Quite a lot of testing in Final Cut and Logic etc showing very good performance and efficient swap. So for most consumer apps it works well. No magic if you need a big block of memory for ML or analytics.

Do we know what benefit they're getting by putting the memory on the chip to begin with? I had initially assumed there was some non-trivial performance advantage in it, but now people are saying not so much, so why did they do it?

It seems weird to artificially limit the max memory if there was no advantage in it.

I think it's a power advantage, not performance.

The benefit is they can charge you $200 for memory they bought from Samsung for $15. There’s no performance advantage to the user.

I’d love to know where you’re picking up LPDDR4X-4266 RAM for $15?

Are you actually asking? The spot price for LPDDR4X 16G is only $9. I was actually being generous. No doubt the contract price is far lower.

Yeah a link would be good. I haven’t seen anything approaching those prices - all well over $100
