Yes, that’s true, but it’s still an indicator of an uninformed reporter.
Apple Silicon chips pass data from one dedicated cores directly to another without the need of passing through memory, hence the smaller processor cache. There are between 18 and 58 cores in the M3 (model dependent). The architecture works very differently than the conventional CPU/GPU/RAM model.
I can run FCP and Logic Pro and have memory to spare with 16GB of UM. The only thing that pushes me into swap is Chrome. lol
