Google’s Pixel smartphones are powered by the model’s in-house system on a chip (SoC) known as Tensor G2. It is Google’s second-generation SoC and it is named after the Tensor Processing Items (TPU) that Google makes use of in its knowledge centres. This is what you have to find out about Tensor.
What’s Google Tensor?
Tensor is Google’s in-house SoC, which it makes use of to energy its Pixel telephones. Earlier than the Pixel 6 and Pixel 6 Professional, Google relied on Qualcomm processors, as do most different Android devices within the US. Globally, nonetheless, there may be extra variation, with Samsung and MediaTek additionally producing chips for fashionable Android telephones.
Have in mind Apple additionally has its personal in-house silicon, the A-Collection line of chips. That does not imply Tensor and Apple’s A-Collection are equal – Tensor is a system on a chip utilizing a mixture of elements that Google has both designed or licensed. That is maybe why Google is spending a lot time hammering residence Tensor’s synthetic intelligence and machine studying benefits, moderately than discussing specifics about CPU, GPU, and RAM.
These elements affect how briskly a telephone appears, how lengthy the battery lasts, mobile connectivity, and many others. There are additionally co-processors that deal with devoted duties equivalent to picture processing or safety. Google does have expertise in these areas: the Pixel Visible Core and Titan M chip, respectively, each have appeared in earlier telephones. And remember Google has additionally been making Tensor Processing Items for its servers for years.
Tensor even refers to Google’s open-source TensorFlow machine studying programming ecosystem. However Google Tensor marks the primary time Google has launched a cell TPU particularly for a telephone. Ideally, it permits a telephone to course of extra info on-device, moderately than ship knowledge to the cloud.
What can Google Tensor do?
Google provided press demos of what the TPU inside Tensor may do within the Pixel 6 months earlier than the primary chipset really unveiled the telephone. The Tensor G2 may be very comparable however options an improved machine studying core. Google confirmed it bettering and sharpening previous, blurry pictures in a single demo, and people pictures weren’t even taken on the Pixel 7.
The preliminary reveal of the Pixel 6 and its Tensor chip was largely targeted on the AI-enhanced TPU, and the corporate doubled down on that angle when it launched Pixel 7 in October 2022. It confirmed options like Actual Tone pictures and a Guided Body function which helps those that are blind, or with low visibility, to take a well-frame selfie by way of correct spoken prompts.
Google mentioned Tensor can deal with fast Google Assistant queries and longer audio duties like reside captions. In one other demo, Google teased an on-device auto-caption function that shortly and precisely translated language in a taking part in video from French to English in real-time. And has since proven its Recorder app having the ability to work in a number of languages, and having the ability to detect completely different audio system robotically. All are processed on the gadget securely.
Google – up to now – has additionally proven how Tensor enabled different Pixel options, equivalent to Movement Mode and extra correct face detection. There’s additionally a context hub that it powers. That is used for ultra-low-power AI duties, just like the now-playing alerts that present on the always-on show when the telephone is locked.
What are Google Tensor’s specs and benchmarks?
From a purely technical standpoint, the Tensor G2 is not all that completely different from the first-generation Tensor.
Tensor G2 packs a next-gen customized TPU (Tensor Processing Unit) for AI with a CPU cluster of two Arm Cortex-X1 cores, two mid-range (older Cortex-A78 cores), after which 4 low-power effectivity cores (Arm’s Cortex-55). Graphics are powered by an Arm GPU. Plus, there is a separate image-processing core.
It isn’t as massive a leap in machine studying efficiency because the Pixel 6 was from the Pixel 5, however it’s an enchancment nonetheless.
Along with the TPU, the Pixel 7 sports activities Google’s Titan M safety chip, to assist preserve your private knowledge safe and delicate, private requests processed on the gadget.
Is Google Tensor ARM-based silicon?
Sure. Based on Google {hardware} chief Rick Osterloh (by way of Wired), Tensor is predicated on the identical ARM structure as Qualcomm and different cell processors.
Which units supply Google Tensor and Tensor G2?
Google launched the primary Tensor-powered Pixel telephones – Pixel 6 and 6 Pro – in October 2021. These have been adopted by the extra reasonably priced Pixel 6a in 2022. All three have been powered by the first-generation Tensor chipset.
The primary units powered by the second-gen Tensor – the Tensor G2 – have been the Pixel 7 and Pixel 7 Pro, which have been launched in October 2022.
Rumours counsel that we’ll quickly be seeing the Google Pixel 7a, the Google Pixel Tablet and the Google Pixel Fold, all of that are mentioned to function Tensor SoCs. We’re anticipating to be taught extra about these units at Google’s annual developer convention, Google I/O, on Could 10 2023.
Who developed Google Tensor?
Google mentioned Tensor was co-designed alongside Google Analysis. Samsung is fabricating the chips on its 5-nanometre LPE course of.
Why did Google go its personal manner?
It has been virtually seven years since Google began making Pixel telephones, but it is nonetheless usually requested whether or not it is severe about {hardware}. Google mentioned it started work on Tensor silicon 5 years in the past (across the time it introduced it needed to purchase HTC’s phone hardware division). We suspect, with all of Google’s primary rivals gaining expertise making their very own in-house silicon, Google needed to show the Pixel line is not only a interest mission for it.
However Google has additionally talked quite a bit about how computing limitations impressed it to make Tensor. “We set about constructing a expertise platform constructed for cell that enabled us to deliver our most progressive AI and machine studying (ML) to our Pixel customers,” Google mentioned in a blog post saying Pixel 6. “We got down to make our personal System on a Chip. . . Tensor was constructed for a way individuals use their telephones right now and the way individuals will use them sooner or later”.
The corporate defined that, more and more, extra smartphone options are powered by AI and ML. Tensor won’t solely unlock computing sources for these duties, however it will possibly additionally assist present new, particular experiences for Pixel customers, whether or not it is a revamped digital camera system or speech recognition.
