Ars Technica heeft een artikel in elkaar gedraaid waar wat uitleg wordt gegeven over Dual Celeron systemen, zoals o.a. Eric van Fastgraphics die in elkaar geknutseld heeft.
To understand what's going on here, you need to know a little bit about dual-processor systems. When you've got two processors, one of the main issues you have to work out is who gets control of the bus and when (this issue is called bus arbitration). Back in the 386 days, when you only had one processor on the bus calling the shots, bus arbitration wasn't an issue. The old Intel CPUs had a bus request pin (BREQ#) that would go low when the CPU needed the bus, and that's all you needed to worry about. In today's world, things are a bit more complicated.
