The Pixel 6’s Tensor processor guarantees to place Google’s machine studying smarts in your pocket

Google’s Pixel 6 and Pixel 6 Pro are formally right 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 preliminary 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 opponents.

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

Tensor additionally allows new Pixel 6 options like Motion Mode, extra correct face detection, and stay translations that may convert textual content to a unique language as shortly as you may kind it. Google additionally says that the Tensor chip will deal with devoted machine studying duties with way more energy effectivity than earlier Pixel telephones.

But 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 parts 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, two high-power Cortex-X1 cores, two midrange (rumored to be older Cortex-A76 cores), after which 4 low energy effectivity cores (probably Arm’s normal Cortex-55 designs). Graphics are provided by a 20-core GPU, along with a context hub that powers ambient experiences just like the always-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 fully 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 energy environment friendly). But it’s price noting that the Pixel 5’s Snapdragon 765G additionally used two Cortex-A76 cores for its essential CPU cores, so it’s doable 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 comparison with 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 comparison with different conventional Android flagships. Google’s CPU configuration is a singular one, in comparison with the extra conventional 4 high-performance and 4 effectivity cores utilized by main Qualcomm and Samsung chips.

In concept, 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 4 Cortex-A55 cores. But Google can be swapping out the 2 high-end cores with midrange ones, which can assist battery life and efficiency… or could end in a weaker total system. We’ll discover out quickly as soon as we’ve had the prospect to place the Pixel 6 and Tensor by way of their paces.
