The i7-9700K was only released last month right? I would steer clear of that, it'll be overpriced and potentially might not be supported by even the latest kernel (I can't actually find anything about it in relation to linux). Get something older and use the saved money on soundcard.
yes, you're right. This CPU is "too new" on the market.
Me too, I've found nothing related to the Linux kernel and this CPU.
I've now read a lot about the currently available PC hardware. My conclusions are:
- AMD's Ryzen and Threadripper are very powerful for everything, excepted for RT audio processing --> OUT
- Intel's core i9 is obviously not supported by the Linux kernel --> OUT
- Intel's core i7-8yyyX and i7-7yyyX are powerful but expensive and the suitable mainboards are really expensive and I need to buy an extra GPU --> OUT
- Intel's Xeon are expensive (if you want a powerful one) and their features are a bit "overkill" for an audio workstation --> OUT
- Older overclocked Intel's CPU is not an option because of stability and reliability considerations --> OUT
At the moment, best choice seems to be Intel's core i7-8yyyK or i7-7yyyK.
For example, an i7-8700K performs almost as well as an i7-7820X but the whole configuration CPU+mainboard+GPU of the K is about 200-400€ cheaper as that of the X.
Other aspects of the hardware config:
The Ferrofish Pulse 16 has only line levels inputs. OOOOTCH!
That's a problem because I have 8 mics for the drums and 1 for the vocal. It's means I have also to buy 9 microphone preamps. It becomes too expensive...
I've reconsidered the new Behringer ADA8200 (with the red front plate) because it has built-in mic preamps (with switchable phantom power) and line level inputs ON EACH CHANNEL.
I've also found this review: https://www.soundonsound.com/reviews/behringer-ultragain-ada-8200
According to the link, the unit has been really improved by Behringer:
The ADA 8200 employs different converters, the new devices being made by Cirrus, and the latency through the unit is substantially lower, measuring just 0.55ms at a 44.1kHz sample rate (compared with 1.46ms for the old ADA 8000).
I think this is only the input latency, but I'm not sure.
