All the things we all know concerning the Pixel 7’s chip

We all know rather a lot concerning the upcoming Google Pixel 7 and Pixel 7 Professionalhowever the chipset that can energy these telephones stays just a little mysterious. Whether or not it was a profit or a curse, Google’s sticking with its customized chips, and the Pixel 7 ought to debut a brand new incarnation of Tensor with the GS201. And, like final yr, what little we do know is fairly uncommon.

Up to now, leaks for the upcoming GS201 Tensor have not occurred on the identical charge they did for the unique Tensor chipset. By simply April of 2021, we knew rather a lot concerning the authentic GS101however Google has managed to maintain a tighter ship this yr, limiting how a lot we and plumping out the spec desk with loads of “unknown” labels.



For people who simply need a desk, right here you go:

Dev board code title Cloudripper
Mannequin quantity GS201
Colours 2x “super-big”, 2x huge, 4x small Cortex-A55
GPU Unknown
Manufacturing node 4nm Samsung PLP
Modem g5300b
Different options Unknown

The second-gen Tensor GS201 might be made by Samsung on its 4nm node utilizing what’s known as panel-level packaging. It is a difficult approach of claiming the chips might be carved out of a sq. wafer relatively than a spherical one, lowering waste. This seemingly will not have a lot affect on the chip’s efficiency in precise gadgets, however it’s nifty and may scale back prices – doubtlessly helpful after we’re nonetheless in the course of a chip scarcity.

In response to some latest diving into the boot logs of a Pixel 7 Professional prototype, the GS201 Tensor should still maintain the two + 2 + 4 core cluster configuration that the unique Tensor GS101 used, with two “super-big” cores, two extra typical huge cores, and 4 small cores. Particulars within the logs point out that the small cores within the GS201 Might nonetheless be Cortex A55s, given the log makes a word of a workaround applied particularly for them. These are the identical small cores used within the authentic GS101 Tensor chipset and a design that dates again to 2017.

It is unclear what design the opposite cores within the GS201 may be. The last-gen Tensor used ARM Cortex-X1s for its “super-big” cores and A76s for its huge cores. With chipset rivals having since moved on to the X2, we may see X2s for the massive cores within the GS201, although that hasn’t been confirmed, and there are a number of generations of core designs Google or Samsung may select to switch the A76 in the event that they selected to.

Unsurprisingly, the GS201 might be paired with a Samsung-made modem once more, in response to particulars divined in earlier teardowns. The precise mannequin noticed this time is the g5300b. If Samsung follows the identical naming conventions it did on the Prior Tensor, this may be tied to an Exnyos Modem 5300 variant, which hasn’t been formally introduced but.

Mass manufacturing for the chipset is anticipated to start in June 2022in response to one report.

Different options

Smartphone chipsets aren’t only a listing of cores; different particulars inside them can have an effect on efficiency. One of many greatest causes that Google elected to create its personal chipset with the unique Tensor was for enhanced machine studying functions. With the rise of ambient computing, so-called heterogeneous compute – which implies pushing specialised workloads to completely different or custom-made items of {hardware} relatively than simply general-purpose CPUs – arguably has an even bigger affect on perceived gadget efficiency than huge single-threaded positive factors. It isn’t nearly one or two huge benchmarks, however how we really use our telephones. Increasingly, that is for issues like speech recognition, translation, fancy digital camera options, AR / VR, and different extra extremely specialised workflows. And for that, you want greater than a handful of latest ARM cores and a GPU.

The unique Tensor included components of Google’s HDRNet picture processing pipeline in {hardware}, offering extra specialization and direct efficiency for Google’s workloads than a common objective ISP can. Google additionally gave it a devoted safety core (paired with a separate Titan M2 chip operating “Trusty OS”). Whereas particulars like these have not leaked for GS201 but, you’ll be able to seemingly guess that Google will proceed so as to add these kinds of extremely specialised modifications. In spite of everything, options like these are your entire motive why an organization would choose to create a customized smartphone chipset. In any other case, Google would have simply used one thing from Qualcomm, because it did up to now.

Particulars have not leaked but, the GS201 will virtually actually have additional optimizations and enhancements in Google’s heterogeneous compute technique, implementing different new digital camera and machine studying options in {hardware} the place they are often finished extra shortly and effectively. At I / O, all Google stated concerning the upcoming chipset was that it’s going to deliver “much more AI-heavy breakthroughs and useful personalised experiences throughout speech, images, video, and safety.” And whereas the unique GS101 Tensor was closely primarily based on Samsung’s Exynos designs, we would see future fashions, just like the GS201, diverge from this base over time and as Google’s necessities change.

It is also value declaring that Google’s 2 + 2 + 4 core configuration is exclusive. Up to now, different chipset producers have not adopted in Google’s footsteps by together with multiple “super-big” core. In an interview with Ars Technica’s Ron Amadeo, Google’s Phil Carmack (VP and GM of Google Silicon) stated that this particular configuration was chosen to extend effectivity at “‘medium’ workloads” by with the ability to throw extra sources at a activity to do it shortly, returning to a low-power state quicker:

“When it is a steady-state downside the place, say, the CPU has a lighter load however it’s nonetheless modestly important, you may have the twin X1s operating, and at that efficiency stage, that would be the best … You may use the 2 X1s dialed down in frequency in order that they’re ultra-efficient, however they’re nonetheless at a workload that is fairly heavy. A workload that you simply usually would have finished with twin A76s, maxed out, is now barely tapping the fuel with twin X1s. “


The GS201 Tensor is predicted to debut with the Pixel 7 collection of telephones, which is able to embody the Pixel 7 and Pixel 7 Professional. If historical past is any indicator, we would see it additionally come to a future Pixel a-series (in all probability the Pixel 7a in 2023). Google has plans to launch a Tensor-powered pill as effectively, although it isn’t clear if that can use the GS201 or another chip, because it’s anticipated to land in 2023.

One other {hardware} codename has been tied to the GS201, however primarily based on the title itself – Ravenclaw, a portmanteau of “Raven” (Pixel 6) and “claw” for the massive cat names of the Pixel 7 collection (Cheeta and Panther) – that may be a check gadget meant to incorporate the Pixel 7 {hardware} inside a Pixel 6 physique. Google used an identical naming scheme for a Pixel 5 that had Pixel 6 internals.

Made by Google

With the GS201 reported getting into manufacturing as of June 2022, the speed of leaks relating to the upcoming chip will seemingly choose up quickly, and Google additionally has a historical past of taking cost throughout leak season to dribble out its personal function highlights. Odds are we’ll know extra very quickly. The longest we’ll have to attend, in both case, is till this fall’s anticipated Made by Google occasion when the Pixel 7 collection is predicted to launch.
