Well I stopped believing the manufatures specs decades ago and only really believe what I can see from experience. A new iMac outperforms a year old PC by about 12%.
I am not interested in what Intel, AMD, Motorola, Apple or articles say. This is what I see. Lightwave on the PC and Lightwave on the iMac.
The iMac speeded up as new versions of Lightwave and OSX came out. So the performace of Amiga OS will hopefully demonstrate the true potential of todays CPUs.
