ARM announced the K12 core as early as 2014, which is based on the 64-bit ARMv8 architecture, and said it plans to launch related processors in two years. This product is positioned in areas such as high-density servers, embedded, semi-custom, and ultra-low power consumption, but it has not been officially launched.
In 2020, in addition to Intel’s ultra-low power Y and Lakefield series, Qualcomm and Apple have also released 8cx and M1 chips respectively. Although AMD performs well in most mainstream markets, it has always lacked ultra-low-power chip products.
But now there is news that AMD is designing a processor based on the ARM architecture to benchmark the Apple M1. There are currently two prototype chips, one of which has integrated memory. In the middle of this year, some whistleblowers said that K12 FFX items were found in AMD’s roadmap. If it really exists, then it should be prepared for ultra-low-power laptops and tablets.
At the same time, AMD’s patent on “instruction set for ultra-low power operation” also surfaced not long ago. These instruction sets are specifically for ultra-low voltage chips, but it is still uncertain whether they are for x86 or ARM.
What is certain is that AMD’s related products should also adopt large and small core designs similar to 8cx and M1. But according to AMD’s style, I think there should be at least 8 large cores.
