Samsung Electronics, the world leader in advanced memory technology, today announced it has successfully completed verification of the industry’s fastest 10.7 gigabit-per-second (Gbps) Low Power Double Data Rate 5X (LPDDR5X) DRAM for use on MediaTek’s next-generation Dimensity platform.

The 10.7Gbps operation speed verification was carried out using Samsung’s LPDDR5X 16-gigabyte (GB) package on MediaTek’s upcoming flagship Dimensity 9400 System on Chip (SoC), scheduled to be released in the second half of this year. The two companies have closely collaborated to complete the verification within just three months.

Samsung’s 10.7Gbps LPDDR5X delivers more than 25% improved power consumption and performance compared to the previous generation. This allows longer battery life for mobile devices and enhanced on-device AI performance, boosting the speed of AI features, such as voice-text generation, without requiring server or cloud access.

“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.”

“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’ve 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.”

Amid the expansion of the on-device AI market, especially for AI smartphones, energy-efficient, high-performance LPDDR DRAM solutions are becoming increasingly important. Through the validation with MediaTek, Samsung is solidifying its technological leadership in the low-power, high-performance DRAM market and is expected to expand the application beyond mobile to servers, PCs and automotive devices.

The demands on uplink performance are increasing with the rise of live streaming, multi-player gaming and video conferences. Upload speeds determine how fast your device can send data to gaming servers or transmit high-resolution videos to the cloud. As more consumers seek to document and share their experiences with the world in real-time, enhanced uplink experiences provide an opportunity to use the network to improve how they map out their route home, check player stats online and upload videos and selfies to share with friends and followers.

While current smartphones and customer premise equipment (CPEs) can only support 2Tx antennas, this industry-first demonstration validated the enhanced mobile capability of 3Tx antenna support. This approach not only improves upload speeds but also enhances spectrum and data transmission efficiency, as well as overall network performance.

The test was conducted in Samsung’s lab, based in Suwon, Korea. Samsung provided its industry-leading 5G network solutions, including its C-Band Massive MIMO radios, virtualized Distributed Unit (vDU) and core. The MediaTek test device featuring its new M80-based CPE chipset began with one uplink channel apiece at 1,900MHz and 3.7GHz, but added an extra uplink flow using MIMO on 3.7GHz. Both companies achieved a peak throughput rate of 363Mbps, an uplink speed that is near theoretical peak using 3Tx antennas.

“We are excited to have successfully achieved this industry breakthrough with MediaTek, bringing greater efficiency and performance to consumer devices,” said Dongwoo Lee, Head of Technology Solution Group, Networks Business at Samsung Electronics. “Faster uplink speeds bring new possibilities and have the potential to transform user experiences. This milestone further demonstrates our commitment to improving our customers’ networks using the most advanced technology available.”

“Enhancing uplink performance using groundbreaking tri-antenna and 5G UL infrastructure technologies will ensure next-generation 5G experiences continue to impress users globally,” said HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek. “Our collaboration with Samsung has proved our combined technical capabilities to overcome previous limits, enhancing network performance and efficiency, opening up new possibilities for service providers and consumers to enjoy faster and more reliable 5G data connectivity.”

“With demands on mobile networks rising, enhancing upload performance is essential to improving consumer and enterprise connectivity, as well as application experiences,” said Will Townsend, VP & Principal Analyst at Moor Insights & Strategy. “Samsung and MediaTek have achieved an important 5G Standalone milestone in a demonstration which underscores a tangible network benefit and does so in a way that can help operators maximize efficiency.”

Samsung has pioneered the successful delivery of 5G end-to-end solutions, including chipsets, radios and core. Through ongoing research and development, Samsung drives the industry to advance 5G networks with its market-leading product portfolio, from virtualized RAN and Core to private network solutions and AI-powered automation tools. The company currently provides network solutions to mobile operators that deliver connectivity to hundreds of millions of users worldwide.
