KVR Audio

I am building a new high end system. I ordered a Ryzen 2990WX (32 core, 64 thread) but I think I will send it back when it arrives. I was linked to these reviews which indicate glitchy performance of these Ryzen processors on high load or low latency which defeats the purpose:

http://www.scanproaudio.info/2017/08/14 ... 20x-1950x/

So then that leaves the new Intel processors. It looks like the i9-9980XE will be the top CPU on the market once it becomes publicly available in the next week or two. From the links above, it looks like the Intel processors hold up much better on low latency which is ideal.

I require as much power as possible as I do additive synthesis with my own synths I've written and they are very CPU intensive. I like low latency because it allows more "real time" feeling for recording and playback performances.

Is the i9-9980XE likely king of the mountain?

Probably not. Few sequencers seem to be load balance efficiently above 32 cores and you're taking an IPC hit on the larger core count processors. I'd be tempted to take a 14 or 16 core with higher per core clock speed, over a slower one with a higher core count, and that's we even begin to think about bang per buck ratios at that end of the range.

Probably one of the new Skylake-X Refresh will be.

That may not matter. Especially if you are managing high CPU plugins. With very high CPU plugin chains, you may want to disable hyperthreading anyway, and then you are down to 18 extremely powerful threads on the i9-9980XE.

Obviously it's not about bang per buck at that point, but rather just that if you're running very intense processes and don't want to have to freeze and unfreeze every track every time you make a change, I think this is the most powerful CPU possible and best suited for the job.

Likely I will disable hyperthreading for this reason if I get it.

Well, that's one way of doing it, can't disagree with the thought process through.

Best CPU in existence - Intel i9-9980xe? (vs. AMD Ryzen)
