Well, I'm totally thrilled with a new 14/16 inch MBP and the performance blew my mind. I'm already happy with M1 without any issues in terms of performance which makes me feel not to buy M1 Pro/Max. But I really need to buy a higher end Mac because of Photoshop project. I know that M1 is totally enough or more than enough for Photoshop cause it works great and it really does. But the only concern is about a large project. This is why I waited for a higher end MBP or iMac.
Each project file size is between 10~30GB. Yes, it is huge. I tried it with Mac Pro 2013 and iMac Pro with 64GB of RAM but they were extremly slow to handle a such file. The memory was maxed out. Apple Silicon Mac with unified memory should be much faster but I'm still worrying about the RAM usage. Someone suggested to reduce the amount of RAM that Photshop can use but I dont think it will increase the performance. M1 with 16GB struggles so much with a huge file. The canvas size is 66X44 at 300 PPI. Zoom in and out is totally laggy and even iMac Pro suffered that.
I'm waiting for Apple Silicon desktop with 64GB of RAM but do you think the struggle is more about the RAM size, CPU performance, or GPU performance?
