what does NDI mean?On an M1 with 8GB of unified memory, Resolume would let me have (6) 1280x720p24 slices out NDI. On an M1 with 16GB of unified memory, Resolume would let me have (9) 1280x720p24 slices out NDI. But, it was only using 12-13GB of unified memory. It wasn’t using all 16GB. But, the CPU and GPU were maxed out at 95%+.
So, yes, there is a cause and effect relationship between unified memory and some types of performance in Resolume. But, until you test two different machines and compare them side-by-side, you can’t really know what the exact differences are. Sorry. But, unified memory is a new idea and no one really knows how to think about it or predict with any level of certainty what amount you need or what the impact will be, because regular people like us don’t know where the bottlenecks are. Ya know?
Is it CPU? Is it GPU? Is it memory bandwidth? Is it OpenGL’s single-thread rendering? Who knows? I don’t.
Yes, this is difficult... we can just try out and get experienced. I think I will not need more than 32 GB unified memory, hope this will be true for the next years!
