The 2020 Mac Mini Unleashed: Putting Apple Silicon M1 To The Test
by Andrei Frumusanu on November 17, 2020 9:00 AM ESTConclusion & First Impressions
Today’s piece was less of a review on the new Mac mini as it was testing out Apple’s new M1 chip. We’ve had very little time with the device but hopefully were able to manage to showcase the key aspects of the new chip, and boy, it’s impressive.
For years now we’ve seen Apple’s custom CPU microarchitecture in A-series phone SoCs post impressive and repeated performance jumps generation after generation, and it today’s new Apple Silicon devices are essentially the culmination of the inevitable trajectory that Apple has been on.
In terms of power, the Apple M1 inside of the new Mac mini fills up a thermal budget up to around 20-24W from the SoC side. This is still clearly a low-power design, and Apple takes advantage of that to implement it into machines such as the now fan-less Macbook Air. We haven’t had opportunity to test that device yet, but we expect the same peak performance, although with more heavy throttling once the SoC saturates the heat dissipation of that design.
In the new Macbook Pro, we expect the M1 to showcase similar, if not identical performance to what we’ve seen on the new Mac mini. Frankly, I suspect Apple could have down-sized the Mini, although we don’t exactly now the internal layout of the piece as we weren’t allowed to disassemble it.
The performance of the new M1 in this “maximum performance” design with a small fan is outstandingly good. The M1 undisputedly outperforms the core performance of everything Intel has to offer, and battles it with AMD’s new Zen3, winning some, losing some. And in the mobile space in particular, there doesn’t seem to be an equivalent in either ST or MT performance – at least within the same power budgets.
What’s really important for the general public and Apple’s success is the fact that the performance of the M1 doesn’t feel any different than if you were using a very high-end Intel or AMD CPU. Apple achieving this in-house with their own design is a paradigm shift, and in the future will allow them to achieve a certain level of software-hardware vertical integration that just hasn’t been seen before and isn’t achieved yet by anybody else.
The software side of things already look good on day 1 due to Apple’s Rosetta2. Whilst the software doesn’t offer the best the hardware can offer, with time, as developers migrate their applications to native Apple Silicon support, the ecosystem will flourish. And in the meantime, the M1 is fast enough that it can absorb the performance hit from Rosetta2 and still deliver solid performance for all but the most CPU-critical x86 applications.
For developers, the Apple Silicon Macs also represent the very first full-fledged Arm machines on the market that have few-to-no compromises. This is a massive boost not just for Apple, but for the larger Arm ecosystem and the growing Arm cloud-computing business.
Overall, Apple hit it out of the park with the M1.

@Kangal - I have a few disagreements with what you've written here.Firstly, I'm a little confused about why you see the Rosetta-based benchmarks as most relevant. I doubt that anyone buying an M1 device today will be getting rid of it before the majority of apps are converted across, so that performance is going to become increasingly *less* relevant as time passes.
Secondly, this quote: "In short, Apple played it safe and didn't really do their best. That means they purposely left performance on the table, it was artificial and it was deliberate." - I just don't see how you could draw that conclusion. They used their highest-performing cores in the largest chip yet produced on 5nm. It would be bizarre for them to begin such a grand experiment from the top-down - it would produce an odd situation where their most demanding users, who are most likely to be using applications that currently need translation, would be expected to transition to an incomplete ecosystem with performance that doesn't exceed existing systems.
To me, it makes perfect sense from both an engineering and a product perspective. They begin the transition with a relatively small (and thus high-yielding, despite the new process) chip as part of a platform for users who are relatively performance-insensitive, but who will still appreciate the immediate benefits of reduced heat and increased battery life.
I'm also a bit confused about your perspective on their GPU. AFAIK the most modern low-profile low-power GPU out there is Nvidia's 1650 - and in terms of performance-per-watt, this iGPU thrashes it, with absolute performance being not far behind. Perf/Watt appears to be Apple's primary concern (for a given degree of absolute performance), so I see it as a resounding (and surprising) success. It's down to AMD and Nvidia to respond now.

@SpunjjiThanks for the read, sorry it's quite long.
I mean, the Apple Silicon M1 as it is, it's very good for the new Macbook Air. I guess for the cheap/budget Mac Mini it is also decent. However, it's kind of out of place on the Pro. Perhaps they will launch more Macs in the next 6 months, something beefy for their larger MacBook Pro, and maybe something desktop-worthy in an iMac and Mac Pro. I completely agree with your points. Apple now has the best chipset in the world, their large cores are highly competitive, and their GPU tech is the most efficient. In fact, their medium-cores are the best, they're an Out-of-order processor which sucks slightly less power than a Cortex A53 (or slightly more than A55 ?), but they're slightly faster than a Cortex A73 (or slightly slower than A72 ?). Either way, that's stupidly impressive.
But as it stands, Apple has done the works but on the last yard, pulled its punches.... and I state that since they're saving money on the SoC by sourcing it themselves, and not paying those exorbitant Intel prices. So there's definitely (money and silicon) budget there to go more ambitious. I just wanted to see more competitive/better product segmentation, eg:
Apple M10, ~10W, 8 large cores, 8cu GPU... for 11in laptop, ultra thin, fanless
Apple M13, ~15W, 8 large cores, 16cu GPU... for 14in laptop, thin, active cooled
Apple M15, ~25W, 8 large cores, 32cu GPU... for 17in laptop, thick, active cooled
Apple M17, ~45W, 16 large cores, 32cu GPU... for 29in iMac, thick, AC power
Apple M19, ~95W, 16 large cores, 64cu GPU.... for Mac Pro, desktop, strong cooling
...and after 1.5 years, they can move unto the next refined architecture/node (ex Apple M20, M23, M25, M27, M29 etc etc).

I believe the iPad Pros (if not all iPads) will move to the M1 chip and run the MacOS with the ability to run iPadOS/iOS Apps. With the detachable keyboards and Apple Pen support - they will become the ultimate Portable workstation. Knowing Apple's penchant for a limited product line - they may even drop the Apple Macbook Air.BushLin - Saturday, November 21, 2020 - link
"To be honest, a lot of comparisons of the Apple Silicon M1 are vague, misrepresentative or blatantly off..."<proceeds to list unattributed benchmark results with incorrect power labels>

@vlad24 - I'm aware of how process node can affect voltage requirements and power draw, and the various TDP differences.I wasn't arguing that TSMC 5nm wouldn't help AMD's power efficiency, I was arguing with the nonsensical statement that it's the *sole reason* for Apple's good showing in that area. lilmoe's salty opinions aren't supported by the facts.
You're correct that AMD at 5nm would probably regain an advantage over M1 in mobile devices, but that will be in a year's time, and Apple aren't standing still. It's likely we'll be seeing them leapfrog each other. In the meantime, it'll be interesting to see how competitive Cezanne ends up being with M1 and/or whatever Apple's next-largest chip will end up being.

But if shrinking Zen 3 to the same 5nm process would make its mobile variant more energy efficient, then that would imply that Zen 3 is a more efficient architecture. It just happens that the architecture is held back in this specific comparison by the manufacturing process.We do not know if AMD will bother to port Zen 3 to 5nm, they could skip straight to Zen 4. Who knows what process Apple will be using by the time AMD moves to 5nm. 3nm could still be too expensive for chips larger than those used for phones.
Granted if the energy efficiency of Zen 3 equals M1 when both are on 5nm, then the M1's efficiency cannot be solely due to 5nm unless that were also true for Zen 3.

Zen 4 is scheduled to have samples Q1 2021 on 5nm advanced node TSMC. The fact you don't know this tells me you don't follow AMD.Spunjji - Monday, November 23, 2020 - link
@mdriftmeyer - You'd be wrong in both assuming that I don't know and that I don't "follow AMD". Samples in Q1 2021 does not equal released product in Q1 2021, does it? I'm talking about product availability, and you're moving the goalposts for reasons that aren't clear to me.magreen - Tuesday, November 24, 2020 - link
@Spunjji - Thanks for your insightful responses, as usual. Sometimes I'm tempted to just hit Ctrl-F to find your comments and ignore the rest.haghands - Tuesday, November 17, 2020 - link
