Hi guys,

How are you?

I hope you can help me understand and purchase the best system for my needs, the fastest, more reliable and that continue to help me 5 years ahead without upgrades.

I learnt that real time performance is what matters so single core is more important than multi core performance? I will describe my needs so you can help me choose.

What I would like to achieve is:

Low buffer size 64/128 on my MOTU 828 MK3, so I can play in realtime several kontakt instruments( SSD, M-2), and use any plugin chain I want, even a full mastering chain on 2 bus. Ozone, eqs in linear phase mode, CPU hungry synths, plugins etc...

I am using Ableton Live 10.

A) i7-8700K with Asus Maximus x hero

B) Rizen Threadripper 1950x with ASUS Zenith Extreme

Another factor is loading of Kontakt instruments, low load times is required as well.

So producing and playback vst instruments, vst plugins, audio is what I need, don´t need to record live instruments, only midi thru a midi keyboard.

Thanks.

The performance is only as good as the slowest core, so if all the chips are running at 4GHz then one with 8 cores is better than one with 6 cores. However, 8 X 3.5GHz is probably going to hit a wall before 6 X 4GHz on a really busy project when one of the channels overload, it'll take the rest with them.

The problem comes when trying to compare Intel to AMD as they have different IPC (instructions per cycle) figures so direct comparisons regarding clock speed are fairly worthless without some kind of benchmarking.

Between those two, the raw CPU power in testing goes the 1950X but the as soon as you throw memory handling into the mix, it swings back to the 8700K. Given Kontakt is memory handling heavy, I'd lean towards the 8700K.

Kontakt load times are down to your storage subsystem, so get all of your libaries onto SSD's.

Single core performance is only important if the application cannot handle multicores!
Audio processing is the ideal application to use multiple cores (lots of calculations in parallel)
I don't know, if Live 10 isn't using the cores, I'd switch to something else, but I doubt it... Kontakt can take advantage of the cores btw, but you should leave multicore handling either to the DAW or the sampler...
AMD performance per buck is better...

It's actually more complicated than that. Modern DAWs can usually distribute workloads to multiple cores. However, on a single track with a chain of plugins, it's often not possible to split the work of the whole chain to multiple cores, because each plugin in the chain needs output from the plugin before it, thus cannot just be processed without first finishing the processing of the previous one.

Therefore, if in the song there's a track with a few heavy plugins in the chain, it might be able to play properly on a 4-core 4.0 GHz CPU but struggle on an 8-core 3.2 GHz CPU.

In general, however, if there's no track or chain with such heavy load, more CPU cores mean more tracks it can handle. People using heavy plugins should take this into account when considering a new CPU, I think.
Peace, my friends. I'm not seeking arguments here. ;)

What would be heavy plugins, linear phase eqs, what's more?

I read somewhere about too many core is not good but I really don't understand why...

Would you mind explaining this better?

I read something good about the AMD 2700x vs 8700k?

Maybe for video work , I wouldn't agree for audio.

Well, traditionally stuff like convolution reverbs as it's all floating point heavy, and that can thrash the CPU. TBH, the heaviest stuff at the moment tends to be heavily spec'd sound generators (Vengence Synth) or extremely detailed modellers (DIVA, Acustica Audio Plugs), but really it could be any type of plug-in, depending on how it's coded.

The message from Poonna above pretty much nails it. Each core can do "X" amount of work within a given time frame (the ASIO buffer cycle). If all the threads complete their workload within the allotted time, then everything is good. If 1 single thread overruns it's allotted time frame, the whole project will crackle.

Case in point for the value comment. The 8700K benches about 10% - 15% higher and costs about 10% - 15% more. Both firm are pretty well priced against each other right now and when one moves a price the other cuts accordingly. Once you get out of the realm of hardware where AMD competes, the Intel price per core creeps up slightly, but the lower to midrange kit is currently fairly equal in the bang per buck stakes.

I would wait:
For the new Intel 8 core Coffee Lake
https://wccftech.com/intel-8-core-coffe ... confirmed/
or
The new Threadripper 2
http://www.guru3d.com/news-story/amd-an ... ipper.html
If you go for Ryzen/Threadripper, seems it can benefit from faster memory with tighter
settings in some applications, choose your RAM carefully.

In the future if you ever want Thunderbolt the motherboard must be compatible, the ASUS PRIME Z370-A
is the only Z370 in the Asus line.

No working Thunderbolt for AMD yet, but the Gigabyte x399 Designare EX does have the header
