X-Gene was a family of 64-bit ARM server microprocessors designed and introduced by AppliedMicro.

Overview

X-Gene was a family of high-performance multi-core ARM microprocessors first announced by AppliedMicro in 2011. Unlike their traditional product offering, X-Gene directly targeted high-performance data center servers, a market predominantly dominated by Intel Xeon processors. AppliedMicro introduced two generations of server processors based on their own custom ARM microarchitectures - Storm and Shadowcat. Those two generations shipped a total of 25,000 units. In late 2016, MACOM acquired AppliedMicro resulting in the shelving of third-generation X-Gene based on the Skylake microarchitecture. The X-Gene intellectual property including most of the design team was eventually sold to Ampere Computing has rebranded the design and improved on it under the eMAG brand.
