Goldmont Processor

What is Goldmont Processor?

The term Goldmont refers to the low-power Pentium, Celeron and Atom branded CPUs used in Systems on a Chip (SoCs) designed for use in smaller devices such as entry-level notebooks and desktop computers.

Technically, it signifies the 2nd generation low-power, Out-of-Order Atom microarchitecture. Designed and manufactured by Intel, the Goldmont microarchitecture officially supports only one thread in each core and is built on the 14 nm manufacturing process.

Understanding Goldmont Processor

What is Goldmont Processor

Designed by Intel, the Goldmont processors belong to the 2nd generation of low-power Celeron, Pentium, and Atom families and come with a SoC design.

This particular architecture comes with a lot of features similar to those of the Skylake Core processors.

These features enable the Goldmont processors to offer a performance boost of up to 30% in comparison to the previous generations.

The features and functionalities of the Goldmont processors allow them to be used in low-end, smaller devices where power efficiency is most important. These devices include:

Typically, the Goldmont processors come with three decoder units that can decode a maximum of 20 bytes in one cycle.

These decoders are triple-wide and can retire up to three instructions in one cycle, while the chip itself can execute one load and store in each clock cycle.

When coupled together, they offer a significant higher and faster performance overall.

Ideally, the processors based on the Goldmont architecture come in different variants such as:

Normally, Apollo Lake cores are used in entry-level computers and tablets, and Denverton cores are used in ultra-low power servers, storage, networking, and the Internet of Things (IoT).

Features and technology

The architecture of the Goldmont processors offers a lot of significant enhancements due to its innovative features and different technologies. These are summarized for you as follows:

Integrated graphics processor

The Goldmont processors come with Intel Gen 9 HD Graphics. Depending on the driver installed in the system, these graphics processors support a wide range of features such as:

Ideally, the Gen 9 HD Graphics 400 and HD Graphics 500 come with 12 Execution Units, while in comparison, the HD Graphics 405 and HD Graphics 505 come with 18 Execution Units.

Memory subsystem

The memory hierarchy of the Goldmont processors consists of Level 1 and Level 2 cache but no Level 3 cache. The Level 1 cache is divided into two parts for data and instructions and s with varied features.

The Level 1 instruction cache comes with the following features:

The Level 1 data cache comes with the following features:

The Level 2 cache comes with the following features:

There may also be a few Paging Cache Enhancements or PxE/ePxE caches, depending on the type.

The modular system design, or the processors with four cores, allowing sharing the Level 2 cache up to 4 MB.

The Random Access Memory or RAM support offered may be different due to the dual 32-bit channels supporting one or two ranks in one channel. The memory limit supported can be up to:

Pipeline

The features of the pipeline supported by the Goldmont processors are as follows:

Instruction Sets and Extensions Support

The Goldmont x86 architecture supports x86-64 or Intel-64 Instruction Set Architecture (ISA) and different old and new extensions of theirs, such as:

Conclusion

The Goldmont processors may not offer huge gains over the earlier generations, but the uplift in performance is quite noticeable.

The transition is quite worthy, and it is even better in Goldmont Plus, its successor.

Typically, as you can see from the features, these CPUs are good for low power mobile and desktop use.
