While this could be true, I have following indicators to it not being true:
- bw & color have the exact same cpu core voltages for the frequencies they share - so the MT8113L is likely not another "lower power" process. So it is unlikely, that the cores are not similarly capable as the other one. I dod not see any stability problems in my tests so far, but I didn't try long.
- If you search the internet for MT8113L it likely doesn't exist
- Even if it exists, I can't believe it makes sense to save a few cents per piece and need a different stack of PCBs for that.
the ntx firmware file is different for bw & color - also there might be a hwconfig bit doing some initialisation that doesn't allow the second core to come up on my device.
Or you are just right and it doesn't exist
