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 Skylark 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.

Members
X-Gene 1
- See also: Storm microarchitecture
First-generation of X-Gene processors were announced in October 2011 and later launched in late 2012. X-Gene 1 processors are based on the Storm microarchitecture and were fabricated on TSMC's 40 nm process. Those processors had up to four memory channels and up to eight cores operating at up to 2.4 GHz.
- Mem: up to 4 memory channels, DDR3 @ up to 1866 MT/s
- Tech: ARMv8 (ARMv8.0-A)
- I/O: 17 PCIe, SATA/SGMII, 2x SGMII/XFI, 1x RGMII

X-Gene 2
- See also: Shadowcat microarchitecture
Second-generation of X-Gene processors were announced in September 2014 and later launched in early 2015. X-Gene 2 processors are based on the Shadowcat microarchitecture and were fabricated on TSMC's 28 nm process. Though those processors were more of a refresh over their predecessor, the new process technology produced lower-power chips at similar performance. Those processors had up to four memory channels and up to eight cores operating at up to 2.4 GHz.
- Mem: up to 4 memory channels, DDR3 @ up to 1866 MT/s
- Tech: ARMv8 (ARMv8.0-A)
- I/O: 17 PCIe, SATA/SGMII, 2x SGMII/XFI, 1x RGMII
