'''Goldmont Plus''' ('''GLM+''') is [[Intel]]'s [[14 nm]] [[microarchitecture]] of [[system on chip]]s for the ultra-low power (ULP) devices serving as a successor to {{\\|Goldmont}}. Goldmont Plus-based processors and SoCs are part of the {{intel|Atom}}, {{intel|Pentium Silver}}, and {{intel|Celeron}} families.

== Release Dates ==
Goldmont Plus processors were launched on December 11 2017 for desktop, mobile and embedded devices. Server-based parts are expected to be introduced in 2018.

== Technology ==
Goldmont Plus, like its predecessor is manufactured on Intel's original [[14 nm process]] (as opposed to 14nm+ or 14nm++).

== Compiler support ==
