PowerMac G4 stress test

This is a video showing the multitasking capabilities of the Apple workstation based on PowerPC G4 CPUs. Built in 2002/2003, it was the last of the G4 series, later replaced by the more performance G5. The program that records screen activity requires a lot of resources and a large part of these are absorbed by this one. Nonetheless, the Mac manages to handle the huge workload very well by slowing down but NEVER crashing.

That is very impressive, I guess I never have the G4 enough credit.

The PowerMac G4 - Tagline: 'Everything you want to do only slower'

OSx Leopard has excellent credit, which has improved the Powermac's capabilities. And I have to tell you that on the 2.7 GHz Dual G5 with 6Gb of ram with a 1350Mhz bus (On the G4 it is a 167Mhz bus !!!), it does not enjoy the same responsiveness despite being faster. Surely the 3rd level cache present in the G4 (well 2Mb per CPU is a huge deal, while on the G5 there is only the 2nd level 512Kb per cpu) makes that miracle of multitasking possible.
