Have been deciding for ages between the 24gb 12/16, 24gb 14/20 and 36gb 14/32.

I use Lightroom for hobby purposes only, so typically 30-100 photos per session. I use alot of adjustments including AI and AI noise. So I am just looking to make these sessions more speedy. Otherwise its a few games and standard office and browsing and very occasionally video editing.

The hole that Apple sucks you into is to offer a tantalisingly cool machine at the bottom end which just misses the mark in terms of what you really want. The amount of time I tried to convince myself that 512gb is ok, but for editing on the go whilst travelling, and storing backups to pictures on cfexpress cards and travelling netflix and prime videos, it falls short. And I really dont want to rely constantly on external drives when travelling. And then there is performance. What is the real difference between 10, 16, 20 and 32 GPUs ?

I watched some very good youtube videos comparing performance. It seems that with lightroom, 10 gpus is noticeably slower then 16 and 20 which are very similar. Interestingly 32 doesn't make much difference as lightroom is more memory constrained. 24gb seems to be the lower memory that maximises speed, with a graduation up to 48gb. So 48gb and 20 gpus is actually better then having 36gb and 32 gpus.

At the end - cost vs performance, I chose the 24gb 14/20. I really could have got away with the 12/16, but Apple sucked me into the extra £370 for more cpus and storage, which I convinced myself was cheap considering I was already near £2k.

looking forward to its delivery and cutting down my old i5-13 desktop development time in a much smaller and portable package!

I do 1,500 to 2,000 images per session. I photograph sporting events. I need to narrow those images down to about 100. I can process those images in about an hour, including color correction, exposure correction, and cropping of the final 100 images.

I was able to do this on my prior MacBook M2 Air. My current M4 Pro is not significantly faster in doing that process. The real advantage is the ability to use the SDXC card slot on the Pro, the same memory cards my camera uses. Importing is faster, rendering thumbnails is faster. However, that time is when I went to the bathroom so the speed increase was not really applicable.
