Intel’s Lunar Lake Processors to Use Samsung LPDDR5X On-Die Memory with 8533MHz Speeds


Intel’s Lunar Lake is an upcoming processor architecture that the company plans to release in the future. A recent report from Digitimes has provided intriguing insights into this upcoming lineup.

According to the report, Intel intends to incorporate on-package LPDDR5X RAM for its Lunar Lake CPUs, with Samsung Electronics selected as the supplier. What precisely does “on-package” or “on-die” memory mean? In many laptops, the RAM is soldered directly onto the motherboard, rather than being modular and upgradeable.

By utilizing on-package LPDDR5X RAM, Intel aims to minimize latency in communication between the processor and system memory by placing the LPDDR5X RAM modules adjacent to the CPU. This approach is expected to enhance performance and efficiency in Lunar Lake CPUs.

In addition to the Digitimes report, leaked Intel documents shared by user @yuuki_ans on the AnandTech Forums have also indicated a similar design for Intel Lunar Lake processors. The leaked documents suggest that Lunar Lake CPUs will have integrated LPDDR5X RAM, with “memory capacity being part of the SKU“, or stock-keeping unit.

This integration means that the LPDDR5X RAM will be directly incorporated into the processor die. Additionally, the leaked documents mention impressive RAM speeds of up to 8533MHz for Lunar Lake processors. Furthermore, the architectural design of Lunar Lake CPUs appears to be distinct from previous architectures such as Meteor Lake and Alder Lake.

The proposed integration of LPDDR5X RAM next to the processor, coupled with the impressive speeds offered by Samsung’s LPDDR5X memory, sets Intel Lunar Lake apart from previous architectures. While Samsung is mentioned as a supplier for this integrated design, it’s uncertain whether Intel will exclusively partner with them for future chips.

Considering other RAM manufacturers like Micron and Hynix, it remains unclear if they will also play a role in supplying components for Lunar Lake CPUs. If Samsung becomes the sole supplier, it would mark a significant achievement for the company. However, this information is not confirmed by Intel, and the DigiTimes report only mentions Samsung without referencing competitors.

The concept of Lunar Lake featuring non-upgradeable LPDDR5X RAM integrated next to the CPU raises questions about user flexibility and potential limitations. Share your thoughts on Intel Lunar Lake and the implications of this design choice in the comments below.
