About a month ago, I started to put together a new system (see;https://www.dpreview.com/forums/post/66611828 for the result and parts list). My main goal was to speed up Photoshop, DxO DeepPrime, and Topaz AI sharpening with my R5's 45MP files.
My favored "flow is to run cRAW files through DxO PL4 with DeepPrime and export 16-bit tiff to Photoshop. Many (most by count) of my shots are hand-held pictures of propeller planes taken handheld with panning at 1/60th to 1/125th of a second at 200mm to 500mm on an RF100-500. There is a lot of culling of electronic shutter bursts, but then I use Topaz AI sharpener to improve the best shots.
On my old system, it typically took over a minute to go from DxO PL6 to Photoshop and then 1 to 2 minutes for Topaz AI sharpening to do its thing (highly variable based on image content).
My old PC was built in 2015. Key components:
Looking at the performance monitors, it looks like both DxO PL6 and Topaz AI Sharpen primarily highly utilize the GPU, BUT only in the new system.
On the old systems, DxO does most of its work on the CPU (~60% loaded) and barely touches the GPU (only a few percent). Topaz on the old system loads the much less capable GPU by only about 30% on the old system. On the new system, DxO and Topaz are at about 90% GPU utilization while running, while the CPU is at only at 2-3%.
On the surface, it looks like DxO took almost no advantage of the old Nvidia P4000 GPU whereas the Topaz utilized it significantly. With the new 3080TI, they both took full advantage of the graphics card.
In "real used" with more complicated images with many more layers, I would expect the new system with 64GB and much faster memory and M.2 SSDs will help. I was always bumping up against filling up the 32GB on the old system.
It would be interesting to see how much just swapping the graphics card would have done in my old system, at least on DxO and Topaz. Unfortunately, I don't think the power supply of my old system is up to driving the 3080TI, and I don't want to take the time and risk swapping it over.
Programs seem to open up about 2 times faster with the new system (8 seconds on the new vs. 16 seconds for Photoshop on the old system).
