Most smartwatches running Google’s Wear OS software that have shipped in recent years have been powered by Qualcomm Snapdragon Wear processors. But the new Samsung Galaxy Watch 4 that’s set to launch this week? It’ll be using Samsung’s brand new Exynos W920 processor instead.

Samsung says the new chip offers up to 20% faster CPU performance than its predecessors, and up to 10X better graphics. It’s also the first 5nm processor designed for wearables.

The new chip features two ARM Cortex-A55 CPU cores, ARM Mali-G68 graphics, and a low-power ARM Cortex-M55 co-processor that kicks in for always-on-display functions, letting you see the time and notifications without waking the watch from sleep mode.

The Exynos W920 also features a 4G LTE Cat 4 modem for cellular connectivity and support for GNSS/GPS navigation.

Other features include support for LPDDR4 memory, eMMC storage, and display resolutions up to 960 x 540 pixels.

Samsung isn’t the only company launching new wearable chips this year. Qualcomm introduced the Snapdragon Wear 4100 and 4100+ in June, promising memory, graphics, and connectivity improvements. But it’s the first updated from Qualcomm in two years and, at least on paper, Samsung’s new chip looks like it should be significantly more powerful.

Up until recently, Samsung hadn’t been a part of the Google Wear OS ecosystem. Instead the company used its own Tizen-based software for Galaxy Watch series devices. But Samsung and Google announced this year that they would launch a new unified platform known as Wear OS 3.

What’s interesting is that the Galaxy Watch 4 will likely be the first device to ship with the new software… and the only device to ship with the software for the foreseeable future. Google completed its acquisition of wearable activity tracker/smartwatch maker Fitbit this year, but has yet to launch any new wearables since closing the deal (unless you count wireless earbuds).

Meanwhile, the Apple Watch continues to dominate the wearable space year after year and it remains to be seen whether a Samsung-Google team-up, a new “unified” operating system, and newer, faster processors will do anything to change that.

  1. I need unix
    for example simple linux on device working week on 2 AA battery and small screen.

    super hiper cpu but still not for normal users

    1. About that. First, that’s not much related to this because this is a watch and two AA batteries will mean something larger.
      But if you’re looking for that, you will have to build it yourself because anyone who wants something like that will disagree on what hardware they want in it. You have said that a small screen and long battery life are most important, which is going to mean a slow processor and not very much comms. If that’s fine with you, you can build that from a number of cheap parts. If you want it to run quickly, have always-on WiFi, or use a more prebuilt board, you’re going to have problems with power management. Everyone has an idea of some very custom device that would be really useful for them, but most of us don’t agree on what we need in that useful device, which is why such things rarely get manufactured in large quantities.

  2. Typo:
    promising memory, graphics, a d connectivity improvements

    Should be:
    promising memory, graphics, and connectivity improvements
