[SOLVED] Cpu for 32 bit float/192khz music production

[cortyb]

I currently have an i9-9900k which is relatively good for music but it chokes at the highest sample rate and bit depth in my daw (32 bit/192 khz), and yes i'm well aware of "why would you need such high sample rate it's pointless" blah blah blah. Really I'm just looking for a solid answer or recommendation for a cpu capable of handling the highest sample rate and bit depth, I'm currently eyeing the i9-7980xe, but is there any confirmation this will do the job?

I really don't see this upgrade helping. Your current rig should be more than sufficient.

What are the specs for the rest of your system and what apps are you using for your audio needs?

Heres all of it
Mobo-gigabyte aorus ultra
ram- g skill ripjaws 32 gb 3600 mhz
gpu-evga hybrid rtx 2080 ti
psu- EVGA SuperNOVA 1000 T2, 80+ TITANIUM 1000W, Fully Modular
soundcard- creative blaster ae-5

apps- fl studio and studio one

Have you adjusted your app settings in an attempt to optimize performance?

Yes they are completely optimized, highest buffer setting, got all my plugins through buses, etc. but cpu still reaches over 100% when I do the most minimal work.

Just to understand how your rig is performing, if you lower your sampling rate, does performance improve?

Are your editing apps fully current/up to date or are you using older versions of the apps?

 

[cortyb]

Yes they are both up to date and lower the sampling rate and bit depth does help improve drastically.

Do you have Hyperthreading enabled or disabled in your BIOS? Does changing make a difference?

I just enabled it and opened a heavy task load in my daw and no difference.

I don't see more cores/threads as the solution, so I wouldn't recommend a change in the CPU/mobo. Additional memory (bump rig up to 64GB) might help, as this seems more of a memory issue than CPU horsepower.

Techreport does DAW bench testing. Maybe this helps?

Seems cores/threads offers an advantage for Intel, coupled with clock speeds according to that, and the 7980xe would fare even better with some OC against the 9900k. Although there's got to be another factor here since the gains OC shows for a 9700k and 9700k OC are none to minimal, so it's something in the differences between lga1151 and lga2066 that really allows the daw to use cpu abilities. What that test did show was the 9900k using 16Gb dual channel, but did not show if the XE's were using that 32Gb 4x8Gb in 2x dual or quad channel setup, so apart from double the memory, does the daw soak enough bandwidth to get good use from a quad channel vrs similar ram in dual channel.
