I do believe they announced the M1 last year at WWDC.
I do believe they will announce the next gen chip (M2x?) at this years WWDC. I suspect availability of the new chip will be after the iPhone 13 debut. Hope a M2x in a MBP before 2022.
I’m hoping the new MacOS will offer, performance settings.
It's been mentioned elsewhere that the M1 was announced for November Macs last year. M1 was tied closely to the A14 CPU in the iPhone 12 so you are quite right when you speculate on M2 being tied closely to the iPhone 13 (A15 CPU).
The A14 CPU, however, made its debut in the
iPad Air 4 (2020) which shipped on October 23 after being announced alongside the iPhones on September 15 last year.
The same CPU was only confirmed as being in the
iPhone 12 when Apple held a special event on October 13, after which the A14 was made available in there too.
Usually the iPhones at least would have been out in September but we can put a caveat on launches last year due to COVID but I recall the A14 being pored over closely due to the iPad Air 4 launch.
Not quite. They announced a switch to Apple Silicon without specifying any specific CPU/SoC. They did announce the DTK which used an iPad A12Z in a Mac mini case but that was just for developers to get a head start on porting their Mac software to Apple Silicon.
I they announce a new SoC it will be within 30 days or so of shipping to customers. Apple isn't one to announce products ahead of time except in very limited circumstance. The last thing they would want to do right now is convince anyone interested in the M1 Macs to wait and see what comes next (Osborne syndrome).
Typical Apple MO is to release as soon as possible after launch as per your write-up. Supply chain may still be impacted by CPU shortages and COVID delays though.
It would be a very tight release schedule if Apple were to launch the M2 CPU alongside the iPhones later this year, I believe all will be revealed around WWDC if Apple intend to release multicore Pro level gear based on the M1 architecture but with more cores.
Leaving it much later risks Apple bumping into A15-based architecture in October.
Having said that though, one small detail about the much leaked 'Pro' Macs comes along thanks to the
Qanta Ransomware leaks recently.
The high performance MacBook Pros will have 1x Magsafe, 3x Thunderbolt ports, SD card reader slot, and a HDMI port.
Assuming that each Thunderbolt port will have its own controller as with the M1 Macs then it's still a reasonable compromise, made more interesting by the removal of the Touch Bar.
So of the remaining products, if you look at the Mac mini - could we see the SD slot returning to the back of that while it gains just one single extra Thunderbolt port if Apple choose to do a high performance mini to replace the top SKU Intel mini.
True; however, the announcement that Apple is transitioning away from Intel took place at WWDC
This just gives Apple till WWDC 2022 to complete the transition (presumably with the ARM Mac Pro which without a doubt should appear at a WWDC). You'd therefore assume that if things were going according to schedule that M1, M2 CPU budget products would appear November-April with multicore variants by the WWDC after that April.
