Google’s Tensor chip is just step one towards really nice Pixel telephones


Google’s Pixel 6 is shaping as much as be the corporate’s most formidable smartphone in years, largely because of the new, custom-designed Tensor processor, which goals to catapult Google to the forefront of the smartphone market with the ability of Google’s years of machine studying expertise. And Google wants it: regardless of the recognition of Pixels in tech circles, its telephones simply aren’t widespread sellers within the US, barely shifting the needle in comparison with juggernauts like Samsung and Apple and even smaller gamers like Oppo or Xiaomi.
Tensor is Google’s huge guess, centered on the AI-boosting TPU that guarantees to enhance photographs and movies, search, captioning, text-to-speech, and extra. It’s a tall order for any chip, a lot much less one targeted primarily on machine studying as its standout function — however whereas the Tensor SoC may not launch Google to iPhone-like heights simply but, it might be an important first step towards turning its Android also-ran right into a high contender.

The remainder of the SoC is a thriller proper now, however it looks as if Google might be utilizing third-party designs for issues just like the CPU, GPU, and modem — that means that the Pixel 6 will most likely really feel fairly much like some other Android smartphone powered by a Qualcomm or Samsung processor for many duties, as a substitute of some form of revolutionary improve on par with Apple’s A-series powered iPhones.
Google hasn’t given plenty of details about what Tensor’s precise structure goes to appear like for issues just like the CPU, GPU, modem, or different main elements of the SoC past the TPU. However primarily based on rumors and the truth that Google isn’t taking the prospect to crow about any main customization or advances its made right here, it’s seemingly the case that almost all of Tensor’s {hardware} stack might be outsourced designs. Qualcomm and Samsung already do one thing comparable — the Snapdragon 888 makes use of partially custom-made variations of Arm’s Cortex-X1, A78, and A55 designs, whereas Samsung’s Exynos 2100 makes use of Arm designs for each its CPU and GPU.
XDA notes extra particularly that the Tensor will seemingly be some mixture of Arm’s Cortex-A78, Cortex-A76, and Cortex-A55 CPU cores and Arm’s customary Mali GPU. Which implies that the distinction between Tensor and, say, a Snapdragon 888 or Exynos 2100 may not be that main for issues like general CPU or GPU efficiency. That’s a very good class to be in, particularly if Google is attempting to actually make a flagship gadget.

However as Google’s Rick Osterloh instructed The Verge, “the usual stuff folks take a look at might be very aggressive and the AI stuff might be completely differentiated.” The issues that make Tensor particular and distinctive aren’t how briskly it will probably run video games or how environment friendly its CPU and battery life is, although.
That implies that Tensor most likely additionally received’t be the magical resolution that Android followers have been hoping for: a {custom}, Google-made chip designed particularly for Android and the Pixel’s {hardware} to ship the form of efficiency and energy that Apple’s been in a position to supply on the iPhone for years utilizing an analogous technique.
Tensor is only a first-generation product
However the excellent news is that Tensor is only a first-generation product; it’s simple to level at Apple’s {custom} chips and demand that Google ought to do the identical, however it’s necessary to keep in mind that Apple’s earliest A-series iPhone chips began similarly. The A4 and A5 chips featured customary Arm designs for the CPU cores (with some optimization and enhancements on high), earlier than Apple switched to totally {custom} designs in later generations.
Google is rumored to be working with Samsung, which can each be manufacturing the chips — which is smart, on condition that it’s one of many solely two firms, together with TSMC, at present fabricating 5nm chips (a service it gives for quite a few firms, together with Qualcomm).
Samsung can be rumored to be working extra intently with Google on the precise design of the chips, too, leveraging its Exynos {hardware} and software program in a capability past merely manufacturing. We’ll have to attend till Google reveals extra about Tensor to know the extent of that partnership, however it may imply that Google will get some further assist in extra substantial {custom} chip enhancements than if it needed to reinvent the wheel from scratch.
The concept of a purpose-built machine studying chip in a Pixel cellphone isn’t a brand new concept for Google both. The corporate has put devoted in-house AI chips in its telephones earlier than, just like the Pixel Neural Core and Pixel Visible Core within the Pixel 2, PIxel 3, and Pixel 4 fashions, making the Tensor much less of a brand-new development and extra a refinement of its previous work.

Tensor’s TPU does appear to be the following step from that, presumably providing extra highly effective AI performance than both of these two earlier chips. It’s additionally extra intently built-in with the cellphone, with Google noting that it’s in a position to do issues like straight route picture information via the TPU.
These advantages could also be well worth the improvement of a {custom} SoC — once more, we’ll have to attend and see how Google really implements these AI options, and the way substantial of an enchancment they’re over a normal Android flagship. (A sentiment that, typically, applies to how closely Google is emphasizing the TPU as the foremost differentiator within the Pixel 6, one thing that seems like a tough factor to really promote prospects on.)
Because it stands now, although, the principle distinction between Tensor and a Snapdragon 888 seems to be prefer it’ll simply be some fancy neural community methods. However, very similar to with Apple’s early in-house chips, Tensor could be step one in an extended journey towards a extra bespoke Google chip. And that’s a much more thrilling idea than subtly higher machine studying demos.
