Thread: Catalyst Perfomance

  1. #1

    Catalyst Perfomance

    Hi, I'm wondering if anyone cares to share the maximum number of HD their Catalyst machine can run. Please share your Mac Pro Specs as well.

    Here's mine:
    2009 single 2.9GHz Quad-Core Intel Xeon "Nehalem" processor
    8Gb ram
    ATI Radeon HD 4870 512MB
    256GB SSD OCZ
    Max Layers of HD1080p: 2 Layers

    Is this what I should expect out of my Quad Core machine or is there something that I didn't do right to get more layers?

    What codec and frame rate are you using?

    With some AIC 'stock content' at 1920x1080 25fps and an OCZ Vertex SSD, I have been able to run 3-4 layers on pretty much any Mac Pro with updated graphics card from 2007-2010

    However, It all depends upon the content codec and frame rate....

    Hi Simon,

    do you mean you are able to run 3-4 layers of AIC 1080p content on either quad core or 8 core machine?

    Yes - but it depends upon the content, codec and frame rate, SSD, Graphics card, OS, hardware revision

    (...if the sun is shining... whether the day of the week has a W in it...)
    Seriously: - there can be a lot of factors that affect performance - this is why no-one commits to actual results.

    You have to test with the system you have available and as close to the real content as possible.

    I;ve achieved these results on my stock of MacPros (ranging from 2007-2010) with my HD stock content... it will probably differ slightly on yours

    Now, all makes sense to me now. Thanks Simon.

    We have some quad cores - with ATI 1900 ( Tiger ) and some eight cores with 8800 ( leopard ) Strangly, but the Tiger can run 4 layers of 1080p AIC and the Eight cores, 3 layers... sometimes 4.
    Just as an example,... we had a event wich the movies are BLACK and WHITE, and we achived 5 layers of 1080p... so all depends on the content.

    with 2009 macs you should be able to get 6-8 layers of 1080p with AIC codec

    i get 6-8 layers on my 2009 8 core 2.26Ghz mac with AIC 1080p 25fps

    2009 macs with 10.6.x are significantly faster than 2008 with 10.5.x

    around 20-40% faster

    with 10.6.x more cores have improved performance - more cores are better.

    10.6.x and 2009 macs are significantly faster than the ones before

    the processors are hyperthreaded - meaning the cores are split in 2- and 8 cores appears as 16 processes-

    and 10.6.x uses all the cores to playback movies - it splits playback properly across all available processors

    even on low end 2009 machine i get 6-8 layers

    for most layers you need to use apple intermediate codec-

    for best quality people use apple pro res ( which comes in 5 flavours )

    depends on what people want-

    there is significant performance difference between codecs - and data rates
