Yep! Though one could argue the Amiga wasn't true unified memory due to the chip RAM limitations. Depending on the Agnus revision, you'd be limited to 512, 1 meg, or 2 meg max of RAM addressable by the custom chips ("chip RAM".)

fun fact: M-series that are configured to use more than 75% of shared memory for GPU can make the system go boom...something to do with assumptions macOS makes that can be fixed by someone with a "private key" to access kernel mode (maybe not a hardware limit).
I messed around with that setting on one of my Macs. I wanted to load a large LLM model and it needed more than 75% of shared memory.
