> So given that most laptops sold by companies like Dell and Lenovo use soldered ram anyway, and that Intel and AMD both support LPDDR, then why are PC laptops with faster RAM so rare? I have no idea, maybe it costs a bit more and the manufacturers don't think they can market it as a benefit?

For consumers, the primary application that benefits from higher RAM bandwidth is real-time graphics rendering, and non-Apple PCs optimize for this by using discrete GPUs with their own onboard high-bandwidth memory.

I wouldn't take the statement at face value. Most laptops base on 11th-gen Core and later Intel CPUs use LPDDR4x, just like the M1. It's not rare at all. It is the reference design from Intel.
