According to a well-known source @Mauri QHD, AMD is working on a rival to apple’s M1 chip, which currently has two prototypes, one with integrated memory and one without.
According to foreign media NoteBookCheck, AMD released a K12 chip based on 64-bit ARM V8 in 2016 when Jim Keller was at AMD. However, the chip never made it to market. Earlier this year, whistleblower Komachi exposed AMD’s road map, which also listed the “K12 FFX” entry. Assuming the “K12 FFX” chip actually exists, it could be for ultra-low-power laptops and other mobile devices.
Not long ago, IT House learned, AMD’s patents for “a subset of instructions for low-power operations” had surfaced, which assumed several hybrid processor designs for mobile devices. While it is unclear whether these designs are for x86 or ARM, they do indicate that a new low-power CPU architecture is indeed being developed in AMD’s LABS.
