Marco ArmentI'm confused about the difference between the middle “A19 Pro" and the bottom "A19”.
Still can't figure out what makes the Air's “A19 Pro" different from the 17's “A19”.
The 17 Pro's chip has a 6th GPU core, so that one makes sense. (A little.)
Oh, I think I got it.
When talking about the A19 Pro's “50% more cache” for the CPU cores, they said A19 Pro is “even faster and more efficient than A19”.
So:
17: less cache
17 and Air: more cache, 5 GPU cores
17 Pro: more cache, 6 GPU cores
I wonder if they maybe clocked them differently, too.
Max Leibman@marcoarment Yeah, I would expect there will be some down-turning to eek out battery life in the Air.
Jacob Wolman@marcoarment yeah I think the implication was the iPhone Pro thermals allow them to overclock (but they didn't say so explicitly).
Aaron@marcoarment looking forward to getting more definitive word on memory differences. I’ve heard some say all models get 12GB but a more recent rumor saying the base iPhone sticks with 8
Matt Washchuk@marcoarment Really hard to understand how the Air has a Pro chip but only USB 2 speeds.
Daphne Preston-Kendal@marcoarment Didn’t they mention something about a larger cache? I might be confusing it with one of the other times they mentioned something having a larger cache

@marcoarment its only binned Pros.
@@marcoarment when they where talking about the A19 Pro they mentioned something additional for the GPUs…some kind of accelerator? I believe they did not mention anything like this for the A19.
Matt Killmon@marcoarment My guess is it gets fewer of the low-level bumps that the Pro chip gets? So, less cache per core, maybe fewer ML-accelerating features in the GPU cores?
EDIT: Oh no, I guess they call out the ML stuff specifically for all. Can't read.
@marcoarment ohhh no, I’m wrong, the accelerators are in the A19 as well, my bad. No difference then.

Nate Smith@marcoarment Something related to USB 2 vs USB 3?
David Freeman@marcoarment GPU cores
Jordan Cosentino@marcoarment I believe the Air has a disabled GPU core.
mohdislamsh@marcoarment what app is this ?
Reemt@marcoarment and I’m trying to see the point behind having an C1X and an N1 in the same device, both doing something with wireless data transmission.
Jonathan Trott@Reemt @marcoarment C1X is for cellular, N1 is wifi, bluetooth, and thread
@jonathantrott @marcoarment does it make sense to keep these radios in different chips? Seems a bit odd to me.
@Reemt @marcoarment yep, I'm sure they will be combined in the future to further reduce space and power usage.
@Reemt @jonathantrott Radio chips have all sorts of analog components in addition to their digital computation. I bet there are good reasons.
Cellular modems are also REALLY complicated and relatively large, so maybe it made sense to fab the C-series on a more expensive leading node than the probably-much-simpler N-series.
@marcoarment @jonathantrott I just realized that we‘ll likely see N-series in everything from Macs to HomePods and Apple TVs soon, while C-series will obviously stay in cellular enabled devices.
Anton Leuski@marcoarment I believe they have GPU cores with additional neural network acceleration (or some such) in the Pro version.
Jough@marcoarment Also is the SOC for the Pro and Air the same aside from binning the GPU cores?
Jason R. Heimbaugh@marcoarment Design isn’t how something works. It’s what we name it.
