The 2020 Mac Mini Unleashed: Putting Apple Silicon M1 To The Test
by Andrei Frumusanu on November 17, 2020 9:00 AM ESTSPEC2017 - Multi-Core Performance
While we knew that the Apple M1 would do extremely well in single-threaded performance, the design’s strengths are also in its power-efficiency which should directly translate to exceptionally good multi-threaded performance in power limited designs. We noted that although Apple doesn’t really publish any TDP figure, we estimate that the M1 here in the Mac mini behaves like a 20-24W TDP chip.
We’re including Intel’s newest Tiger Lake system with an i7-1185G7 at 28W, an AMD Ryzen 7 4800U at 15W, and a Ryzen 9 4900HS at 35W as comparison points. It’s to be noted that the actual power consumption of these devices should exceed that of their advertised TDPs, as it doesn’t account for DRAM or VRMs.
In SPECint2017 rate, the Apple M1 battles with AMD’s chipsets, with the results differing depending on the workload, sometimes winning, sometimes losing.
In the fp2017 rate results, we see similar results, with the Apple M1 battling it out with AMD’s higher-end laptop chip, able to beat the lower TDP part and clearly stay ahead of Intel’s design.
In the overall multi-core scores, the Apple M1 is extremely impressive. On integer workloads, it still seems that AMD’s more recent Renoir-based designs beat the M1 in performance, but only in the integer workloads and at a notably higher TDP and power consumption.
Apple’s lead against Intel’s Tiger Lake SoC at 28W here is indisputable, and shows the reason as to why Apple chose to abandon their long-term silicon partner of 15 years. The M1 not only beats the best Intel has to offer in this market-segment, but does so at less power.
I also included multi-threaded scores of the M1 when ignoring the 4 efficiency cores of the system. Here although it’s an “8-core” design, the heterogeneous nature of the CPUs means that performance is lop-sided towards the big cores. That doesn’t mean that the efficiency cores are absolutely weak: Using them still increases total throughput by 20-33%, depending on the workload, favouring compute-heavy tasks.
Overall, Apple doesn’t just deliver a viable silicon alternative to AMD and Intel, but actually something that’s well outperforms them both in absolute performance as well as power efficiency. Naturally, in higher power-level, higher-core count systems, the M1 can’t keep up to AMD and Intel designs, but that’s something Apple likely will want to address with subsequent designs in that category over the next 2 years.

@halo37253 I suspect you're largely correct based on what we're seeing in the benchmarks here.Of course, the answer to why Apple would do it is clear: they love vertical integration. They'll eventually be able to translate this into power/performance advantages that will be difficult to assail with apps written specifically for their platform.

Apple will have to modify their future M1s to accomodate PCIe because a large portion of the Audio Video Professional world needs it--in fact we all rely on DMA over PCI for Thunderbolt to reduce latency, and nothing like throwing away a $5k-$25k stack of Audio Interface, Mic Pres and more just because Apple wants to drop that, or just simply dump Apple and move back to Windows and deal with DLLs. I hate Windows but I sure as hell won't drop expensive gear tied with Dante Ethernet and TB3 interfacing with various Audio Interfaces and rack mount hardware because Apple thinks the Pro market only needed the Mac Pro one off before dropping us off a cliff.No one in the world of Professional Music uses Logic Pro stock plugins and the average track has any where between 80-200 channel strips to manage one mix. If you think the M1 or its predecessors with this type of tightly joined unified memory system will satisfy people are just not familiar to how many resources making professional music or film production require.
Let's not even talk about 3D Modeling for F/X in Films or full blown PIXAR style film shorts, never mind full length motion pictures. Working in 8k and soon 16k film to have real-time scrubbing will demand new versions of the Mac Pro's Afterburner and upgraded Xeons [or if they were smart, Zens] but definitely not M series SoCs.

@mrdriftmeyer - I don't see that any of the requirements you've mentioned here would preclude Apple producing an M1 successor that would be capable of fulfilling them. In particular you mentioned 8K video scrubbing, which the M1 can already do better than the average Xeon. I doubt they'd throw away the audio market entirely over this switch - I guess we'll just have to wait and see what the next chips look like.varase - Wednesday, November 25, 2020 - link
Most people are looking at these first Apple Silicon Macs wrong - these aren't Apple's powerhouse machines: they're simply the annual spec bump of the lowest end Apple computers with DCI-P3 displays, Wifi 6, and the new Apple Silicon M1 SoC.They have the same limitations as the machines they replace - 16 GB RAM and two Thunderbolt ports.
These are the machines you give to a student or teacher or a lawyer or an accountant or a work-at-home information worker - folks who need a decently performing machine who don't want to lug around a huge powerhouse machine (or pay for one for that matter). They're still marketed at the same market segment, though they now have a vastly expanded compute power envelope.
The real powerhouses will probably come next year with the M1x (or whatever), rumored to have eight Firestorm and four Icestorm cores. Apple has yet to decide on an external memory interconnect and multichannel PCIe scheme, if they decide to move in that direction.
Other CPU and GPU vendors and OEM computer makers take notice - your businesses are now on limited life support. These new Apple Silicon models can compete up through the mid-high tier of computer purchases, and if as I expect Apple sells a ton of these many will be to your bread and butter customers.
In fact, I suspect that Apple - once they recover their R&D costs - will be pushing the prices of these machines lower while still maintaining their margins - while competing computer makers will still have to pay Intel, AMD, Qualcomm, and nVidea for their expensive processors, whereas Apple's cost per SoC goes down the more they manufacture. Competing computer makers may soon be squeezed by Apple Silicon price/performance on one side and high component prices on the other. Expect them to be demanding lower processor prices from the above manufacturers so they can more readily compete, and processor manufacturers may have to comply because if OEM computer manufacturers go under or stop making competing models, the processor makers will see a diminishing customer base.
I believe the biggest costs for a chip fab are startup costs - no matter what processor vendors would like you to believe. Design and fab startup are _expensive_ - but once you start getting decent yields, the additional costs are silicon wafers and QA. The more of these units Apple can move, the lower the per unit cost and the better the profits.
The real threat to OEM computer and processor makers are economic - and that fact that consumer publications like Consumer Reports will probably _gush_ over the improvements in battery life and performance.
Most consumers are not Windows or macOS or ChromeOS fanboys - the just want a computer which is affordable and has decent build quality and gets the job done. There are aspirational aspects of computer purchases, and M1 computers shoot waaayyy above their peers. This can mean a potential buyer _doesn't_ have to buy way up the line for capabilities he or she may want sometime during their ownership window, and these computers will last a long long time and will not suffer slowdowns due to software feature creep.

Remember that this is designed to be Apple’s lowest end Mac chip. Their Intel i3. Wait until the big chips come out next year.BushLin - Wednesday, November 18, 2020 - link
... Your speculation may or may not be correct but next year will see 5nm zen 4 which is actually announced rather than rumors.jospoortvliet - Wednesday, November 18, 2020 - link
Sure, and 3nm m2. Different generation with different processes etc. But today, M1 has the best single core and at lower power comes close to octacores despite only 4 fast and 4 slow cores. I wish I could buy it with Linux on it...dysonlu - Sunday, February 21, 2021 - link
"makes we wonder why Apple is so willing to fracture their already pretty small Mac OS fanbase"You have it upside down. It is exactly BECAUSE it has a small fanbase that it can afford to do this kind of migration. (The large and heterogenous "fanbase" in Windows is the big achilles' heel for Microsoft when it comes to making any significant change.) There will be very little "fracture" of Apple's fanbase, if any at all. The fans will gladly move to Mx CPUs given the advantages over Intel.

People are giving apple too much credit here, this is only impressive because of the process advantage which has nothing to do with apple.People are forgetting that Mac's have a tiny market share and that's not likely to change any time soon. You wouldn't knows it because journos tend to use Mac's therefore they think everyone does.
If anything I hope this kicks AMD into gear they are still releasing gcn designs. Let's see who's boss when they release 5nm rDNA 2

"this is only impressive because of the process advantage"False. A crap core on a high-tech process will still produce bad results; you only have to look at the last bunch of Zhaoxin CPUs based on the old Via tech.
If this were just about process node you'd expect to see lower power but with limited performance. As it is, they manage both extremely low power *and* very competitive performance. Beating Intel is no small feat, even in their current incarnation.
