Samsung's new low power, high performance memory range could be a serious boon for compact gaming laptops

pcgamer.com:

Samsung's new laptop memory range promises upgradeable memory without the performance glass ceiling of SO-DIMMs. Its newly announced range of Low Power Compression Attached Memory Modules (LPCAMMs) will dramatically shrink the amount of space normally given over to traditional laptop memory modules, but don't expect that to mean a reduction in the number of soldered-on solutions.

Right now, when it comes to DDR5 in laptops you either have replaceable SO-DIMMs or, where size is a concern, you get the memory chips themselves soldered onto the mainboard itself. That's the better solution for compact laptops, as it takes up less space and can be faster, too. But it means manufacturers have fewer options for different memory configurations—hence why something like the Asus ROG Zephyrus G14 has a 32GB limit as it has 16GB soldered onto the board, with an optional 16GB available via SO-DIMM.

But if you're going for that half-and-half method, you are restricted to the speeds of the SO-DIMM socket and, at the moment at least, that means you are restricted to 6400MT/s modules. And if you want to go for the low power LPDDR5, which offer higher speeds and lower power, they have to be soldered onto the board. 

Samsung's new LPCAMMs, however, can bring you the best parts of SO-DIMMs and LPDDR5 into one handy package. You get replaceable memory modules, with higher speeds, and they come in a super small form factor, up to 60% smaller than a traditional SO-DIMM setup.

The Korean company has shown off renders of an LPCAMM module running with 4 LPDDR5X packages mounted on it, with a vastly smaller footprint than a dual SO-DIMM solution. 

Essentially the LPCAMM is attached to the motherboard, with socketed connections directly underneath
