Upgrading 2018 iPad Pro - looking for a gauge on how much better CPU/DSP will be
My daughter needs an iPad and I'm thinking of giving her my 2018 iPad Pro and getting a new one for myself.
I get a lot of DSP max messages in AUM with 6 or so tracks and I am just trying to gauge how far things have come since 2018.
Open to recommendations on what to get and looking for opinion, thoughts, experiences on what you can do on a new iPad vs a 2018 iPad Pro.
Any/All comments appreciated :-)

I went to an M1 Air from a 2014 Air2 - it was night and day. I have noticed that some devs seem to be notching up the power needs of their apps of late and I think that anyone without at least an M1 will be really struggling to use many of the new apps soon. I really would recommend you update your iPad, you definitely won't regret the extra umpff!
M-series SOCs represent a huge jump from the A-series SOCs that came before. My M1 iPad Pro is still a beast, and when I replace it I expect it will be because the battery is dead or the screen is broken, not because I need more CPU. So yes, upgrade. But have a look at Apple's refurb store if your budget is tight. Any M-series iPad will be a big step up. Try to go for 1TB or more of storage, which gets you 16GB RAM as part of the deal.
Geekbench has benchmarks.
What buffer size are you using?
To give you a real life, un scientific idea. I replaced a 2017 pro with a M2 pro.
I loaded Buttersynth with one of the most ressources hungry patch playing a sustained pad. I duplicated the track until I started hearing crackling.
In Zenbeats (single core)
2017 : 4 instances
M2 : 8 instances
In Cubasis 3 (multi core)
2017 : 8 instances
M2 : around 20, I can't remember the exact number.
This extra power is at the expense of the battery life. When you use music apps the battery goes empty way faster than my 6 years old battery in my 2017 iPad did.
@espiegel123 In AUM is was set to 128 frames 2.67ms @ 48 Hz. That's pretty low! I don't recall the last time I set that, but I notice it is global. So I wonder if some other app changed it? I can probably get away with 512 as I mostly use sequencers rather than play stuff. Switching to 512 more than halved the DSP %!!
Thanks for the feedback guys!
