Testing benchmark of fused multiply-add routines currently developed in context of LSP Project.
The results of benchmark I've compared to one of my computers with AMD Athlon 64 X2 4400+ CPU.
It seems that Raspberry Pi is already faster than x86 processors issued in 2005's.

The results of Raspberry Pi 4, ARMv7 (32-bit) operating system:

Re: Raspberry PI 4 vs AMD Athlon 64 X2 4400+

Postby tavasti » Thu Nov 21, 2019 8:19 pm

So PI4 would be better option than old laptop(s) I have (I have also recent HW). But availability of software makes things different, no Mixbus available. Is there even arm port of Ardour?

Anyway, thanks for benchmarks!

The main disadvantage of PI is that it does not have SATA or M2 support out the stock.
Banana PI's are more interesting but a bit less powerful than PI 4.

Yes.

As for storage, Pi4 has USB3 which should be fast enough for streaming at least a few tracks over.
