My goal: to fully understand the processing power/capabilities of MCU1 vs MCU2. What is it (Specifically) for example, that appears to make the combination of FSD and MCU2 much, much less troublesome than the combination of FSD and MCU1? What are ALL of the factors that make the difference? JUST a different processor? Or are there significantly more differences/improvements?

1) More Power means faster responses and less frozen screen:

MCU1=nVidia quad-core processor Tegra 3.

MCU2=Intel multi-core Atom E8000 series CPU (x86_64) processor.

2) More Memory: 4 times the eMMC 8GB increased to 32GB.
