Yes, but you want to test on slower devices. You could still develop on a powerful machine and build you binary, but test it on the slower machine.
Got a tip for us?

PSA for Developers: Mac Mini With A12Z Chip Cannot Be Repaired at Genius Bar or Service Provider

But they’re not going to be using the A12Zs in the final release Macs. A benchmark will tell you how this iPad chip runs pre release software, but it will give you no indication of how purpose-made laptop chips would perform.
It's because these aren't close to the systems they're shipping this fall. They don't want people flipping their lid over the performance of these things when they are very explicitly an early prototype for testing your code works and not the things people will be able to buy in six months.
They don’t want people testing it and starting the whisper campaign that the thing is slow, when this thing isn’t even close to what you’ll actually be able to buy.
If intel gave you a 80286 to develop on in preparation for their eventual release of the 11th generation i9, benchmarking the 286 would be stupid. Just like benchmarking an a12z - a chip we ALL HAVE ACCES TO already. It is pointless.
"no benchmarks". That says it all. Apple wants to minimize the amount of bad press.
Basically these are iPads with keyboards. How long until the Mac Pro is discontinued and with it Final Cut X?
I would suggest technical users and professional users start looking for some other platform.
If these Arm-based CPUs performed well Apple would be putting but benchmark results themselves rather then prohibiting users from doing so.

This is A12z that we already have benchmark for it.
And since it is using the same A12x CPU on the SoC we already have benchmark for it for 2 years!
OS will not affect hardware benchmark and they are using same llvm clang compiler for both macOS and iOS.
You can get benchmark of the DTK without using DTK itself and does not even have to break any NDA today. Just Grab and 2020 iPad Pro and run your benchmark.
For me, DTK is to check if my iOS app will run on it without issue and if there's any new feature that wasn't possible on a Intel Mac.
And I have to build OpenJDK on it to test some older apps.
That's the purpose of this machine, not wasting time on some already know numbers.
They are EXACTLY ipads with keyboards. But they have NOTHING TO DO WITH THE MACHINES APPLE WILL SELL TO THE PUBLIC. These LITERALLY USE A TWO YEAR OLD IPAD PRO CPU AND GPU.
The reason they don’t want benchmarks is they don’t want people like you going around saying “Arm macs suck” when the only information they have is based on a development kit which will never be sold to the public and has a CPU that is years out-of-date.
This isn’t rocket science.
The period between the release of the 286 and the i9 was very long, so of course performance changed a lot. But the period from the release of this development system and the first retail Mac with Arm is projected to be less than a year. One year is not enough time to expect huge changes in performance. Not even a single generational change.
That said, I expect to see published benchmarks days after the development system is released.
In the end, Arm will work well for many users who do typical things like email, web browsing, Youtube, and office work. But it is the end of the line for media editing, Engineeeing and certainly for those who need virtual machines and Bootcamp. Those users will have to decide between Linux and Windows.
It’s wild to see so much terrible information in a single post.
This isn’t the chip they’re going to ship. Benchmarking it wouldn’t have any value, but it would get less informed people whipped into a panic because they dont understand that this isn’t laptop/desktop hardware.
The A12Z performs very well, but it’s a tablet chip. Apple has specifically said that they’re creating a dedicated line of chips for their computers, which will likely be more powerful and better cooled.
Take a deep breath, it’s going to be alright.

It’s not one year. It’s almost three. The a12z is the same chip as an a12x, which was released almost 2 years ago. And Apple has a history of year-over-year performance improvements of 20% or more. So even a new iPad Pro processor released in early 2021 should be more than 30 percent faster than these development kits. Now take that exact same chip and stick it in an enclosure with proper cooling, and it should fly.
I don't think this has sunk in yet with most people. Never before has anything like this been done at this scale. Soon Apple will control the entire assembly of the computer. All parts.
Computers have always been a mess of disparate components. So far it has worked, sort of. Of course they will eventually come after Apple for this.

Doing a little bit of reading (dangerous, huh). The Apple Silicon will be using RISC, while intel and AMD use CISC. RISC needs more working memory to execute each instruction per clock cycle or it will bottleneck the CPU. If this info is correct and I'm sure someone will correct me if it is not, skimping on memory with Apple Silicon may not be advised. So maybe 8MB, as a base, isn't going to be good enough anymore.
So Just How Powerful Are Apple's New Laptop Chips Gonna Be

You’ll probably be declined.
Well, other than scale it’s been done before.
Commodore made the chips in the Commodore 64. Sun designs its own chips for sparcstations. IBM designs its own chips for its workstations. DEC designed its own chips for its workstations, as did HP (PA-Risc), Silicon Graphics, etc. Even Hitachi, Fujitsu, etc.

No, that’s not true at all.
1) Arm has more registers than x86, so it doesn’t have to read or write memory nearly as often
2) RISC and CISC have no inherent difference in the amount fo RAM required.
What you may be talking about is that the number of bits needed to represent a given operation can be more for RISC than CISC since you need to account for multiple op codes. This is not a significant effect, especially in x86-64 64-bit instructions, which are less “compressed” than the 32-bit instruction formats.
Additionally, that’s just instruction memory, not data memory. And the instruction cache size is appropriately sized to accommodate that. Nobody EVER runs out of RAM because the instructions take too much space in RAM - they run of of RAM because the DATA takes too much space in RAM.

Yes, I just tried, but the cd-rom doesn’t fit.
So we can assume within a day it will be benchmarked, disassembled and all the results put on to social media.
Lol.
There was also no chance Apple could beat Blackberry in the phone market.
