LPDDR5 vs LPDDR5X Memory Differences: Up to 17GB/s of Bandwidth, 33% Faster

Micron and Samsung have each printed the specs of their next-gen LPDDR5 cell reminiscence. In comparison with LPDDR5, we’re taking a look at a efficiency enhance of 33%, and a voltage of 1.1v. Whereas LPDDR5 tops out at an information price of 6,400Mbps or 3,200MHz, LPDDR5X expands that determine to 8,533Mbps or 4,227MHz. The bus width stays the identical 16-bit (two per DIMM), whereas the prefetch and size of 16 are additionally retained.

The voltage stays dynamic, with a peak of 1.1v, and a Vddq of 0.6v. The banks have been elevated to 16, not like LPDDR5 which supported 8-16 banks per DIMM. The twin-channel structure has been retained as properly, permitting for 2 unbiased 16-bit channels per DIMM. Micron might be fabbing its LPDDR5X reminiscence chip on its 1α, fourth-generation 10nm manufacturing expertise. MediaTek estimates that LPDDR5X can attain 60GB/s when paired with the Dimensity 9000 SoC. The reminiscence itself can attain speeds near 70GB/s with future revisions.
