#22This 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?

Heck, make it only run full tilt when on an active cooling dock. Let it run half power when unassisted.

#26Remember 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?
Because you can't swap the motherboard, your options for CPUs are going to be quite limited. Generally, only higher-tier CPUs of that same generation - which draw more power and require more cooling.
Generally a laptop is built designed to provide a specific budget of power to the CPU and has a limited amount of cooling.
Even if you could swap out the CPU, it wouldn't work properly if the laptop couldn't provide the necessary power or cooling.

And soldering stuff to the board is the default way to make something when upgradeability isn't a feature.

#28I do hope that a more widespread usage of compressed attachment gives us some development in that area where projects that were promising modular devices failed (remember those 'modular' phone concepts? available physical interconnects were one of the failures...). Sockets for BGAs have existed for a while, but were not really end-user friendly (not that LGA or PGA are that amazing), so maybe my hope is misplaced and many-contact connections will always be worse than direct attachment (be it PCB or SiP/SoC/CPU shared substrate).

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.
The technical differences between sockets aren't usually huge. Upgrade the memory standard here, add or remove PCIe lanes there. Using new cores with an older memory controller may or may not be doable, but it's quite simple to not connect all the PCIe lanes the die supports.

On a laptop it's not very practical. Because you can't swap the motherboard, your options for CPUs are going to be quite limited. Generally, only higher-tier CPUs of that same generation - which draw more power and require more cooling.

And the good thing about mobile CPUs is that they have almost the same TDP across the various dual-quad versions(or whatever is the norm today).
