What CPU to get for faster light build?

I read the building light uses CPU and RAM and I currently have 32GB RAM and intel i5 4670k CPU so should I go for intel i7 CPU or get AMD Ryzen 5 1600X with 12 threads so I can build light faster ?

Hello MorningStar

Yes better CPU’s calculate lighting faster. But the calcuIation time can change with different scenes and different lighting setups and number of CPU cores and GHz too as i know. If you are working with heavy scenes (many objects, big lightmaps, incredible heavy light setups, etc.) and you want fast result no matter what, i think you need to upgrade your CPU. I have i7 4930K (i know its old) but it does really good job with my cursed heavy scene. Hope this helps.

Thank you.
