There's just no denying the Intel processors' dominance in this Photoshop test. The 45nm ones are especially potent, as the Core 2 Duo E8500's third-place finish indicates.
The Panorama Factory photo stitching
The Panorama Factory handles an increasingly popular image processing task: joining together multiple images to create a wide-aspect panorama. This task can require lots of memory and can be computationally intensive, so The Panorama Factory comes in a 64-bit version that's multithreaded. I asked it to join four pictures, each eight megapixels, into a glorious panorama of the interior of Damage Labs. The program's timer function captures the amount of time needed to perform each stage of the panorama creation process. I've also added up the total operation time to give us an overall measure of performance.
This application uses four and even eight cores quite well. Nonetheless, the Core 2 Duo E8500 is nipping at the heels of the Phenom X4 9750, amazingly enough. Still, the Phenoms perform well for their price range.
picCOLOR image analysis
picCOLOR was created by Dr. Reinert H. G. Müller of the FIBUS Institute. This isn't Photoshop; picCOLOR's image analysis capabilities can be used for scientific applications like particle flow analysis. Dr. Müller has supplied us with new revisions of his program for some time now, all the while optimizing picCOLOR for new advances in CPU technology, including MMX, SSE2, and Hyper-Threading. Naturally, he's ported picCOLOR to 64 bits, so we can test performance with the x86-64 ISA. Eight of the 12 functions in the test are multithreaded, and in this latest revision, five of those eight functions use four threads.
Scores in picCOLOR, by the way, are indexed against a single-processor Pentium III 1 GHz system, so that a score of 4.14 works out to 4.14 times the performance of the reference machine.
Some of picCOLOR's functions use four threads, yet the E8400 and E8500 outperform the Q6600, as well as both new Phenoms.
