It's fairly easy to understand why Apple will transition to their own ARM-based CPUs. Multiple factors are involved.
I think the chief factor is Intel has been moving way too slow and stubbornly conservative with its own CPU development. The company acts almost like a cartel of sorts, strong-arming vendors into using its arguably obsolescent designs as opposed to taking a chance on newer designs from rivals, like AMD and its acclaimed Ryzen CPU. I don't know what's going on in back room "negotiations" between Intel and companies like
Dell, HP and others. The Ryzen CPU has gotten a lot of raves, but it's still not appearing in a lot of desktop and notebook PC product lines.
The glacier-pace of development has turned certain Intel products into
a complete waste of money. The notebook version of their Core i9 CPU is a primary case in point. The Core i9 consumes too much power and runs hotter than lava, especially in a thin notebook chassis like a Mac Book Pro or a
Dell XPS. The very high priced CPU throttles way down to very sub-par performance levels to save it from cooking itself to death. The 2020 versions of
Dell's 15" and 17" XPS notebooks don't even have an i9 option available currently. Even the latest 8-core i7 CPUs generate a lot of heat and can have throttling issues.
Obviously Apple doesn't need any of that garbage. Apple already has a lot of experience developing ARM-based devices and software (for iPhone and
iPad). This move simplifies things for them.
The move will probably improve their profit margins and/or allow them to sell Macs at more competitive prices.
Still, I have very mixed feelings about the move. Apple still plans on selling Intel-based Macs for a couple more years, but I predict the sales levels of those kinds of devices to go right into the toilet. Who in their right mind would want to buy a pricey Mac notebook with an Intel-based CPU if Apple is going to stop supporting it in the future?
Ditching x86-based CPU architecture means no more ability to run a
Windows partition and
Windows-based apps natively on Apple hardware. That's going to force people who've been using Mac hardware to run PC apps into a tough choice. When they buy a new
computer they'll either have to switch to an ARM-based Mac ecosystem or they'll have to ditch the Apple-branded hardware for something else that runs
Windows natively. It's too bad Apple couldn't have tried making a Ryzen-based Mac.
The software used in the
sign industry
is extremely Windows-specific. Very little (if any at all) runs native under OSX. And now there's going to be Intel and ARM-based variants of OSX for a couple of years. I certainly do not expect developers such as SAi to create two different versions of Flexi to run on OSX when they're not even making an Intel-based version for OSX now.
CorelDRAW is a more "mainstream" graphics application. The company has been struggling to get their current OSX variant up to snuff. Do they have the resources to develop ARM-based and Intel-based versions of CorelDRAW for OSX? Adobe is already at work porting their applications, but they're a big company with a lot of resources. Serif kind of has a head start since they have
iPad versions of Affinity Designer and Photo.
