implementation and therefore the customer cannot get an idea of how fast Java games will run on a particular phone."
