2GB makes all the difference in running on device models depending on how large the models are. I'm not an Apple fanatic if my posts in this very thread says anything but I do run various AI models locally on device just an enthusiast not in a professional capacity and RAM is 1 big factor in determining how well a model operates.Yet the M1 with 11 TOPS and M2 with the same 15.8 TOPS as the A15 is just fine somehow? The 2GB of less RAM would make very little difference as the neural engine is the chip doing the vast majority of the processing.
