Old Mac Pro 12 core- Faster Capture One than i7?

Nik Mills
I'd like to optimize the Capture One Experience.

I use a 15" 2014 MBP 2.5 i7 QUAD / 16 RAM / SSD. It works okay with Capture One.
But there's a little overall delay here and there.

Question:

Would a 2010 3.43 12-core, also with an SSD and 16 RAM (or more) and Radeon 5770 be noticeably faster? I understand C1 uses all cores, but does the i7 trump those cores? Any tests done with these older towers vs. new CPUs?
Love to know before I buy.

Thanks.

    I went from a Mini i7 to a 2012 Pro Six Core.
    Two SSD's.One for my systems files and catalogs such as Capture One, Lightroom, Media Pro,and Photo Supreme and the other for photos. Both mounted on a single card in the PCI Express slot.
    24 GB memory and a 7950 Video Card
    My reason was because of lackluster catalog performance. The Pro didn't help much in that regard.
    The normal rendering,adjusting, etc seemed smoother. Was it worth the cost difference? I'd say not.
    However the additional inside storage and ability to add more memory (I just ordered two 8gb sticks to replace two 4gb sticks) did take the sting out.
    Plus, it has no problem running LR,C1, and Photoshop CC at the same time. And I can listen to my online tunes as well.
    I really wish Apple didn't drop their towers, that is one amazing unit.
    There's my .02

    Some of the Phase One software engineers may have to weight in to get the true picture.

    It's hard for me to say what the bottleneck in the performance is and for what type of performance. Core CPU speed, multiple cores, amount of RAM, GPU capability, and storage interface speed must all be playing some part.

    Does a fast i7 trump a slower, but 12-core, system? Often it does. But maybe the GPU is even more important. And you can hardly go wrong with SSDs on a fast interface.

    That's the most concrete information I am aware of:

    The following outlines the softwares demand;
    • Preview Update with different settings, styles etc: RAM ( I assume live experience when editing )
    • Sorting/Rating: CPU cores and SSD speed ( I assume for all catalog (database) work )
    • Fit Image to Screen: GPU cores
    • Process time: GPU processing units and CPU's and RAM

    Excempt from here:


    Note, GPU is only utilizing its full power (OPENCL) when graphics card has 2 GB memory or more.

    Thank you for your replies. When I upgrade my system I'll report my findings.

    The 12 core CPU will likely be faster for processing (using CPU only) and preview (if your are using Nikon, Canon or Phase One/Mamiya). The 5770 GPU will likely be little slower than a brand new MBP in processing (using GPU).

    Whether or not CPU will be used instead of GPU for preview also depends on the camera maker? Or does the number of CPU cores (or processors) depend on the camera?

    To some extent. Only Fuji Xtrans based cameras cannot use the OpenCL.
    Currently Nikon, Canon and Phase One/Mamiya/Leaf models can use multiple cores to decode the raw-files (with the exception of sraw/mraw options). All others are single-core.

    I am planning to buy a new system.

    Heck, this is valuable information! I didn't think there are differences at least not for Bayer based sensors.


    I use Sony (Nikon and Olympus (though em10 mkii not supported yet)). If C1 only uses a single core then 6 or more cores would be wasted investment, wouldn't it (for preview update and processing)?

    But wait, when I heavily play with the tools (Sony ARW), and also when I out-process images, Task Manager shows 100% and all 4 threads show the same CPU "usage curve" (dual core with HT, i5 520M, gfx card underspecced). How does this observation fits into the equation?
    C1 8.3.3

    Can you please advise?

    Thanks in advance

    Remember it is only the decode part (loading the raw file bayer info from disk into the ram) that with a Sony file is a single core operation. Most other operations in CO are not vendor dependent, and thus use all cores available.

    Regarding buying a new CPU, then also look into how fast the seperate cores are, and the amount of cache. For CO use, I would also recommend getting an i7 over a an i5. Beasically buy as much power as you can afford.

    Thank you Christian,

    This explains it...
    so I can look for multiple cores even for Sony cameras 😊)
    I was actually looking to buy a used one-generation-back workstation, i.e. 1x or 2x Xeon 6Core E5-2620 with 15 MB Cache but only 2 GHz (2.5 GHz turbo) and 1333 RAM.
    Maybe a i7 would be better, not decided yet.

    Thanks a lot and have a nice weekend

    Hi again,

    The architecture (generation) of the Xeons always seem to be lagging behind the i7s (i.e. Skylake Xeons are supposed to be coming in 2017?)

    However, Mac Pros seem to use the Xeons for quite a few generations, right? So, there must be some reason behind....

    My current choice for a new computer is now

    Intel Xeon E5-1650v3 3.50GHz 15MB 2133 6Core CPU
    32GB DDR4-2133 (4x8GB) RegRAM
    1 SSD on Sata III (I can upgrade later to a PCIe SSD)

    I intentionally left out the graphics card in the discussion, as this can be replaced/upgraded later. I do want a usable performance even without GPU hardware acceleration!

    This is going to be a HP workstation.
    (I know this is a Mac Forum but the posts are much more to the point than in my thread "workstation recommendation please" )

    Would this be a better (or equal) choice over a 5th or 6th generation i7, e.g. in a gaming PC?
    Will this workstation satisfy me over the next 4 years with upcoming C1 releases?
    Will it run smoothly with 36-50 MPix resolution images?
    Will it run smoothly with 40.000 images in a catalog?

    Thanks and cheers
