It doesn’t “basically” mean that, it means that lol!
Or are you saying all the prior work on the A-series chips had literally nothing to do with the M-class?!
It was an absolute no-brainer! And it was Jobs plan all along! He hated Intel. Working with them was torture fir the guy. He was publicly vocal back when they joined forces in 2006. By 2008 he would rail against them in his keynotes and grew ever frustrated over their lack of progress, innovation and supply. Citing constant shortages that held back upgrades.
I don’t know how old you are, but when Apple released their first Intel Macbook, they were getting refreshes every 6-9 months. Cook put a stop to that real quick, letting hardware languish for years! At one point the iMac was faster than the Mac Pro.
In 2008, Steve was still bringing out Intel’s CEO at MacWorld and even happily promoting new GPUs with Invidia.
And under Tim Cook, the MacBook Pros were updated in June 2012, February 2013, October 2013, July 2015, March and May 2015, October 2016, June 2017, July 2018, May 2019, November 2019, May 2020…
That’s on average once every nine months.
Even now we frequently get multiple updates to Mac computers in a year, look at 2023, where the MacBook Pros were updated twice, once in January and once in October.
Steve absolutely never railed against Intel in his Keynotes, he was only ever complimentary towards the company, after the transition announcement in June 2005.
In fact, apparently, even as late as 2010, Steve was having conversations with people at Intel about future iPhone and iPads, possibly including Intel chips, and even the first generation Apple TV used an Intel chip.
Relations between Apple and Intel only started to break down after the 2015 and 2016 MacBook’s, this has been well documented, Steve had absolutely nothing to do with that.
And as I said, Apple didn’t even ship their first in-house CPU until 2012, and their first in-house GPU until 2017. The A4 and A5 chips were Samsung CPUs and power VR GPUs, not even close to the completely Apple designed CPU and Apple designed GPU that is in the M series.
Please stop creating myths.
