Intel has released its new low-power x86 microprocessor architecture called Tremont, aimed at cheap laptops, dual-screen devices, and the Internet of Things (IoT), data center servers, and 5G networking equipment.

Intel Tremont processor enhancements will provide 30% more performance than Goldmont Plus

Tremont follows the iteration of Intel Goldmont's Atom microarchitecture, and is expected to appear in Lakefield's 10-nanometer processor intended for super-thin and light ultraportables like Microsoft's Surface Neo.

Lakefield is a hybrid design that uses Foveros 3D technology to stack four low-power Atom cores with a more powerful Core chip.

Tremont-based Atom cores will be used for less demanding background tasks, and the Core chip for more processor-intensive work, similar to current ARM-designed parts that compete with Intel in the low-power market.

Compared to previous Atom iterations, Tremont provides substantial instructions to improve performance per cycle, which are necessary for your low-power x86 processors to compete with AMD's Zen and Zen 2.

Increased cache size and new instructions

With Tremont, Intel is trying to cope with criticism of low processing power with new design features that improve single-threaded performance over Goldmont chips. There is talk of a performance improvement of at least 30%.

This is done by borrowing the class prediction technology from Intel's Core processors, and various instructions that have been added, such as CLWB, GFNI (based on SSE), ENCLV, and Split Lock Detection. These instructions will also be implemented in Ice Lake.

Tremont also features ten execution ports and dual load and storage pipelines for increased performance, along with L2 cache sizes up to 4.5 MB for quad-core modules. The power consumption for Tremont-based parts is designed to drop between 0.5 and 2 watts.

In terms of security, Intel's rooted security boot using Trusted Execution Technology and Boot Guard have been implemented, which fully encrypts data in memory.

Intel is hopeful that it will be much more competitive in the ultra-low power market with this new generation of processors. We'll see.
