What's wrong with DIMM?
Larger footprint, taller, longer traces and signal degradation in the connectors.

There's nothing _wrong_ with it, it performs according to spec, but it has limitations: trace length, power requirements, signal limitations, heat, etc.

#14I’m glad they explained why RAM has become soldered to the board recently. It’s easy to be cynical and assume they were doing it for profit motive purposes (which might be a nice side effect), but it’s good to know that there’s also a technical reason to solder it. Even better to know that it’s been recognized and a solution is being worked on.

#15This is fantastic news. Hopefully the cost to manufacturers is only marginal and they find a suitable replacement for their current "each tier in RAM comes with a 5-20% price bump" pricing scheme. Too bad apple is almost guaranteed to not adopt the standard. I miss being able to upgrade the ram in macbooks.
Apple ships 128 bit, 256 bit, and 512 bit wide memory interfaces on laptops (up to 1024 bit wide on desktops).
Is it feasible to fit memory bandwidth like the M3 Max (512 bits wide LPDDR5-6400) with LPCAMM2 in a thin/light laptop?

#16Remember that Haswell laptops were the last to feature socketed CPUs. RAM is nice to upgrade, for sure. As well as an SSD, but CPUs are still a must. I would even suggest upgradeable GPUs but I don't think the money is there for the manufacturers. Why allow you to upgrade when you can buy a whole new laptop?
The Framework laptop 16 features replaceable GPU.

I would say it would make the most sense to have a replaceable entire ram+cpu+gpu assemble. Just have some standard form factors and connectors for external connectors.
This way, you could keep power consumption low and be able to upgrade cpu to a new generation

These are very obscure, or perhaps I mean to say niche laptop manufacturers. We need this standard for all of them, HP, Lenovo, Acer etc.

#19I remember when Dell was the first to introduce [1] these Compression Attached Memory Modules in their laptops in an attempt to move away from soldered-on RAM. Glad this is now being more widely adopted and standardized.

I'm not sure I really get much value out of a socketed CPU, particularly in a laptop, vs something like a swappable MB+CPU combo where the CPU is not socketed.
RAM/Storage are great upgrades because 5 years from now you can pop in 4x the capacity at a bargain since it's the "old slow type". CPUs don't really get the same growth in a socket's lifespan.
