A few days ago I posted a thread asking if anyone had any 'raw' image processing stats comparing the old 2.66 4 core against the new 2.8 8 core. No one posted a reply so I took a CD with 10 raw image down to the London apple store and used one of their 2.8 8 core machines (I've got a 2.66 4 core machine) for the comparison. The following are the results of the 3 tests (mirroring my workflow - apart from I'm normally processing 100's of images) that I carried out on the 10 image files (from a Canon 1Ds MkIII): Converting the 10 raws to jpgs: old MP 53 seconds, new MP 42 seconds Opening the 10 resulting jpgs: old MP 13 seconds, new MP 12 seconds Applying an action that opened each jpg, applied an adjustment and then re-saved the image: old MP 29 seconds, new MP 28 seconds. Both machines had 4 Gig of memory and worked of the main disk. Just thought I'd post the results in case anyone else found them useful.
