LPDDR5 vs LPDDR5X: What’s the difference?

LPDDR5 and LPDDR5X are two different types of memory technologies commonly used in mobile devices such as smartphones, tablets, and portable gaming consoles. One can easily guess that LPDDR5X is better than LPDDR5. But you need to understand how LPDDR5X is different from LPDDR5. In this detailed guide, I will explain LPDDR5 vs LPDDR5X. I will also provide you with additional details to tell you how LPDDR5X is better than LPDDR5.

LPDDR5

LPDDR5 is the 5th generation of the LPDDR memory standard offering higher data transfer and improved power efficiency compared to its predecessor, LPDDR4X. LPDDR5 supports data transfer rates of up to 6.4 Gbps. It uses 16-bit prefetch architecture for increased memory bandwidth. LPDDR5 RAM operates at a lower voltage (1.1V) for power efficiency. LPDDR5 also features burst length chopping that enables shorter bursts of data transfers for reducing power consumption. It also has a deep power-down mode for further power savings.

LPDDR5 was first introduced in early 2020 with Snapdragon 865. Initial devices with LPDDR5 could only run as speeds up 5500Mbps, but it was pushed to 6400Mbps of data rates in subsequent updates.

LPDDR5X

LPDDR5X is an enhanced version of LPDDR5 that offers even better performance. LPDDR5X supports speeds of up to 8.5 Gbps. It provides a boost in memory bandwidth as compared to LPDDR5. For achieving higher rates, LPDDR5X employs advanced signaling and equalization techniques. This helps in maintaining data integrity and signal quality. LPDDR5X operates at the same voltage of 1.1V as LPDDR5.

LPDDR5X vs LPDDR5

Now, let’s compare LPDDR5X and LPDDR5 in a table format:

Xiaomi M10 was the first smartphone that came with LPDDR5 RAM. This phone was released back in February 2020. Realme GT Master 2 was released back in July 2022 and the phone camera tip LPDDR5X RAM.
