Re: Dual Xeon Scalable LGA 3647 workstation. Anyone?

You made a great remark on minimum base clock speed. That is key. Otherwise you can have 1000 cores and not be able to run a single instance of a heavy VI. And it is great to have the idea of what this minimum is: 3GHz. So, in short, I should get the highest number of cores (even dual processor) while not going below 3GHZ base frequency and, if doable, slightly overclocking the processors with adequate cooling. My remark goes to the cost. The Intel Core-X series has a much better price/performance ratio. The Xeon Scalable (LGA 3647) is around 30% more expensive for comparable performance - although you can have a ˜50% more powerful single system if fully expanded. But then VEP can be used past the single Core-X system capability. Also, in general the base frequency of the Xeon Scalable is lower and it is really not overclockable (you can fine tune some parameters of the ASUS WS C621E SAGE motherboard but it is not really overclocking as we know it). So, the final conclusion: best system is a set of as many as required Intel Core-X (i9-7940x or i9-7960x), LGA 2066,slightly overclocked, a high speed network 10Gbps(?), Pro Tools on one machine and VEP on the "slaves". Am I correct? And what about the best motherboard for this job? What would you recommend? |

I do know that a couple of the pro daw builders are currently using asus boards whereas they used to use gigabyte. I never seem to find any info regarding msi boards and daw setups. Again, no one seems to be answering whether 10GB ethernet is providing and real world latency improvement for VE Pro.. i also investigated this and can't get concrete answers.. Hell, i can't even find an answer for how much live playing latency a slave ve pro will have..well i realise the default is a 2x multiple of main interface latency but what is actually *usable* over ethernet? Is anyone successfully using it with the latency multiplier at 0 so the slave machine has the same real time latency as the primary? I have no idea..i have scoured the VSL forums.. there's just patches of info here and there. Personally, for just two machines directly connected, i am sure gigabit is enough and that's what most use anyway as what was "standard" on most boards. If you are talking multiple slaves, you need a network hub and in that case it's possible 10 gigabit will make a difference in performance.. it won't make a difference in the latency figures as VE Pro slaves work at a multiple of your main interface latency on the main (pro tools) machine, but maybe 10 gigabit will be able to stream it more consistently without clicks or pops.. Again I just don't know, and personally i will never go beyond the scope of two directly connected machines.. Yes, two intel core x systems would be insanely powerful, and if you don't need thunderbolt and want to save money, two threadripper 2 machines would also be insanely powerful. Or an intel main one and threadripper slave.. I am just thinking of that 32 core 3.2ghz chip with 4.2ghz turbo.. that's 32 cores and 64 threads, the 2990wx i believe. You can open multiple instances of VE Pro on the slave machine and use ALL of those 64 threads.. it's crazy when you think about it, 32 real cores at 3.2ghz is over 100 gigahertz on one chip LOL! Personally if i was doing a dedicated twin pc setup, i would get intel skylake X on my main, a 7940X with good cooling at a permanent 4ghz clock with turbo disabled, just one stable clock speed at all times, all intel throttling disabled via bios, and a threadripper2 32 core slave dedicated to VE Pro. But that's me. YMMV... To tell you the truth if i didn't have a thunderbolt interface i'd just get two threadripper systems and save cash. One thing that is still valid today that the audio boards all seem to forget is that AMD chips are less susceptible to denormal spikes.. intel still suffers from this with many plugins.. most are coded properly but any dev can miss just one thing that will cause spikes under certain usage scenarios.

Re: Dual Xeon Scalable LGA 3647 workstation. Anyone?
I think this is in the area of what I want to move to when I build another daw. ASRock has a dual thunderbolt 3 card too.

Asrock, i have honestly not heard the greatest things about them at some audio boards, like, you get what you pay for kind of thing.. But who knows... let us know how it goes if you don't mind.

Re: Dual Xeon Scalable LGA 3647 workstation. Anyone?
Hi! Thank you so much to everyone that replied!
I just want to update the thread. I have decided to stay within the Mac universe for now and wait a bit for the new Mac Pro next year. For now I will use an iMac 5k 27 inch 2017 just to hold on and will use a couple other Macs as slaves. I am still considering building slave PCs with i9-7940x (x299), but as my main machine, I really want it to be a Mac OS computer for composing. I want to focus on my music as much as I can and the Mac OS really helps me on that. |

Re: Dual Xeon Scalable LGA 3647 workstation. Anyone?
Well, yet another update for this thread.
I returned the iMac Pro as it didn't work for me at all, sadly. The i5 on it just wasn't up to the task. I ordered a MacBook Pro i7 2.6GHz 6-core 16GB RAM and 512GB SSD. But then, one day before it was supposed to arrive at the store I cancelled after consulting the Mac thread of the DUC. Now I am getting the MacBook Pro i9 2.9GHz 6-core 32GB RAM 1TB SSD. Hopefully this will do it for now. I thought about the iMac Pro (more or less the same price) but buying it now in 2018 wasn't recommended because a new one will come next month (or October) and as I plan to change it to a 2019 Mac Pro I figured the MacBook 2018 would hold its value better. Also, the performance for the iMac Pro 8-core and the MacBook Pro 2018 i9 are very similar - and in fact the MacBook is better on some tasks, like h.264 decoding/enconding. |
