Best hardware

Andre Kedl
Hello,

This question is for the PhaseOne staff.

I just wanted to know what's more important using C1?

More RAM?
Bigger CPU?
Fast Hard drive?

Thanks!

    Hello,

    Faster CPU will give you faster processing times. Its pretty much a direct relationship in performance. If you have a dual core system processing a file in 30 seconds, you may see 15 seconds with a quad core.

    Faster Hard drive will help with file writing speeds which can aid tethered shooting performance.

    Ram does not make nearly as much of a difference so long as you have a good amount to begin with. In other words, going from 4 gigs to 8 gigs on a tower will not make a big difference in most cases. Generally you will not see C1 using more than a gig of ram at a time.

    Hello,

    Jon, are your timing accurate? If they are I just might change all my computers

    because if : 2 cores = 30secs and 4 cores = 15secs then 8 cores shoud be 7.5secs

    is that correct?

    Just for curiosity. in you example, what type of file are you processing? P45 IIQ L to 100% CMYK TIFF 8bits?

    Thanks

    Oliver,

    Just quick numbers for demonstration purposes, HOWEVER I will say that a P45 8bit Till at 100% will process in just under 15 seconds on a Quad 3.0 Xeon Mac PRO from a year ago. I haven't tested the new generation Penryn Xeons yet, or the 8 cores, but I think 7.5 seconds was a pretty good bet. Of course the time needed to write the file to disk does not change.

    So do I understand it correctly, that the processor speed, RAM, do not effect the capture speed tethered or downloading cards? does it have an effect on how quickly you see the previews? I normally shot a P25+ tethered to a MBP (2.4 HGz Intel Core 2 Duo with 3 Gig RAM) and they insisted I shoot into a MacPro (No spec given!) because they thought the capture and preview speed was much faster? They require no processing, so I am wondering if anyone has any speed tests on this sort of thing? I am also curious about download speed from a Card.

    8 core with 8GB RAM and 10K RPM Raptor RAID 0 drives = 6 or 7 seconds process time with P45+ 8 bit Tiff images.

    so we all know that the process speed is faster on a higher spec machine, but what I am really curious about is does a faster machine actually speed up the capture and preview speed?

    Hello,

    Capture speed is most affected by hard drives, however a 7200 rmp drive will keep up pretty well with the buffer on IIQ files, though a faster RAID setup will generally run a little smoother. Older backs shooting Raw 3.0 files will benefit more from faster drives. Preview speed will be a little quicker and focus speed will definitely be faster with faster processors, however the change is not nearly as drastic as processing speed is because the system is doing so much more.

    So in regard to Capture / Preview speed, would you say there any any great difference from a MBP 2.4 with 3 Gig RAM, 7200rpm HD,
    to a Mac pro 2.8GHz Quad-Core Intel Xeon (8-core) with 4 gig RAM and 7200rpm HD. ? do you have any numbers to show this difference?
    What about the difference between being tethered and uploaded cards , should there be a difference between the two systems above ?

    Hello,

    good discussion here !!!
    How can we accelerate the creation of the preview and the histogram ?
    Because since 3.7.4, shooting is faster but not preview processing !!!

    What is the speed difference between the tricked out mac book pro and a Mac pro???

    Thx
