Jaffa Posted May 2, 2020 Share Posted May 2, 2020 At present I am looking to upgrade my desktop so that it can handle my high end needs using Affinity Photo. Can Affinity Photo use a CPU with 8 cores and 8 threads, or is that more than necessary please?

firstdefence Posted May 2, 2020 Share Posted May 2, 2020 I don’t think there is a limit on cores and threads, from the help appendix it just says from Core 2 Duo onwards, I think if there was an upper limit they would have specified this. https://affinity.help/photo/English.lproj/pages/Appendix/system_requirements.html Quote iMac 27" 2019 Somona 14.3.1, iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

IanSG Posted May 2, 2020 Share Posted May 2, 2020 I was looking at this yesterday because of your other thread. I found a post from one of the Serif staff saying that Affinity software tries to use as many threads as possible, but I didn't see anything suggesting a limit. Your proposed new processor doesn't seem to support hyperthreading - I was trying to work out the implications of that before replying.

This post suggests Affinity can use at least 32 "cores" in some operations Quote To save time I am currently using an automated AI to reply to some posts on this forum.

About hyperthreading, in my research I came across this comment "Yes, Photoshop uses hyperthreading when it would be faster. But in many cases we can only use physical cores and not logical (hyperthreaded) cores because hyperthreading would make the process slower." Okay, we are talking about Affinity Photo, but I guess that whilst the comment is about Photoshop, a similar thing would apply to Affinity?

Old Bruce Posted May 2, 2020 Share Posted May 2, 2020 All I can say for certain about HHGTTG and 42 is that one of the characters thought it may be the number Bob Dylan was looking for in Blowing in the Wind.

My assumption (nothing more) would be that since Affinity's much more recent, the developers have had more opportunity to take advantage of HT. How that translates into real world performance I don't know. Quote AP, AD & APub user, running Win10 Link to comment Share on other sites More sharing options...

firstdefence Posted May 4, 2020 Share Posted May 4, 2020 You could always disable hyper-threading and see what the performance differences are.

Eftaliotis Posted September 24, 2021 Share Posted September 24, 2021 I have Affinity Photo running on two machines: A desktop with a 7th gen Core i7 and RTX 2060 (4 cores, 8 threads) and a laptop with a Ryzen 9 (8 cores, 16 threads) and RTX 3060. Comparing the Affinity benchmarks from these two systems is interesting: The difference between single-core and multi-core vector performance on both machines is approximately 4X. That would seem to indicate that only a maximum of 4 cores/threads are being used, at least for that. Otherwise I would expect a significantly larger difference between single and multi core performance on the 8-core machine -- most likely not 8X, but it should be at least 6X, not just 4X.
