just versions of the a18 where all the parts work and i think eventually in the presentation apple made it clear that is not the case they obviously share a ton but a the a18 is not just a a18 pro with parts that don't work as far as anyone has been able to tell now maybe when they cut these things open we'll see i guess it's conceivable they could be but there's so there are enough differences that i think that can't possibly be true

Well, that's not the thing that puts it over the edge. So here, let me list the differences. What does the A18 Pro have over the A18? On the CPU side, it's got, yes, larger caches. And there you can go, okay, well, maybe they're just like some of the cache RAM is turned off or whatever. Probably not the way it does because the quote unquote, you know, SRAM that's on the SoCs is very expensive and-

complicated and that's not the they usually don't disable portions of but whatever next generation ml accelerators we talked about this before these are instructions like arm instructions for doing media type things that they're saying are only on the a18 pro

instructions the ability to execute instructions the execution units for them the ability to decode and execute those instructions is not a thing that you tend to like oh it didn't there's some part of this cpu didn't work so we'll just disable those instructions like it's not a separate unit this is part of the cpu this makes me think

The CPU cores are literally different between the A18 Pro and A18. Now, again, you could have them just disabled in software, you know, in like firmware or whatever, just like blow some fuses or whatever. That is technically possible. I'm not saying it's technically impossible, but I don't think it's anything that Apple has ever done.

And then the GPU, which is what was making people suspect things, 6-core instead of 5-core. Oh, it's easy just when one of the GPU cores is bad or whatever. But then we get to this whole section, which is ProRes video encoding, new image signal processor, and USB 3. That's a lot of chip real estate to be shipping in the A18 just turned off. Because the A18 has none of those things, right?

You know, and because they're Pro features. if this is really the same chip with huge sections of it turned off and special features that disable parts of the SRAM caches on the chip and also disable the ML acceleration instructions, even though they work perfectly fine because I don't think that's the type of thing where you get bad yields and you get them turned off, right?

I think these are two different.

chips that because of all this stuff there if it was just one or two of these things you could think about it because there's so much these are two different chips we'll find out when someone gets them slices off the top and looks at a picture of them you'll be able to see because this is stuff you can see like the pro res video encoder the image signal processor and the usb3 thing you'll be able to see where they are that's enough real estate where you'll be able to say

are these blocks on the a18 or are they only on the a18 pro either way well you know we'll find out but i have to say like the differentiation of like what makes us a pro chip versus non-pro chip i think they did it exactly right because if you look at these features and you're like i don't care about any of these that shows that you don't care about the pro features pro is like a lot of them using it as a video camera pro is video the faster speeds yes it's a shame that the 16 still has incredibly slow speeds or whatever hopefully that will come to the 16 eventually but like

They put pro features on here. And yes, if you want the fastest game performance, you have to get the pro phone, yada, yada. What else is new, right? By the way, we didn't talk about this before, but...
