You get fast memory as a result. If you don't care about the fast memory, there's no good reason to buy this, with their motherboard. There's a use case this serves which can't be served by traditional slotted memory and the alternative is to buy 4-5 NVIDIA 3090/4090/5090. If you want that use case, then this is a pretty good deal.
And your phone isn't repairable because it needs to be water proof. Your earbuds because of power efficiency. Etc.
Also, I suggest watching this https://www.youtube.com/watch?v=K3zB9EFntmA.
But, to be clear: I am actually not as opposed to the idea of soldered ram when you have "an excuse". Same with phones. But framework is a brand that tries to build itself on minimizing e-waste and maximizing repairability and... hey, at least we can still swap out the side panel on their prebuilt!
As far as I read LPCAMM in its current state does not work for this. The electrical noise is too high. These things aren't the same. A repairable waterproof phone can be made without glue by making it a bit thicker. In the case of RAM today, we're hitting fundamental physics limitations with speed of electricity and noise. At this point the physical interconnect itself becomes a problem. Gold contact points become antennas that induce noise into adjacent parts of the system. I'm not trying to excuse Framework here. I'm saying that the difficulty here borders on the impossible. If this RAM was soldered and it had bandwidth no different than SODIMM or LPCAMM modules then I'd say Framework fucked up making it soldered, majorly. As I said, there's no point buying this if you don't care about the fast RAM and use cases that need it like LLMs. Regular ITX board with regular AM5 is the way to go.
E: To be clear, if this bandwidth could be achieved with LPCAMM, then Framework fucked up.
