AMD CPUs and Nvidia with CUDA are said to perform much better with Adobe CC suite than the Intel CPUs and AMD GPUs that Macs are stuck with.
Isn't that only true for video editing and 3D? Are there any published benchmarks that show CUDA making any difference at all for Photoshop or any other still image editor application?
Also, Affinity Photo is GPU optimized for Apple Metal, not CUDA.
I haven't used Capture One but found an article from last year about it and GPU acceleration (on PCs). CUDA is not mentioned. OpenCL is. There is a chart of GPUs, the AMD Vegas seem to be up near the top. Also it says "On one hand, it’s nice to see that you don’t need to go with a high-end graphics card to get good performance out of Capture One. On the other hand, it’s unfortunate that those with higher-end cards already won’t see much of an advantage in this particular application."

Also found a Capture One help page about GPU and Mac:
https://support.captureone.com/hc/e...OpenCL-do-and-how-do-I-use-it-in-Capture-One-
It does say a higher number of CUDA cores helps, in one paragraph. But the rest of the page is all about OpenCL as the primary GPU accelerant for Capture One.
On the Mac, Apple is deprecating OpenCL because they want developers to use Apple Metal.
As for a DAM, it is competition that we all badly need and is not there. Affinity talked about it like 5 years ago, users regularly pester them about it on their forums.
But in 2017 Affinity put out a tweet:
We aren't working on a DAM. We've thought about working on one, but we are currently focused on other projects.
Their next big release was a layout program (Affinity Publisher) instead.
