Ik kwam op de frontpage van Ace's Hardware een interessante analyse tegen van de Celeron SMP performance:
On Tom's and BXbord's test they show FSB speed is very important in the dual clelron performance as both cpus have to share the same bus. This fact also lead to the rendering benchmarks on the K bench where the PII beats the celerons by 22% in the lightwave tests, and having a better memory test score, because it needs to access the memory bus less often by having a larger cache. So basically one can see for compiling and very small multithread SMP ware programs dual celery system can work wonders. But if you has some memory intensive works to do a dual PII/III setup is still much more desirable.
So just like JC had said only a few special benchmarks such as rc5 gets a near 100% boost. One should expect about 55% gain on 3D rendering speeds and linux compiling, about 20% on compiling in VC++, about 7% for other smp aware apps, and next to nothing gain in other softwares including games. Thus the need for the dual is determined by one's own software.
Oftewel: de (vrijwel nergens meer verkrijgbare) C300A is de beste Celeron voor SMP.
