Google’s next Pixels will reportedly switch to a custom in-house GS101 processor


Google’s next Pixel flagship — the presumably named “Pixel 6” — will reportedly characteristic a Google-designed GS101 “Whitechapel” SoC (system on a chip), a first for the corporate, as reported by 9to5Google and XDA-Developers.

9to5Google’s report claims Google is engaged on two telephones that will characteristic the Arm-based GS101 — presumed to be a flagship system to succeed final 12 months’s Pixel 5 and a Pixel 4A 5G follow-up.

XDA’s report, in the meantime, goes into additional element on the brand new SoC, claiming the GS101 chips will characteristic a “three cluster setup with a TPU (Tensor Processing Unit)” for machine studying purposes. (For reference, Qualcomm’s personal flagship Snapdragon 888 makes use of Arm’s Cortex-X1 / Cortex-A78 / Cortex-A55 as a triple cluster CPU setup.) Additionally, the brand new SoC might characteristic an built-in safety chip, comparable to the Titan M.

The concept of Google making a custom TPU or safety chip isn’t new: Google has beforehand made TPUs for servers and the Pixel 4’s Neural Core, together with the discrete Titan M chip on its present telephones. But the custom-designed GS101 would presumably permit the corporate to combine these options on a deeper degree.

Rumors of the Whitechapel chips have circulated since final 12 months when Axios reported that Google was wanting to develop its personal in-house chips to be used in Pixel and Chromebook gadgets. That report claimed the corporate can be optimizing its chip for Google’s machine studying expertise — one thing the XDA report corroborates. The GS101 chip for the 2021 Pixel lineup can be the primary fruits of the Whitechapel mission, though Axios’ authentic report famous that Chromebook chips weren’t anticipated till additional sooner or later.

9to5Google’s report additionally contains references to a “Slider” codename tied to the brand new system, which it says can also be linked to Samsung’s Exynos SoCs (which the corporate makes use of on Galaxy smartphone gadgets outdoors the US). Samsung’s involvement on the manufacturing aspect — which Axios additionally reported final 12 months — would make sense, as one of many largest producers of smartphone semiconductors.

The concept of Google-designed chips is a compelling one. Apple has lengthy touted its tightly built-in software program and {hardware} stack as a key a part of how its iPhones, iPads, and now, its Mac computer systems are in a position to run so properly — a key a part of which is the corporate’s custom-designed A-series and M-series chips.

Google — and nearly each different Android producer, save Samsung and Huawei — doesn’t have that benefit. It as a substitute depends on Qualcomm’s Snapdragon chips, which dominate the Android market within the US. Oftentimes, an Android system lives or dies on how properly its producer is in a position to synergize Qualcomm’s chips, Google’s software program, and its personal {hardware} designs. Similarly, the truth that, at their core, nearly each Android system runs on the identical chipset and the identical software program makes it troublesome for anybody mannequin to stand out.

But a Google-designed GS101 chip brings a tantalizing promise: that Google may carry an Apple-like increase in velocity, efficiency, and battery life to Android (and particularly, its Pixel lineup) with a comparable degree of management over the {hardware} design, software program, and processor. It’s an intriguing concept — assuming Google can pull it off.

That mentioned, constructing a smartphone processor on the degree of Apple or Qualcomm isn’t straightforward. While each corporations use Arm as a frequent base, they’ve spent years refining these fundamental constructing blocks with customizations to go well with their wants. Apple has been utilizing custom designs in its processors because the 2012’s A6 design (as opposed to earlier fashions that used licensed CPU designs from Arm itself). Qualcomm takes a comparable method in its fashionable processors, utilizing custom Kryo cores which can be semi-customized variations of Arm’s base Cortex designs.

It may take Google a few generations to fine-tune its Pixel chips. But if Google can really ship on a correct custom-made chip that’s constructed from the bottom up to be particularly designed for Android’s software program and the Pixel’s {hardware}, it may very well be the important thing to remodeling the Pixel line from a sideshow to a true smartphone powerhouse.
