Let’s start with the conclusion.
Final conclusion: The Atom is handling better multiple tasks, it manages to distribute its tasks to all of its cores. It can handle multiple requests simultaneously and this makes it more functional. While the P4 is faster per clock speed, it can work only on one task at a time, where the processor dedicates all of its resources. When a new task arrives it simply discards it or delays it, while the ATOM can process multiple requests at once the P4 cannot. When the load was higher the ATOM outperformed the Pentium 4 almost 100% of the time. The MySQL performance difference was also very clear in that the ATOM outperformed the Pentium 4 several times over.
