The Pixel 6’s Tensor processor promises to put Google’s machine learning smarts in your pocket

Google’s Pixel 6 and Pixel 6 Pro are officially here, and with them, the debut of Google’s new Tensor chip. Google has lastly revealed extra info on what the brand new SoC can really do, for the quickest Pixel telephones ever.

The initial reveal of the Pixel 6 and the Tensor chip was largely centered on its AI-focused TPU (Tensor processing unit) and the way the customized {hardware} would assist Google differentiate itself from rivals.

That’s nonetheless the big focus of Google’s announcement in the present day: the corporate calls Tensor a “milestone for machine learning” that was co-designed alongside Google Analysis to enable it to simply translate AI and machine learning advances into precise client merchandise. For instance, Google says that the Tensor chip could have “essentially the most correct Computerized Speech Recognition (ASR)” that it’s provided, for each fast Google Assistant queries and longer audio duties like reside captions or the Recorder app.

Tensor additionally permits new Pixel 6 options like Movement Mode, extra correct face detection, and reside translations that may convert textual content to a distinct language as rapidly as you possibly can sort it. Google additionally says that the Tensor chip will deal with devoted machine learning duties with way more energy effectivity than earlier Pixel telephones.

However there’s much more to a smartphone chip than its AI chops, and with the reveal of the Pixel 6, we lastly have extra particulars on the relaxation of the chip, together with the CPU, GPU, modem, and the most important elements that make Tensor tick.

As rumored, the Tensor chip makes use of a novel mixture of CPU cores. There’s the customized TPU (Tensor Processing Unit) for AI, two high-power Cortex-X1 cores, two midrange (rumored to be older Cortex-A76 cores), after which 4 low energy effectivity cores (seemingly Arm’s common Cortex-55 designs). Graphics are provided by a 20-core GPU, in addition to a context hub that powers ambient experiences just like the always-on show, a non-public pc core, and a brand new Titan M2 chip for safety. There’s additionally a devoted picture processing core to assist with the Pixel’s hallmark images.

It’s not fully clear why Google would select to use the Cortex-A76 cores as a substitute of the extra fashionable Cortex-A78 (that are each extra highly effective and extra energy environment friendly). However it’s price noting that the Pixel 5’s Snapdragon 765G additionally used two Cortex-A76 cores for its major CPU cores, so it’s attainable Google is sticking with what it is aware of.

The new telephones ought to nonetheless be the quickest Pixel telephones but, with Google promising 80 p.c quicker CPU efficiency in contrast to the Pixel 5, and 370 p.c quicker GPU efficiency.

The actual query, although, is how the Pixel 6 and its Tensor chip maintain up in contrast to different conventional Android flagships. Google’s CPU configuration is a novel one, in contrast to the extra conventional 4 high-performance and 4 effectivity cores utilized by main Qualcomm and Samsung chips.

In idea, Google is providing double the variety of X1 efficiency cores — essentially the most highly effective Arm design — than the Snapdragon 888 or Exynos 2100, which each use a single Cortex-X1, three Cortex-A78, and four Cortex-A55 cores. However Google can be swapping out the 2 high-end cores with midrange ones, which can assist battery life and efficiency… or may end result in a weaker general machine. We’ll discover out quickly as soon as we’ve had the prospect to put the Pixel 6 and Tensor by their paces.
