Samsung has successfully validated its new LPDDR5X-10700 memory with
MediaTek's upcoming Dimensity platform. At present, 10.7 GT/s is the highest
performing speed grade of LPDDR5X DRAM slated to be released this year, so
the upcoming Dimensity 9400 system-on-chip will get the highest memory
bandwidth available for a mobile application processor.

The verification process involved Samsung's 16 GB LPDDR5X package and
MediaTek's soon-to-be-announced Dimensity 9400 SoC for high-end 5G
smartphones. Usage of LPDDR5X-10700 provides a memory bandwidth of 85.6
GB/second over a 64-bit interface, which will be available for bandwidth-
hungry applications like graphics and generative AI.

"Working together with Samsung Electronics has made it possible for
MediaTek's next-generation Dimensity chipset to become the world's first to
be validated at LPDDR5X operating speeds up to 10.7Gbps, enabling upcoming
devices to deliver AI functionality and mobile performance at a level we have
never seen before," said JC Hsu, Corporate Senior Vice President at MediaTek.
"This updated architecture will make it easier for developers and users to
leverage more AI capabilities and take advantage of more features with less
impact on battery life."

Samsung's LPDDR5X 10.7 GT/s memory in made on the company's 12nm-class DRAM
process technology and is said to provide a more than 25% improvement in
power efficiency over previous-generation LPDDR5X, in addition to extra
performance. This will positively affect improved user experience, including
enhanced on-device AI capabilities, such as faster voice-to-text conversion,
and better quality graphics.

Overall, the two companies completed this process in just three months.
Though it remains to be seen when smartphones based on the Dimensity 9400
application processor and LPDDR5X memory are set to be available on the
market, as MediaTek has not yet even formally announced the SoC itself.

"Through our strategic cooperation with MediaTek, Samsung has verified the
industry's fastest LPDDR5X DRAM that is poised to lead the AI smartphone
market," said YongCheol Bae, Executive Vice President of Memory Product
Planning at Samsung Electronics. "Samsung will continue to innovate through
active collaboration with customers and provide optimum solutions for the on-
device AI era."
