eMAG is a family of 64-bit high-performance ARM server microprocessors designed by Ampere Computing for the data center.

Overview[edit]

eMAG is a family of high-performance ARM server processors designed by Ampere Computing and introduced in 2018. Ampere's introduction of eMAG to the market concludes the design that started out by AppliedMicro. eMAG processors targets server workloads capable of taking advantage of a high core count with high throughput.
