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, which Google has lastly revealed extra data on what the brand new SoC can really do, for the quickest Pixel telephones ever.

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

That’s nonetheless the big focus of Google’s announcement at present: the corporate calls Tensor a “milestone for machine studying,” that the corporate co-designed alongside Google Analysis to permit the corporate to simply translate AI and machine studying advances into precise shopper merchandise. For instance, Google says that the Tensor chip can have “probably the most correct Automated Speech Recognition (ASR)” that Google’s supplied, for each fast Google Assistant queries and longer audio duties like stay captions or the Recorder app.

Tensor additionally permits new Pixel 6 options like Movement Mode, extra correct face detection, and stay translated textual content that may convert textual content to a unique language as rapidly as you possibly can kind it. Google additionally says that the Tensor chip will deal with devoted machine studying duties with much more energy effectivity than earlier Pixel telephones, too.

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 main elements that make Tensor tick.

As rumored, the Tensor chip makes use of a singular mixture of CPU cores. There’s the customized TPU (Tensor Processing Unit) for AI, and two high-power Cortex-X1 cores, two mid-range rumored to be older Cortex-A76 cores), after which 4 low energy effectivity cores (doubtless Arm’s ordinary Cortex-55 designs.) Graphics are supplied by a 20-core GPU, along with a context hub that powers ambient experiences just like the all the time on show, a non-public laptop 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 solely clear why Google would select to make use of the Cortex-A76 cores as an alternative of the extra fashionable Cortex-A78 (that are each extra highly effective and extra power-efficient), however it’s price noting that the Pixel 5’s Snapdragon 765G additionally used two Cortex-A76 cores for its predominant CPU cores, so it’s doable Google is sticking with what it is aware of.

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

The true query, although, is how the Pixel 6 and its Tensor chip maintain up in comparison with different conventional Android flagships. Google’s CPU configuration is a singular one, in comparison with the extra conventional 4 excessive efficiency and 4 effectivity cores utilized by main Qualcomm and Samsung chips.

In principle, Google is providing double the variety of X1 efficiency cores — probably 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 also be swapping out the 2 high-end cores with mid-range ones, which can assist battery life and efficiency… or could end in a weaker general machine. We’ll discover out quickly as soon as we’ve had the prospect to place the Pixel 6 and Tensor by means of their paces.

Creating… we’re including extra to this submit, however you possibly can observe together with our Pixel 6 event live blog to get the information even quicker.
