Goldmont Plus
Goldmont Plus is a microarchitecture for low-power Atom, Celeron and Pentium Silver branded processors used in systems on a chip (SoCs) made by Intel. The Gemini Lake platform with 14 nm Goldmont Plus core was officially launched on December 11, 2017. Intel launched Gemini Lake Refresh platform on November 4, 2019.

Design
Goldmont Plus is an enhanced 2nd generation out-of-order low-power Atom  microarchitecture designed for the entry level desktop and notebook computers. Goldmont Plus is built on the 14 nm manufacturing process and supports up to four cores for the consumer devices. It includes the Intel Gen9 graphics architecture with improvements introduced with the Kaby Lake microarchitecture.

The Goldmont Plus microarchitecture builds on the success of the Goldmont microarchitecture, and provides the following enhancements:

 Widen previous generation Atom processor back-end pipeline to 4-wide allocation to 4-wide retire, while maintaining 3-wide fetch and decode pipeline.
 Enhanced branch prediction unit. 
 64 KB shared second level pre-decode cache (16 KB in Goldmont microarchitecture).
 Larger reservation station and re-order buffer entries to support large out-of-order window. 
 Wider integer execution unit. New dedicated JEU port with support for faster branch redirection.
 Radix-1024 floating point divider for fast scalar/packed single, double and extended precision floating point divides. 
 Improved AES-NI instruction latency and throughput.
 Larger load and store buffers. Improved store-to-load forwarding latency store data from register.
 Shared instruction and data second level TLB. Paging Cache Enhancements (PxE/ePxE caches). 
 Modular system design with four cores sharing up to 4 MB L2 cache.
 Support for Read Processor ID (RDPID) new instruction.
