General / Re: M1 Ultra with 48 or 64 GPU cores ?

Thank you very much for this article on the performance of the M1 Max (https://jenacopterlabs.de/?p=1572) that I did not know.
Since the M1 Ultra is the equivalent of 2 M1 Max processors, I think the performance will be outstanding 😊
For the price, you can't compare a big brand Machine (+OS and software suite, after sales service...) with a machine made by yourself
However, the main reason for using the Mac are my other uses and work habits 😊

Thanks a lot for your answer, is it something you could test?
Concerning the platform, I've been working on Mac for a long time and I do a lot of other things than Metashape, I already have a lot of software on it and work habits, especially video editing and the Mac Studio is quiet and very very efficient for that
Moreover, I was able to test Metashape 1.8.4 on Mac and on PC in //.
With a basic Macbook Air M1 I had better performance than a core i7 / RTX2080 gamer PC under Windows. I imagine that the Mac Studio much more powerful than the MacBook Air will get very good results if Metashape allows to use all the cores
In fact, on Mac M1/M2 the memory is shared (unified) between the CPU and the GPU, which avoids transferring data (very time consuming) from one to the other and which allows to have a lot of video memory (64 or 128 GB). In the case of Metashape I guess this is important because the processing is done alternatively by the CPU and the GPU, I would like to have an opinion of the developers on this.

General / M1 Ultra with 48 or 64 GPU cores ?

Hello,
I'm considering buying a Mac Studio M1 Ultra with 20 CPU cores and 48 or 64 GPU cores.
My question is whether all the GPU cores will be used during processing that uses the GPU.
