I’m curious if any AMD X3D chip owners (5800X3D, 7950X3D, 7900X3D) know if Blender benefits from 3D V-Cache in certain operations excluding rendering, such as modeling or sculpting. What about BVH building? Or Geometry nodes?
Don’t have a X3D chip, but I suspect it really wouldn’t help all that much and may well work against performance.
My main thinking is two fold, first, even modelling, etc would still likely involve more constant changing data then would fit in the cache.
Then where it hurts is that X3D chips usually have lower power and boost clock speeds compared to non-X3D chips. I don’t think I’ve seen any reviews or tests where the X3D chips are better at anything other then gaming.
Just an update, from someone looking to upgrade from tired R5 2600x.
When looking at non gaming benchmarks all over the internet, 7950x3D seems to be actually 1-3% faster in many apps than 7950x. The pricing may be different from country to country, but in Czechia for example, the 7950x3D is actually slightly cheaper right now than 7950x.
So, from my point of view, if you’re going AM5 and want the best, go with 7950x3D. That might change with new Zen generation, but that’s currently still a long time away.
