AMD CEO Rory Read has announced that the company intends to develop dense computing platforms based on the 64-bit ARM architecture today. This is the second major collaboration between AMD and ARM; Sunnyvale announced earlier this year that it would integrate an ARM core to provide additional hardware-level security on future APUs.
The meat of AMD's announcement today is that it's going to leverage the SeaMicro acquisition of earlier this year to ensure it has a platform for its own products. SeaMicro's Freedom Fabric virtualizes a great deal of technology that's normally built into hardware on a typical motherboard and reportedly saves a great deal of power and improves server density by doing so.
It's an announcement that raises as many questions as it answers. The good news is that AMD is scarcely alone in eyeing the ARM server market; there are a number of companies considering whether such a move makes good sense for them, as well. The 64-bit ARMv8 architecture looks solid, and low power is a hot market in every segment.
