I haven't been active for a while here, and read about the M1 pro and M1 max.

Went to a thread of the M1, to see what projects it supports.

Lots of confusing data, showing the original M1 is a capable cpu, but for some reason performs more like a mid-class cpu. Some compared it to be about twice as fast as an old core i5, others said it was faster than a core in 4c 8t. While Apple tried to compare it to an 11th gen CPU, and a GTX 1050 in terms of performance....

It becomes clear that the M1 only uses the 4 efficiency cores for crunching data.
This would explain the wide variety of benchmarks out there, and the lower performance numbers we see crunching data.


The M1 Pro comes with a faster memory bus (512bit), and either the same 8 cpu cores as the M1, or 10cpu cores.
The M1 max, will come with twice the memory bandwidth of the M1 Pro (400GBps vs 200GBps on the Pro, vs 68GBps on the M1), 10 cores, and about twice the IGP cores.

See spec table below:

Apple Silicon Specifications
                         M1	        M1 Pro	      M1 Max
Process Node.      	5nm        	5nm	       5nm
Transistors	        16 billion     33.7 billion	57 billion
CPU Cores	        8	        8 or 10    	10
GPU Cores	        7 or 8      	14 or 16 	24 or 32
Memory Bandwidth	68.25 GBps	200 GBps	400 GBps
Maximum Memory.     	16GB      	32GB      	64GB


It would be interesting to see how hot the M1 gets, to get an idea of how hot the M1 Pro and/or Max would get.

If the Pro and max have more or the same amoint of efficiency cores?

The M1 Pro and Max will definitely benefit from the faster memory bus, as well as the 2 extra cores on the higher end versions!

It would also be interesting to see if there are any other projects available than WCG, Rosetta, and Einstein, that use the M1 chipset, as these projects will more than likely also be supported on the Pro or Max.

And if there are currently M1 GPU projects available (like the Collatz perhaps)?

While the Pro ($2k, and the Max ($2800) can't be bought by themselves, but only on a laptop form, which is less than optimal for crunching data, their high price tag most certainly won't rival the performance of a high end Nvidia or AMD GPU.

Alibaba recently released a 128 core Risc-V server processor, and I'm hoping that such cpus will become the new cpus of the future for crunching data, as they are more efficient than x86 cpus.

The Apple M1 lineup are 5nm cpus. Current Risc-V cpus have no mention on lithography, but it is assumed to be between 7nm and 12nm. (More than likely 7-10nm, which is less efficient than 5nm).

besides collatz being a flawed points faucet..

there are no, and likely will not be, any projects that utilize the M1 GPU. Apple removed even the soft OpenCL support that it had. now it only supports Apple's Metal. no projects use Metal, and I doubt any will in the future.

Adobe had gotten into bed with Apple pulling "metal" covers over themselves. I don't think that "open source" is even in the vocabulary of either of these companies.

Does Premiere Pro support metal?
Starting with the 14.0 release, Premiere Pro and Adobe Media Encoder default to Apple Metal graphics rendering on macOS. This applies to new and existing projects. Apple Metal provides a modern and unified render pipeline for all users on that platform and will be the focus of our development on macOS going forward.
