That's a big bet on the RAM modules. If LPCAMM2 doesn't take off, one of the most likely upgrade paths is going to be a lot more expensive.
It’s very important, though.
Laptop DDR5 is at the ragged the edge of what SODIMMs can electrically support. Voltage is pushed very high, and latency pushed way out, on top of all sorts of signaling trickery, yet it’s still slow enough to bandwidth starve modern CPUs and their IGPs.
In other words, I understand wanting good old SODIMM sticks, but I don’t think most realize just how limiting they are. They’re already sucking power and capping performance.
…And, TBH, I suspect desktop DIMMs are approaching that point, too. LPCAMM on some near-future motherboard would be a huge selling point for me.
Lenovo seems onboard so it's not that far fetch of a bet.
