Those sites are now quite dated but some data may be useful but things like data storage have change so dramtically with SSD's and the newer super speed M.2 PCIe x4 SSD's that what took 5+ hard disk drives in Harms era now can be done with 1, 2, or 3 of the M.2 PCIe x4 SSD's . My partner, Harm Millaard, in this Premiere Pro testing who passed away 20 months ago designed such a complex web site that I found no way I could keep it updated. Newer test data is now on Premiere Pro BenchMark (PPBM)
This benchmark is four tests using basic Premiere Pro to stress test the CPU, GPU, and the storage system. It is not a media test as it was designed by Harm and myself in the CS5.5 and CS 6 era and without any modifications runs today on Premiere 12.
