LPCAMM2, a possible RAM revolution for laptops

Over the weekend I watched a video on the iFixit channel about the LPCAMM2 (LPDDR5X) RAM memory module integrated into the new Lenovo ThinkPad P1 (Gen 7) laptop. In short, LPCAMM2 is a new modular laptop memory standard that is easier to upgrade and repair in portable devices.

Current RAM and what LPCAMM2 adds

LPCAMM2, developed by Micron and Lenovo, is a memory platform that uses LPDDR (Low-Power Double Data Rate) chips. This new standard is designed to be modular, repairable and upgradeable, giving users the ability to add or replace RAM as their needs evolve.

At the moment, for reasons of space and performance, in laptops the RAM memory is often glued to the motherboard and you can no longer add more memory. In the case of Apple’s M-series SoCs, the RAM is integrated into the chip and is accessible to both the CPU and the GPU. This provides a faster data transfer, but decreases the possibility of upgrading.

This means that when you buy a MacBook Air or any other Apple laptop with an M processor, you have to choose how much RAM you want up front, because you won’t be able to upgrade it later. There is also a dispute on this topic, whether 8GB of RAM is enough for an Apple computer in 2024.

A single LPCAMM2 module can handle data on two separate channels simultaneously, similar to how two separate memory modules would operate in a traditional system. This feature allows the LPCAMM2 module to provide the same performance as two conventional SO-DIMM modules, but occupying less space and generating less heat.

Micron Technology says the LPCAMM2 is available in memory modules from 16GB to 64GB. And that the new LPDDR5X technology enables speeds of up to 9600Mbps, compared to 5600Mbps, the maximum speed of current DDR5 SODIMM modules. It is designed to consume up to 61% less power and deliver up to 71% better performance for critical tasks such as web browsing and video conferencing compared to traditional SODIMM solutions.

We don’t yet have enough data to approve or dispute what is being said about the LPCAMM2, as there is only one laptop released with this new technology that we haven’t gotten our hands on. But any technological advance, while bringing improvements in performance and efficiency, is developed and marketed not just for the technical benefits it brings to consumers, but also for its potential to generate substantial profits for companies. Until the benefits are also evident for businesses, the widespread adoption of LPCAMM2 by other laptop manufacturers remains uncertain.
