    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.

    Actually that answers my question I posted here pretty well.

    Though I am more interested in the difference between 2.8ghz quad and 8 core doing a huge amount of raw files. If your results were to hold I would be able to convert my batches in something around a little less than an hour to one and a half hours. Pretty stunning when it takes two and a half to three and a half hours on the laptop i'm working on and six to nine hours on the desktop at work.

    When I was doing the tests I had activity monitor on and I could see that when converting the raws the image processing parts were split pretty much evenly across all 8 cores but they weren't at maximum. However, all the other bits and pieces the machine has to do during the processing where not spilt - hence only an approx 30% gain.

    But for folks not processing raws and just using the basic photoshop on normal size images, from what I could see, there is virtually no significant improvement from either the extra cores or extra speed of the new computer's processors, bus or memory.
