This is LPDDR5X-6400
Non-binary RAM modules will appear in laptops in the near future. At a minimum, preliminary data about Honor MagicBook Pro indicates that this new product has exactly these modules. The laptop's RAM capacity is 24 GB. Of course, technically it could be a 16 GB module and another 8 GB module, but no one does that, and in the current case it is directly stated that these are non-binary 12 GB modules.
More specifically, this is LPDDR5X-6400 memory. The heart of the new PC is the Core Ultra 5 125H, but modifications with other CPUs in this line will probably be available.
Non-binary modules allow manufacturers to offer a wider range, since in addition to options with 16, 32 and 64 GB, laptops with 24, 48 and 96 GB of RAM will now be available.
