Intel has released its new low-power solution in full today (October 24, 2019). It is an x86 microarchitecture associated with "significant" IPC enhancements compared to its predecessor. Tremont can also support an L2 cache of up to 4.5MB, as well as crypto acceleration that includes dual 128-bit AES units. It is pitched at IoT, server, client and connectivity applications.

The new Intel microarchitecture for chipsets that may include the new Lakefield SoC slated for the innvoative Microsoft Surface Neo has been unveiled as promised during the Linley Group's latest conference. This new solution, known as Tremont, is an x86 platform like its predecessor Goldmont Plus. However, its maker asserts that it has many advantages over this older solution.

Tremont now supports new features such as Intel Speed Shift, for improved hardware-based frequency fluctuations; Trusted Execution Technology; Boot Guard for secured boot; Total Memory Encryption and an updated method of syncing to accelerators.

The new ultra-low power solution also has an L2 cache rated for 1.5 to 4.5MB, which can be spread across between 1 and 4 cores. Its last-level cache is both inclusive and non-inclusive. Tremont also integrates Intel Resource Directory Technology with memory bandwidth enforcement and L2 quality-of-service (QoS), which extends to code and data prioritization.

Tremont's 6-wide decoding front end sports an out of order fetch with a 32 kilobit instruction cache featuring 32 bytes per cycle and up to 8 outstanding misses. This end also has a Core-class branch predict, whereas the back end is a 10-wide execution port.

The new architecture's vector execution also comprises 3 ports; dual 128b AES units; single instruction SHA256 and Galois Field crypto acceleration. All in all, Intel asserts that these features render silicon based on Tremont more than ready for an extensive range of applications, such as integration into data-centers, 5G networks and microservers.

I became a professional writer and editor shortly after graduation. My degrees are in biomedical sciences; however, they led to some experience in the biotech area, which convinced me of its potential to revolutionize our health, environment and lives in general. This developed into an all-consuming interest in more aspects of tech over time: I can never write enough on the latest electronics, gadgets and innovations. My other interests include imaging, astronomy, and streaming all the things. Oh, and coffee.
