DDR6 memory will reach 17.6Gbps speeds

A newly found JEDEC presentation reveals new details about Low Power Double Data Rate 6 (LPDDR6) memory. The upcoming standard is set to offer data speeds of 10.6Gbps and a bandwidth of 32Gbps in its introductory phase. Still, these values are expected to increase with later iterations of the memory. Additionally, we also have some details on the performance targets for DDR6 memory. 

Darkmont's presentation (via VideoCardz) mentions the increasing demand for faster bandwidth, particularly in light of the evolving integrated graphics systems that heavily rely on fast system memory. With Samsung and SK Hynix's mid-product updates (LPDDR5X and LPDDR5T) no longer meeting the industry's needs, the impending release of LPDDR6 is expected to solve this deficit.

JEDEC's projection for the LPDDR6 standard indicates a maximum specified data rate of 14.4Gbps, showcasing the ambitious goals set for this new technology. Initially, products will offer a maximum bandwidth of 32Gbps, but that value will “eventually” increase to 38.4Gbps (14.4Gbps memory speed).

In addition to LPDDR6, the DDR6 standard is also undergoing an upgrade, with JEDEC working to finalise the specifications by Q2 2025. The proposed data rates for DDR6 currently range from 8.8Gbps to 17.6Gbps, but there is potential for this to increase to 21Gbps.
