Actually, that is not true at all. Handling two threads at once, no matter what they are can greatly improve performance.
"The P4 performs the test in 82 seconds and the Athlon in 71 seconds. But a dual PIII is a different story. The response time is a blistering 50 seconds, or 39 percent faster than a P4, achieved by the extra cache of the two processors."
It doesn't matter if the applications support it or not. If the OS supports it, then the system will be able to take on two threads instead of one. If it does that then there will be two FIFO ques in the system instead of one. Meaning two applications can be given CPU time at once.
For instance if you are playing HALO. Halo will get all the attention it needs via one CPU, whilst the OS processes get the attention they need via the other.
If you do a search on SMP and how it works many sites will tell you this.
Run this bench, let me know what you get:
If you only have one CPU, you can only do one thread.. That will show you the diff between one CPU and two..
