I agree. I recorded 8 channel multitrack from Pd to Ardour using a single core Thinkpad back in the day with no drop outs.
You could try running Pd with a different nice level. Even though it has "realtime priority" it sometimes helps to cue the scheduler a little more directly.

Interestingly, setting CPU scaling governor to performance is not enough for Pd (it is for other applications, though). When doing that for each core, they all run at maximum speed. However, it doesn't help with making Pd glitch free. I really have to put some load on them.
This confirms what I suspected for while now: The advanced power saving features of modern CPUs don't really help for realtime audio.
I wonder what softwares like Ardour do differently to not fall victim of aggressive power saving.
Having a constantly running fan is also not an ideal situation. I don't care about increased power consumption at this point. Maybe there is a less invasive way to keep the CPU busy?
