Rumor Alert: AMD’s Renoir APUs to support LPDDR4X- 4266 MHz memory

Rumor has it: AMD’s next-gen APUs, code-named, Renoir, might feature support for LPDDR4X memory as fast as 4266 Mhz. Renoir is rumored to arrive in 2020 with Zen 2 cores. The next-gen APUs will also leap to 7nm, like their graphics-less counterparts already have. These APUs are heavily anticipated by consumers. 

This rumor comes courtesy of two Linux patches- the first and the second– that mention LPDDR4X and the aforementioned frequency, respectively. This is not unlikely, as Intel has just rolled out upgraded memory controllers in both Ice Lake and Comet Lake-U parts, and a response by AMD should be expected. Ice Lake features support for LPDDR4X up-to 3733 MHz and Comet Lake-U up to 2933 MHz. Moreover, Ice Lake features vastly overhauled Gen11 graphics delivering up to 1 Teraflop of performance, which compete favorably with AMD’s current Picasso APUs. It would make all the sense in the world for AMD to launch its next-gen APUs with overhauled IMCs (integrated Memory Controllers). 

German outlet ComputerBase and habitual hardware leaker Komachi_Ensaka were among the first to spot the leak in the Linux patches. 


An earlier leak from a Linux patch had indicated that Renoir is going to stick with Vega graphics, Vega 10 to be exact. That’s a bit disappointing, but at least faster memory should provide better graphics performance as APUs are heavily dependent on memory bandwidth because they lack dedicated video memory. Renoir is supposed to be the successor to Picasso and is slated to arrive sometime in 2020, although this has not been confirmed by AMD.
