Hardware / Re: Threadripper Builds
« on: 2019-11-10, 18:27:53 »Are you talking about GI precomp or overall performance while comparing to i9 ? You probably know it but animation UHD cache takes longer to calculate compared to normal "still image" cache. Maybe you was using normal uhd cache on i9 and comparing it to animation cache ?
I just tested some of my scenes and indeed, while precomputing GI, cpu utilization is around 41-46%.
EDIT : on Intel machine, 100% while precomputing GI. Weird.
Ah, yes that's exactly it. I did a side-by-side comparison purely for animation GI calcs - set to calculate and save to file, and the i9 utilizes 100% and the Threadripper is exactly the same as you got. Interestingly again, if I do set the memory frequency to 2933 in the bios, utilization increases to a little over 55%.
Once onto the actual rendering though, the Threadripper is a constant 100% and gives very impressive performance.
-- Juraj, I've never noticed GI utilization before either, however now that I am calculating GI cache exclusively for a large number of scenes, I noticed it for the first time.
