Recent news reports that Lenovo has launched the ThinkPad P1 Gen 7 mobile workstation in the U.S., featuring the world’s first LPCAMM2 memory module. The key advantage of this memory over traditional LPDDR5X is its ability to be replaced and upgraded.
iFixit has obtained this model and conducted a teardown, revealing that the most significant highlight is the LPCAMM2 memory. Compared to SO-DIMM memory, LPCAMM2 memory consumes 58% less power and saves 64% of space, representing a significant change from the LPDDR/DDR memory commonly found in most laptops.
It is widely known that LPDDR memory is usually soldered directly to the motherboard and needs to be as close to the processor as possible, making upgrades virtually impossible. On the other hand, DDR memory modules using SO-DIMM, like desktop PCs, cannot match LPDDR in efficiency.
To address this, LPCAMM2 (Low Power Compression Attached Memory Module) offers a modular design that maintains LPDDR efficiency, giving users more flexibility in choosing their desired products.
As shown in the diagram, LPCAMM2 is secured to the motherboard with three cross screws instead of being soldered directly to the motherboard, striking a compromise between the two designs.
Moreover, unlike SO-DIMM-based memory modules, each LPCAMM2 memory module is dual-channel by default, meaning you only need one for optimal performance.
Currently, Micron has launched corresponding retail products, with 64GB LPDDR5X-7500 priced at $329.99 (approximately 2,379 RMB).
Besides Crucial, Samsung and ADATA have also joined the LPCAMM2 camp. This means that even if your laptop only comes with 8GB of memory, you can manually upgrade by swapping it out. You don’t necessarily have to buy Micron’s products, as other brands are available, but it’s unlikely all PC manufacturers will adopt this memory design.
