In April, Samsung announced the launch of the industry’s fastest LPDDR5X DRAM. Optimized for AI applications, the new chip delivers a peak speed of 10.7Gbps and offers improved power efficiency. The company has now successfully tested it with MediaTek’s next-gen Dimensity 9400 chipset. This partnership is particularly interesting because Samsung is rumored to use the upcoming Dimensity flagship on its Galaxy S25 series.
Samsung and MediaTek successfully tested the new 10.7Gbps LPDDR5X DRAM
Built on a 12nm process node, Samsung’s new LPDDR5X (Low Power Double Data Rate 5X) DRAM (Dynamic Random Access Memory) is the smallest yet fastest among all existing LPDDRs. It topped the previous speed record of 8.5Gbps (gigabits per second) the company achieved in October 2022 by over 25%. Its specialized power-saving technologies and compact size also allowed for 25% higher power efficiency.
At launch, Samsung said these improvements make the new solution ideal for on-device AI applications. Since AI has become a norm on high-end smartphones, device makers would want to use this DRAM chip in their upcoming offerings. The company has also improved memory capacity by 30%, offering the chip in up to 32GB capacities. Generative AI tasks are resource-heavy, so this is another upgrade for AI applications.
Ahead of its expected mass production in late 2024, Samsung successfully tested its fastest LPDDR5X DRAM for use on MediaTek’s Dimensity 9400. Scheduled to arrive later this year, the new Dimensity became the world’s first chipset to be validated to deliver LPDDR5X speeds of up to 10.7Gbps. The Korean firm says it used a 16GB package for verification and completed the process within just three months.
Samsung is rumored to use the Dimensity 9400 on the Galaxy S25 series
Samsung explicitly named the unannounced MediaTek processor in its press release. While it didn’t specify, the company may also be testing the new LPDDR5X DRAM chip with Qualcomm’s next-gen Snapdragon 8 Gen 4. Rumors say it is considering using both chipsets on its Galaxy S25 series. The firm might even add its Exynos 2500 to the mix for a three-pronged chip strategy, a first for the flagship lineup.
These are unconfirmed rumors, so take the information with a grain of salt. The Galaxy S25 series is still several months away, so Samsung may still have to finalize its chip suppliers. Ideally, it would want to improve its Exynos 2500 yield rate so it doesn’t have to rely on multiple outside vendors. Or at least minimize the use of outside chips. Expect more leaks and rumors about the Galaxy S25 lineup in the coming months.
