iOS - Sampled or modeled sounds?

Looking at this from a purely processor P.O.V., which method is "better" for the iPad in terms of use and performance? Even battery life?

afaik, modeled instruments rely pretty much on the processor, thereby, I imagine, hampering additional CPU workload, which would equate to less access to other sounds/instruments.

Whereas sampled instruments would use less CPU, and re;y more on streaming from storage, yes? Thereby allowing a greater number of instruments to be accessed at one time.

Or, do I have that whole concept wrong?

It depends if the sampler implements disk streaming or not. From what I have learned, not all iOS sampler apps actually use disk streaming.

But, I think you’re right that modeling is more CPU intensive. Sampling would use more RAM, unless it utilizes disk streaming.

BeatMaker3 uses disk streaming. It seems like Gospel Musicians apps like Pure Synth Platinum use disk streaming for the sampled instruments as well.

AudioLayer, BeatHawk and most of the standalone piano instruments that are sample-based use disk streaming and are lighter on CPU use than modeled instruments that are doing realistic modeling (like SWAM and PianoTeq).

Thanks, yes that confirms what I was thinking.
