Note that M1 Pro would have performed the same but they didn't include it in the chart.

For Conclusion & Summary


I feel sad that Apple will never make a desktop SoC that has Intel Core i9 or AMD Threadripper TDP.

The best we can hope for is a multi SoC/die configuration of the M1 Max on the iMac Pro or Mac Pro.

For context for non-PCMasterRace types
  • M1 Pro & M1 Pro Max are used in laptops with 67W, 96W and 140W chargers
  • Intel Core i9-11900K is a year 2021 125W desktop processor
  • Intel Core i9-10900K is a year 2020 125W desktop processor
  • AMD Ryzen 7 5800X a year 2020 105W desktop processor
  • AMD Ryzen 9 5900X is a year 2020 105W desktop processor
  • AMD Ryzen 9 5950X is a year 2020 105W desktop processor
I find it really disheartening that Apple's trend towards systems that uses relatively lower power consumption will not allow for a MBP 16" with a 240W USB PD charger.

So the odds of a iMac 27" or larger screen replacement with 500W PSU is very unlikely unless these are multi SoC/die M1 Max configurations to allow for more than 64GB memory like say 128GB, 256GB, 512GB, 1TB or 2TB using multiple M1 Max SoC/die

What?

They will. Starting with the Mac Pro SoC 40/128 SoC. Apple will most certainly chop that in half and offer a 20/64 SoC.

And they might put that 20/64 SoC into the iMac Pro.
he is saying the same thing...those 20/64 SoC is an 2x M1 max

thats the rumor but for the mac pro maybe apple will allow a 1 M1 max not to be limited at 30W for the cpu and 60 for the gpu 3.2ghz cpu freq...so we will never know until 1 year from now

I say this as the iMac 24" has the same exact M1 SoC as those found on the Mac mini & laptops. The iMac sells more units than iMac Pro and Mac Pro combined because of the price difference.

Economies of scale of a desktop SoC designed specific for the Mac Pro & iMac Pro that ships for less than a million out of more than 22.5 million all Macs per year would probably not work.

Today's M1 Max with an undicslused feature for multi SoC configuration makes more sense.

2019 Mac Pro with a 1,400W PSU allows for up to 1.5TB memory. That's equivalent to nearly 24 M1 Max 64GB SoC.

For those of us who arent that articulate or in the know what does Andrei mean?

Another way to put it is that the GPU ramps up to the max clock speed over time, as a power saving measure.

One issue with Intel’s CPU clock speed ramp ups is that you get a sort of “overshoot” by blasting the max turbo speeds for tasks that really don’t need it. The end result is using more energy for a “task” than it would have if it was more conservative on the turbo boost. I suspect this is the sort of thing Apple is trying to avoid by more gradually ramping up the clocks.

I suspect “High Power Mode” would make the ramp up to max clocks more aggressive as well, but I could be wrong.

Wow... that thread title is... really misleading at best...

Yes, the M1 Max (& likely the M1 Pro) achieve higher MT SPEC floating point performance scores than a 5950x and that is incredibly impressive, but that is primarily due to having roughly 10x(!) the available memory bandwidth which allows it to destroy the competition in memory bound portions of the test. It's certainly cool to see, and will likely put the M1 Pro/Max in a class of their own for certain specific tasks, but that kind of performance scaling is not where the majority of apps in the real world are going to land.

If you look at the integer performance its just above the Ryzen 5800X (an incredibly impressive result) so for mixed workloads I'd imagine the most comparable (desktop!) CPU parts would be the Ryzen 5800X (8C/16T), the i9 10900K (10C/20T) and the Ryzen 5900X 12C/24T, depending on the workload (for context, these are basically the fastest 8, 10, and 12 core CPU's money can buy.)
I think we can all agree this is incredibly impressive for a chip that maxes out at around 35W and can fit in a 14" laptop without needing to resort to hyperbole and claiming its "Max multithread performance is like Ryzen 5950x."

Of course, again, with 10x the memory bandwidth and the equivalent of a built in Afterburner Card on the SOC it's going run circles around even the fastest Mac/PC workstations for some tasks.

This generation of MacBook Pro's is certainly going to be a wild ride and I can't wait for more people to get their hands on them and more data to be published (not to mention have one to test myself!)

Not only that. M1 simply has more flexible floating point execution. It offers four independent FP ALUs (128bit each) while Zen3 has more limited execution (if I understand it correctly it can execute four FP ops per clock but only under specific circumstances). Since not all code can be vectorized, real world FP workloads do end up doing quite a lot scalar operations and M1 will retire them quicker, especially combined with its huge caches.

This is already something I have experienced with the base M1. In numerically heavy code (stan, basic regression), it was slightly outperforming my 8-core i9. Cache + more FP units do wonders on scientific code.

Sure. My point wasn't that the M1 Pro/Max (and even M1) aren't floating point monsters (they are, and they're awesome) but that outside of a limited subset of applications, expecting 5950X level MT performance out of an M1 Pro/Max is unrealistic (something that, to be fair, the article itself never claims.)

This massive fp performance combined with fast access to GPU resources without worrying about copying data back and forth between CPU and GPU could unlock a lot of new algorithms for scientific computing. But yeah, not for everyone/every workload.

M1 Max TDP is solidly in the desktop territory. Anandtech:

Finally, stressing out both CPU and GPU at the same time, the SoC goes up to 92W package power and 120W wall active power. That’s quite high, and we haven’t tested how long the machine is able to sustain such loads (it’s highly environment dependent), but it very much appears that the chip and platform don’t have any practical power limit, and just uses whatever it needs as long as temperatures are in check.

The laptop they tested it against hit a 220W package power on the same workload.

The entire SOC? Sure, but the only thing comparable today would be the PS5/Xbox Series X/S as the last PC part with a GPU anywhere near this fast would be the 100W TDP i7-8xxxG with Radeon™ RX Vega graphics. The M1 Pro/Max CPU appears to draw ~43W max for the CPU by itself putting it solidly in mobile territory.
