When I was in charge of DriverHeaven I wrote a scripted benchmark which was not only used to help users ascertain system specific performance levels but was useful in reviews to accurately measure performance in key areas. Leading tech sites such as Madshrimps, Hardware Canucks, Benchmark Reviews and Hardocp used my benchmark in their reviews also.
This version of the script has been thoroughly tested on Adobe Photoshop CS5 and CS4 and is compatible with Photoshop 7. It is important to document however that different versions of Photoshop give different end results. Adobe have been fine tuning the program over the years and enhancing specific filters and algorithms for better performance (some filters were rewritten during the CS2 time period). This means ultimately that comparing times with users running other versions of Photoshop is not going to give consistent results.
All results were gained from Adobe Photoshop CS5 64bit exe on Windows 7 64 bit ultimate.

The results show how horribly inefficient Adobe Photoshop is with multiple cores, still favouring clock speed over multithreaded performance. We had hoped with CS5 they would finally have rectified this situation but sadly not. The 875K at 4.8ghz has produced the highest ever score in our benchmark suite, by a considerable margin.
