Since its inception, AMD’s Ryzen CPU line-up for its notebook market are designed to support the current DDR4 memory standard, but not LPDDR4X. That might change very soon, as the latest Linux patches seem to suggest AMD’s next generation APUs will the low-power memory format and at high frequencies, to boot.
The APUs, which currently go by the codename Renoir, were mentioned in two separate Linux patches. The first reportedly mentions the APU’s codename and the LPDDR4X memory format, while the second patch mentions that it would be running at speeds of 4266MHz, which is significantly faster than what most notebook LPDDR4 memory chips operate at.
LPDDR4 is by no means new; the memory format was first introduced back in 2014. Back then, the memory format was only able to achieve a maximum frequency of 3200MHz. In 2017, LPDDR4X came on to the scene, introducing speeds as high as 4266HMz.

Most AMD notebooks on offer today run on regular DDR4-2400 memory. Those speeds are by no means slow, but it pales in comparison to the fast DDR4-3200 and LPDDR4-3733 memory formats that Intel’s new Ice Lake notebooks offer. That’s what makes Renoir so special; if the patches are to be believed, then AMD’s upcoming APU will be the first AMD integrated processor to support the LPDDR4X format.
Unfortunately, AMD is being coy about a specific launch date for Renoir, but rumours suggest that we could be seeing the processor as early as 2020. We’ll just have to wait and see.
