Samsung has successfully completed the validation of the LPDDR5X-8500 for Qualcomm Snapdragon mobile devices, now nothing stands in the way of new smartphones with the fastest storage. But LPDDR has recently gone much further, be it in many notebooks or in the future also on or in addition to high-end CPUs.
It is the long-awaited next step, which Samsung is now officially going. Because after the LPDDRX memory with a bit rate of 7.5 Gbit/s was presented in spring, the next stage is now following. And it doesn't come as a surprise from Samsung either, Samsung presented its first LPDDR5X RAM in November 2021, already promising a maximum of around 8.5 Gbit/s.
Here and now they are not only presented, but also already validated. Samsung still speaks of 8.5 Gbps, the official JEDEC specifications call for LPDDR5X-8533 with 8,533 MT/s, which corresponds to a real memory clock of 533 MHz and an effective memory clock of 8,533 MHz. This should ultimately also be the case with Samsung, otherwise the memory clock would be 531.25 MHz.

With the clock rate, LPDDR5X has effectively doubled LPDDR4X, which was often used in notebooks according to the LPDDR4X-4266 standard. However, the triumph of DDR5 memory does not stop at the standard, almost every mobile platform supports LPDDR and this is used more and more often.
There are also new solutions far away from mobile companions. Nvidia recently presented the advantages of LPDDR5 as memory for its Grace processor. A high bandwidth paired with a medium-sized memory expansion at relatively low costs and very low energy requirements were the decisive factors for LPDDR5X compared to classic DDR with a lot of capacity, a low price but low bandwidth or on the other hand HBM, the very high bandwidth at extremely high costs and only smaller capacity.
