    more core vs more speed

    Hi dear MC users. I'm just starting to learn AVID MC and I need help. if it's not hard for you, advise me which option is better for editing in Avid MC in 4k: macbook pro with 16Gb Ram and 6-core 2,2 GHz i7 or iMac Quad-Core i7 3,6 GHz with 16Gb Ram ?

    Re: more core vs more speed

    I believe higher clock speed benefits NLE over core count.

    I think more cores have better long term value.

    Re: more core vs more speed

    I would look at this article, which attempts to break down how Media Composer uses computer hardware.

    Re: more core vs more speed

    As long as you have "enough" cores then speed over quantity every time for MC.

    Its not the same for all NLE systems but certainly its been the case with MC for many years.

    As core count goes up the max CPU speed tends to lower. For many MC functions splitting the task over many cores is less efficient than hammerimg a limited number of cores.SO its hogh CPU GHz for me. But it has to be quad core or more.

    A dozen cores is good 24 is a waste

    Re: more core vs more speed

    fact: rendering in avid is much slower than it should be.  This really needs to be improved.

    They qualify these high end pc's and at the end of the day, Media Composer does not use this hardware efficiently when rendering.

     

    Transcoding and ama export, is another story. I give them an a+ for that, although there should be a web quality version at the ama export speed.

     

    I don't think there is one machine for all uses.  If you want a transcoding station, get as many cores as possible.  If you want an every day editor thats rendering often, you want a higher clockspeed since multicore use is dismal on MOST fx with rendering.

     

    And if youre working on long form, a 14 core, will export the timeline 2 times faster, that a 6 core (compensating clock speed) exporting really does use all of the cores.  Same with transcoding, double the speed.

    Re: more core vs more speed

    Defiantly the imac

    i had a 2014 quad core 2.7 ghz mackbook Pro i7 and a 2015 imac about 4.0 or so ghz before and now I have a 4.2 ghz 2017 imac with 8gb Gfx card and 40 gb ram and it is sooo much better. Everything is so much faster.

    i do a lot of long form , over an hour ,often cuts are 2 hours when rough and getting them out for preview needs to be efficient.

    i can get h264 renders at 133 fps using third party encoders.

    Recently I did a job with split screen (40 min) where I used resizes luma keys ani matt keys colour correction etc,all stacked up and it would play without needing to render.

    The other issue is having a big screen.

    Re: more core vs more speed

    its also worth mentioning that from last year, intel's consumer cpu's went from 4 to 6 to 8 cores (next month) (thanks to amd).

    My hope is that all developers starting making use of this mainstream tech *cough* mc rendering.

    Re: more core vs more speed

    must say that HP z240 with Intel i7 7700K 4,2 ghz is much bang for bucks!

    for example; exporting a 44 min sequence to MXF, dnxHD120 in 15 mins! (with AMA File export)

    44 mins MXF to h264 in Adobe Media Encoder, 12 mins..
