| − | '''Goldmont Plus''' ('''GLM+''', '''GLP''') 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.

| |
| − | == Architecture ==
| |
| − | Despite the name "Goldmont Plus", this microarchitecture is a very large implementational jump from "Goldmont" with improvements across the board from the caches to a wider pipeline.

| |
| − | === Multithreading ===
| |
| − | Goldmont Plus, like {{\\|Goldmont}} has no support for Intel Hyper-Threading Technology.
| |
| − |
| |
| − | == New Integration ==
| |
| − | === Integrated Connectivity (CNVi) ===
| |
| − | {{main|intel/cnvi|l1=CNVi}}
| |
| − | A new integration to Goldmont Plus is '''Integrated Connectivity''' ('''CNVi''') which is an architecture for wireless connectivity devices. CNVi attempts to simplify vendors bill of material (BOM) size and cost by integrating the majority of the expensive functionality found in an RF chip. The only thing not integrated are the actual analog and RF functions which come from a relatively inexpensive companion RF (CRF) module connected via a standard [[M.2]] card and provides support for things such as [[IEEE 802.11ac]].
