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

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

- L1 Cache:
- 32 KiB 8-way set associative instruction, 64 B line size
- 24 KiB 6-way set associative data, 64 B line size
- Per core
- L2 Cache:
- 2 MiB 16-way set associative, 64 B line size

Multithreading[edit]
Goldmont Plus, like Goldmont has no support for Intel Hyper-Threading Technology.
New Integration[edit]
Integrated Connectivity (CNVi)[edit]
- Main article: 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.
