“AMD stupidly canceled the ARM K12 processor after leaving the company”

Jim Keller, the famed microprocessor architect, who was behind the architectures that brought AMD Ryzen and Intel Alder Lake processors to life, is now making headlines after revealing at a conference that AMD has decided “stupidly cancel” your CPU project ARM K12 after leaving the company.

Although Jim Keller announced that he was behind the development of the Zen, Zen2 and Zen3 architectures, eventually all work on some ARM K12 cores was abandoned by AMD, which could cost them dearly if you look at what apple will do with the ARM architecture, and that other manufacturers follow the same approach, since everything indicates that in the future ARM, and even RISC-Vthey will seriously replace the current x86 architecture.

Without going any further, Intel has partnered with SiFive to promote the release of high-performance RISC-V platforms, or of course, as Jim Keller himself indicated a few months ago that if he wanted to make a PC today, I would choose the RISC-V architecture to create your processor.

ARM-based AMD K12 core

In this way, Jim Keller clarifies that the ARM K12 processor project was canceled after he left the company by some managers. As he says himself, most managers they are afraid to change thingsbut being an architect himself, he is not afraid of these kinds of changes and the work he did during his time at AMD was “funny“.

AMD K12 processors were originally going to arrive in 2017 based on the ARMv8 architecture, i.e. 3 years before that Apple Silicon’s first processor, the Apple M1, will reach the market. Now, without ARM-based processors, AMD is redesigning its x86 cores to try to compete in the same segment as ARM, and a clear example is the Zen4ca lowered Zen4 core in an attempt to compete with ARM in terms of energy efficiency in servers.
