Intel's new Atom Microarchitecture: The Tremont Core in Lakefield

While Intel has been discussing a lot about its mainstream Core microarchitecture, it can become easy to forget that its lower power Atom designs are still prevalent in many commercial verticals. Last year at Intel's Architecture Summit, the company unveiled an extended roadmap showing the next three generations of Atom following Goldmont Plus: Tremont, Gracemont, and 'Future Mont'. Tremont is set to be launched this year, coming first in a low powered hybrid x86 design called Lakefield for notebooks, and using a new stacking technology called Foveros built on 10+ nm. At the Linley Processor Conference today, Intel unveiled more about the microarchitecture behind Tremont.

[...] The Atom core within a given family is usually identical (L2 [cache] configuration might change), and because of the SoC in play, it might get a different name based on the market where it was headed. Intel scrapped the smartphone program back with Broxton in 2016, and the tablet type of SoC has also gone away. With Lakefield, combining Core and Atom, it could be used in Tablets again for 2019/2020, but we will see it in Notebooks with the Surface Pro Neo and in networking/embedded markets as Snow Ridge.

[...] The interesting thing here in our briefing with Intel is that they specifically stated that Tremont was built with performance in mind, and the aim was for a sizeable uptick in the raw clock-for-clock throughput compared to the previous generation Atom, Goldmont Plus. Based on Intel's own metrics, namely using SPEC, Intel is going to claim an average 30% iso-frequency performance uplift in core performance for Tremont over Goldmont Plus. It's worth noting here that this data is from an early Tremont design we were told, and should represent minimum uplifts.

[...] A 30% average jump in performance is a sizeable jump for any generation-to-generation cadence. Just taking it as-is feels premature: aside from microarchitectural advancements and a jump to 10nm, there has to be something at play here – either the power budget of Atom has ballooned, or the die area. With Intel explicitly out of the gate stating that their focusing on performance, a cynic is going to suggested that something else has paid that price, and to that end Intel wasn't prepared to talk about power windows or die area, though they did point to the already announced Lakefield CPU, which has a 1 x Core + 4 x Tremont design

Intel wants back in the tablet space with its new Tremont architecture

Intel is unveiling its new "Tremont" ultra-low-power 10nm CPU architecture today at the Linley Fall Processor Conference in Santa Clara. Intel's presentation on the new architecture says that usage will "span client, IoT, and datacenter products." It's a little too early for a laundry list of the actual devices that will be powered by Tremont, but we do know that the new dual-screened Surface Neo is among them; its Lakefield hybrid processor uses both high-powered Ice Lake and low-powered Tremont cores.

Tremont is the successor to last year's Goldmont Plus, and Goldmont and Silvermont before it. These are the lowest-powered (and frequently, least expensive) CPUs in Intel's lineup, and consumers will generally be more familiar with them by names like Celeron and Pentium N. You could occasionally find Celeron or Pentium N processors in extremely low-end retail generic Windows PCs, but they were more frequently seen in specialty items like the bare Linux router build we showed off back in 2016.

    Just let it die already!

    Too strong to die anymore with that 30% performance increase.

    Slap on a single "Core" for high performance, and four Atom cores for multi-threaded. That's Lakefield. Arguably the most technically advanced processor Intel has ever made.

      If it can't die, then how about its management engine puts it to sleep never to wake up until kissed by a prints.
