The LPDDR5T vs LPDDR5X is a difference of 13% speed in favor of the 5T. Smartphones like the vivo X100 series are the first to feature the LPDDR5T RAM technology.
LPDDR5T runs at 9.6Gbps speed compared to 8.5Gbps for LPDDR5X. At this speed, the latest RAM can go through 77GB worth of data in one second.
The LPDDR5T is not a new generation of DRAM but rather it’s an upgraded version of the LPDDR5/5X versions. The “T” in the LPDDR5T stands for “Turbo”.
Sk Hynix uses the HKMG (High-K Metal Gate) process that reduces power consumption and increases speed. LPDDR5T is the “world’s fastest mobile DRAM”, and that’s on period.
