Thanks for this.
The graphic means that the MacBook and an entry-level iMac will have integrated GPU on the Apple Silicon SoC (same as current A-series). There will also be a high-spec iMac with some kind of additional or different GPU architecture (Lifuka). It may be a separate chiplet on the same SoC package, or a discrete GPU, or even just a more powerful integrated GPU.
ah, sorry, by ”old” i thought you mean pre-big Sur, which didn’t make any sense.

In this session Apple shows you can do reduced security mode to boot older version of macOS.
By old I mean "old in the future" that is still Big Sur and later.
This just officially confirmed running macOS is still not tethered to apple's signing server unlike iOS right now.
But the larger package required to support the much higher thermal envelope will have plenty of room for more (and faster) IO pins.
I agree. My guess is that performance will be "somewhat better" than Intel CPUs that it replaces, but with much better GPU power and very good battery life (>15 hours).
Oh dear, you really need to do some research!
From what I’ve read MacMini Intels have had heat throttling that knocks down their performance. If the ARMs can beat the Intel‘s performance why not use them in everything, including the MacMini.

Same here. There are risks associated with a brand new physical design, with the added uncertainly of first-generation MacOS-on-ARM and potential immaturity of 3rd-party native software or Rosetta 2 short-comings.
But is may not be discrete in the sense we understand today. It's possible that it will be a separate module (chiplet) on the same SoC package because it needs to share memory with the CPU cores. It's possible that Apple has developed a new kind of bus between SoC and a truly discrete GPU, but it would need to be *much* faster than PCIe if it going to share memory.
Price drop? You’ve got to be kidding....they’ll probably jack the price up.
i think Apple would offer it officially.
apple.com says you can buy a 21.5" with only Intel Iris Plus 640 integrated GPU.
Errr...kind of. Yes, Windows on ARM exists but there is not much native software for it. Until very recently only 32-bit x86 software ran under emulation...very slowly. MS announced 64-bit support, but I expect it will take at least a couple of years before performance is acceptable. Emulated games will suck. Native games will take some time to appear, if ever.
Even if you take this prediction into account that you are going to be surprised
93-octane? You can't even buy fuel that low in many countries. My small Skoda requires a minimum of 95-octane (RON95) and I usually run 98-octane. I bet a Ferrari would run sub-optimally with only 93-octane. I have read that US fuel is often low-octane. Maybe the standards differ?
Me too. Got the $1799 version for $1579 and it works great.
Different. Europe uses RON, US uses (R+M)/2. US 91 is like Europe 95.
Question is how easily that limit can be changed. Maybe there is a single constant defined in the operating system which decides the maximum number of cores, and that number can be changed from 64 to 128 or 256 or something bigger. Maybe someone decided "we will never have more than 64 cores, so we don't need to change this" and that limit is built into many places. We don't know. But with 56 virtual cores available in actual machines today, I would have given someone the task to make this changeable a while ago.
