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 function a Google-designed GS101 “Whitechapel” SoC (system on a chip), a first for the corporate, as reported by 9to5Google and XDA-Builders.

9to5Google’s report claims Google is engaged on two telephones that will function the Arm-based GS101 — presumed to be a flagship machine 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 function a “three cluster setup with a TPU (Tensor Processing Unit)” for machine studying functions. (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.) Moreover, the brand new SoC might function an built-in safety chip, related 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. However the custom-designed GS101 would presumably permit the corporate to combine these options on a deeper stage.

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

9to5Google’s report additionally consists of references to a “Slider” codename tied to the brand new machine, which it says can be related to Samsung’s Exynos SoCs (which the corporate makes use of on Galaxy smartphone units 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 nicely — 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 an alternative depends on Qualcomm’s Snapdragon chips, which dominate the Android market within the US. Oftentimes, an Android machine lives or dies on how nicely its producer is ready to synergize Qualcomm’s chips, Google’s software program, and its personal {hardware} designs. Equally, the truth that, at their core, nearly each Android machine runs on the identical chipset and the identical software program makes it troublesome for anybody mannequin to stand out.

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

That stated, constructing a smartphone processor on the stage of Apple or Qualcomm isn’t simple. Whereas each firms use Arm as a widespread base, they’ve spent years refining these fundamental constructing blocks with customizations to swimsuit 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 related strategy in its fashionable processors, utilizing custom Kryo cores which can be semi-customized variations of Arm’s base Cortex designs.

It would take Google a few generations to fine-tune its Pixel chips. But when 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 might be the important thing to reworking the Pixel line from a sideshow to a true smartphone powerhouse.
