'''eMAG''' is a family of {{arch|64}} high-performance [[ARM]] server microprocessors designed by [[Ampere Computing]] for the data center.

== Overview ==
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.

=== 1st Gen ===
{{see also|apm/microarchitectures/skylark|l1=Skylark µarch}}
First generation eMAG processors are based on the {{ampere|Skylark|l=arch}} microarchitecture, a design that started out by [[AppliedMicro]]. Fabricated on [[TSMC]]'s [[16 nm process|16FF+ process]], those processors feature up to 32 cores operating at up to 3.3 GHz.

* '''Mem:''' 8x DDR4 channels, up to 2666 MT/s with ECC; 1 TiB/socket
* '''I/O:''' 42 PCIe Gen 3 lanes
* '''TDP:''' Up to 125 W

== 2nd Gen ==
{{see also|ampere computing/microarchitectures/quicksilver|l1=Quicksilver µarch}}
Second generation eMAG processors are planned for 2019. Those chips will be based on Ampere's {{ampere|Quicksilver|l=arch}} microarchitecture and feature an array of new features and improvements.
