Apple iMac Pro 8-core or 10-core for PT 2019?
 
Hello fellows,

As a musician (keyboarder/composer) I am working on an iMac 27 i7 4.0 ghz (late 2015), armed with PT 2018.12.

In my compositions I make heavy use of U-He Diva, Soundtoys, izotope and Omnisphere and I am facing a lot of CPU-overload errors (not surprisingly). Most of the time i freeze or commit the tracks, although, the fan of my imac is regularly running wild (around 2400 rpm). This is annoying.

My idea is to do a major change soon and switch to an imac pro 10-core with 64 gb ram. Despite the fact that pro tools does not officially support mojave yet, is there anyone using such an imac, atm with another daw and willing to share his experiences? what do you suggest, 10-core or 8-core?

Thanks.

Regards

Hi, I have a 10 Core iMac Pro with 128GB ram with Pro Tools 2018.12. Doesn’t give a breeze with protools.

However, when using plugins like LFO tool on your Instrument Tracks, it’s still better to freeze them because protools doesn’t handle some parts of delay compensation of MIDI/VI’s correctly.

Aside from that, iMac Pro is a killer machine.

I went for the 8-core because it has a higher clock frequency, which for they way I use PT is more useful than a higher core count.
My Hackintosh however still smokes this machine, even though it's 2 years old and cost me a quarter of the iMac Pro. :o

Great machine indeed. I thought the imac pro has to run mojave as os? did not know that a "downgrade" is possible.

But I bought it december 2017 when high Sierra was the most current OS still.

I don’t have experience with running pro tools 2018.12 on Mojave on my iMac Pro. But a Mojave compatible release should be out within some weeks from now.
I do run 2018.12 on my MacBook Pro 2018 i9 which is running okay apart from some GUI glitches. But I don’t use it heavily like on my iMac Pro so can’t tell how it performs with big sessions under Mojave. Definitely the lower than 256 sample buffer is still an issue on Mojave, like with 10.13.6 till pro tools 2018.12 fixed it.

Correct, the 8-core has a base clock of 3.2 ghz with turbo boost up to 4.2 ghz, whereas the 10-core has 3.0 ghz and turbo boost up to 4.5 ghz BUT pro tools benefits from every core, and so plugins, especially diva with multi-threading option.

To my understanding this will have the effect that 10 cores, although at a lower base clock but with higher turbo boost, will speed up realtime processing and "relax" the overall cpu-load because of a higher count of cores?

Is there a big misunderstanding on my side?

Thanks

Depends on your sessions. If you have longer bus chains load isn't distributed among several cores, because it's not possible. Each link of the chain has to be processed before audio can get passed further down, so not much can be parallelized, at least for me. If you work with lots of VIs and other stuff a higher core count is beneficial.
For me even with 8 cores I see a lot of boredom in the CPU meter across cores and not a great amount of distribution. One core does most of the work.
It's very different from working with video for example, where every core is maxed out when rendering.
The $ I saved not getting the 10-core I invested in the Vega 64 and more RAM, since you're stuck with whatever you're choosing forever. And I figured I rather have headroom in that regard, than two more cores that chill on the couch most of the time.

I did a quick test with my i7 late 2015 imac and opened a blank 24bit/44.1khz session with dozen tracks of u-he diva loaded. The system usage shows that all 8 available units of my quad-core i7 have been used equally until reaching the total red zone. No core was in chill mode :)

So, having a 10-core (20 available units for math tasks) make sense in such a scenario or is the xeon-architecture something different with respect to pro tools?
All in all, you are true, if your session does not need many cores, more ram and a better gpu make more sense than a 10-core.

Hello,

I am currently using the iMac Pro 8 core with Pro Tools 2018.12 and SUPER heavy on plugins you can check my list here:

Honestly, I was a fan of always updating the OS to the latest one and running into bugs back since 2001 ....

It's the first time I am running a super stable System knock on wood but thin is I am running High Sierra 10.13.6 and I will never ever update ?

Think again ... why would you wanna update to Mojave ?
