Nothing factual about calling someone a liar when you have no idea, and yes attitude. Enough that I have no desire talking about this with you despite your knowledge on the topic.

If you cannot acknowledge that the Switch's memory sub-system runs at different speeds, those being 1333mhz or 1600mhz, I am not sure what to tell you.

But here is the evidence anyway:
https://www.eurogamer.net/digitalfoundry-2016-nintendo-switch-spec-analysis

Switch Docked: 1600Mhz.
Switch mobile: 1331Mhz.
Switch mobile with dev override: 1600mhz.

Latencies are adjusted to match the JEDEC specs.

Really nothing else to say on this except your assertions prior is false.

I told you I was okay with that and can change my point of view on this it's not the end of the world. The part I was challenging is that you said any memory chip can be interchanged on a piece of hardware, but you can't really on a closed device. Meaning that the card's bandwidth itself is set upon manufacturing. For example, the switch is manufactured as LPDDR4 1632MHz, so it is designed to have a bandwidth of 1632 x 2 (dual) x 8bytes (bus width) / 1024 (Mega to Giga) = 25.5 GB/s. Don't you agree on this?

Edit: Another point I want to mention is that the memory bus width is fixed in the motherboard and can't be changed after manufacturing. For example, on the Nintendo switch, it is 64bits. Some part of the badwidth calculation are fixed.
