Memory Hierarchy[edit]
- Cache
- Hardware prefetchers
- 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

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.
