Google Pixel 6 Tensor chip — what it is and why it’s a big deal
During a Pixel 6 event livestream before today (Oct. xix), Google pulled the lid off the upcoming Pixel vi and and Pixel six Pro. Both volition stone the company's bespoke Tensor chip, which forgoes Qualcomm processors of years past.
Tensor is all about being smarter computationally. Google is aiming not to solve the difficult problems of computational photography and live translation by simply adding more horsepower, but instead is using specifically designed cores on the Tensor chip to more cleanly and efficiently compute intensive AI tasks.
Beneath is everything you need to know about Tensor in the Pixel six and Pixel half-dozen Pro.

Pixel vi Tensor: what is it?
Google Tensor is a System on Bit (SoC) designed to run Google's Car Learning (ML) models. Google claims it has designed Tensor for where ML is heading, not where information technology is today.
Google'southward Machine Learning Engine takes identify on the Tensor Processing Unit (TPU). The Pixel line has defined itself for years with its avant-garde computational photography. That's why the affordable Pixel 5a can compete with flagships like the iPhone 13 Pro in photography. Information technology's not just the megapixels that affair; the software that renders the images is also of import.
Image processing takes place on the avant-garde epitome signal processor (Isp). Google brought its key photography algorithms into the chip itself for better efficiency.
The 8-cadre CPU on the Tensor fleck has ii ARM-based high-performance cores, 2 mid cores and four high-efficiency cores. The GPU has 20 cores.
The Context Hub is an ultra depression power engine that brings machine learning for low-power tasks, like always-on display or "now playing" to run while not draining battery.
Google claims that with Tensor, it's trying to solve for heterogenous computing. Substantially, complex apps volition use multiple parts of the chip at once, and Google wants to ensure that unlike subsystems inside the chip work well together.
Google also went out of its way to fight dorsum confronting benchmarks that but measure out pinnacle speeds. It claims that speed lonely isn't a skillful indicator of real-world functioning. It seems that Google knows that benchmarks for Tensor on Pixel 6 volition not keep pace with the contest, especially with the A15 Bionic inside the iPhone thirteen, simply that Tensor volition bring new real-earth experiences that weren't before possible.
Pixel 6 Tensor: improve photography
The Pixel half-dozen has new cameras with bigger pixels that let in more light. This is all adept news, but Google wants to stress that its Tensor that brings images to life.
In the past, Google was able to leverage having just ane photographic camera on Pixel devices as its algorithms were able to analyze the elements of a photo and calibrate them to really brand images pop. Doing that same type of computational analysis is far more difficult on video.
Video is essentially a series of photos taken in succession at very fast speeds. And so a 60 frame-per-second video is actually more like 60 individual photos taken within the span of a second. Having a chip clarify each one of those photos would exist a difficult task for whatsoever CPU, especially for one as tiny as on a phone.
Google has worked on new tone mapping methods for video that tin cantankerous use those on video frames instantly. A new algorithm chosen HDRnet has been created to give video that Pixel look more efficiently. Using Tensor, Google can enable parts of HDRnet into the Internet service provider directly. This makes image processing faster and more efficient.
Google claims that HDRnet on Tensor can exist enabled on 4K 60fps video.
Other cool camera features thanks to Tensor include Magic Eraser, a feature that erases unwanted objects or people from photos. This feature uses Google's ML to do the task of what somebody would need to do on Photoshop, but in an instant. Face Unblur is another feature that removes the blur on a moving person's face. The example Google used was of a picayune daughter jumping. Google uses face tracking to find a face in a shot. Information technology then uses both the chief and ultrawide cameras to rails the subject. Google's ML uses the sharper image to superimpose information technology on the clearer picture, combining the blur of body move with a clear shot of the field of study's face up.
On the opposite cease, users tin can add together blur with Move Mode. This can add background blur to fast-moving objects past taking multiple photos and using ML. It also works when the background is stationary, but the subject is moving fast.
Pixel 6 Tensor: equitable photography with Real Tone
During the Pixel six presentation, Google made a big bargain of its new Existent Tone feature, and rightfully then.
In the early days of photography, when photos were being developed in dark rooms, photographers would reference Shirley cards, or cards of a white female model with brown hair, as the ideal style to calibrate pare tones, colors and lights. Shirley cards had been made in the 1950s, and various Shirleys take extended throughout photographic history. In the early on days, these women were considered "normal" or the base of operations standard.
This bias towards white peel has extended past counterpart photography and into modern digital photo processing as well. The problem is that photographing darker skin has then go a greater challenge as sensors have been calibrated to an older default.
Often systems or sensors would demand more light for those with darker peel to appear more clearly. But this is not necessarily an accurate representation of a person'southward peel tone. The machine white balance tuning and improve motorcar exposure help a person'southward skin tone look more natural, as opposed to washed out.
Pixel 6 Tensor: added security core
Google claimed in its presentation that Pixel half dozen is its about secure Pixel to engagement. It didn't go then far equally to say information technology was the almost secure smartphone to engagement, every bit that might prompt Apple and its legion of fans to counter with the increased security measures on iPhone thirteen. In trying to lucifer Apple tree's standard, Google is promising Pixel vi owners v years of security updates.
The Tensor Security Core is a CPU subsystem that's separate from the awarding processor. This is so that sensitive information runs through an isolated environment.
Titan M2 will be the dedicated security chip on the Pixel 6. It'll piece of work with the Tensor Security Core to protect sensitive user information. It's likewise better prepared against avant-garde attacks, such as those that come from electromagnetic analysis, voltage glitching and laser-fault injection.
Either way, Pixel vi earned a perfect score on a recent annotator evaluation. Although Google didn't specify which organization made this evaluation.
Titan M2, Tensor Security Core and Google'due south new opensource trusted execution surround gives Pixel 6 the near layers of hardware security out of any smartphone, the company claims.
Google wants to aid make security easier to understand and manage, and it's doing that with the Security Hub. Here, users tin see if their apps and passwords are proficient.
Google will besides notify users via a prompt on the superlative-right corner that lets them know if an app is turning on the photographic camera. Cameras tin be quickly turned off via a new toggle.
Google is keeping users up-to-date on app permissions via the Privacy Dashboard.
Similar Apple, Google is doubling down against apps that rail users. This might be a blight on services similar Facebook, which profit off of app tracking, but will exist welcome to users.
Unfortunately, it doesn't seem equally if Google is being as explicit with tracking permissions as Apple. Google is, afterwards all, an advertising visitor. So it might non be great if a mass number of Android users of a sudden opted to turn off cross-app tracking. Early analytics claimed that 96% of Apple users opted out of tracking.
But information technology is still possible. By going into Google Account settings, users tin reset Advertisement ID on Android. Users take to go to Settings > Privacy > Advanced > Ads > Reset advertizement ID.
A user's sensitive data runs through the individual compute core. Google claims that sensitive information never leaves a user's Pixel six device without explicit permission.
Spam calls and spam texts have been an absolute pain for billions of smartphone users around the world. Google'southward security core can at present identify phishing schemes, whether information technology be via text, electronic mail or some other link. It will inform users if something looks suspicious.
Pixel 6 Tensor: typing and translation
Speech-to-text has been both a benefit and a bane. When it works, it can make sending out a long text that much easier. Just when it doesn't piece of work, it requires the user to go back in and edit, sometimes taking longer than typing the text out past hand.
With Tensor, Google is touting natural language processing, i that tin can transcribe a person's vocalization more than smartly, fifty-fifty those with different accents or with food in their mouth. Not only can speech-to-text add together in punctuation marks, it knows that when a user mentions a specific proper name, information technology'll cross-reference it with those in a user's contact listing. Tensor is also smart enough to send a message when a user says "send" rather than typing out the word "send."
Users tin can likewise say "pizza emoji" and it'll add that emoji into the text.
Tensor can screen calls from unknown sources or robocalls. Pixel will ask potential spam callers why they're calling before a user decides to selection up.
Pixel half-dozen besides aims to make calling customer service a much easier experience. Google Assistant will aim to help users move through automated customer service systems and will even wait in line, listening to that abrasive Muzak in place of the user. Information technology volition then notify the user when a person has come up to the line.
Google easily has the best language translation software on the internet. Not only has its accuracy improved dramatically, the languages available are wide. Google claims that Tensor improves translation quality by eighteen% while using less than one-half as much ability every bit before. A user can reply to a text in i linguistic communication, and information technology will interpret it within the telephone and ship it off in some other. Translation is even bachelor for the camera to aid translate signs in other languages.
Live translation is also possible, meaning that with a Pixel 6, users can converse with another person in their own native language with the phone acting as an interpreter.
Pixel 6 Tensor: why information technology's a big bargain
With Apple's M1 and A15 Bionic, it's shown the industry that there'southward power in bespoke silicon. Instead of working with a base processor design that requires software to be designed around it, designing both the software and processor together tin lead to huge gains in efficiency.
Google, with its advanced automobile learning and computational photography, has come up to the same conclusion. While Qualcomm still makes powerful mobile chips, sometimes it's better non to chase horsepower alone and instead wait at ways to make a phone's engine lighter, more counterbalanced. In Tensor's instance, it was about getting as much efficient ciphering from the SoC as possible.
Already we're seeing Samsung doing the same thing with its Exynos chips as well, as rumors are pointing to greater advancements with adjacent year'southward Milky way S22.
If phone and computer manufactures shift towards custom silicon, that could mean major trouble for chip makers similar Intel and AMD. Already, Intel has seen a major market decline, coupled with a failure to output denser nanometer manufacturing processes and burdens caused by the Covid-19 pandemic. Losing Apple equally a major chip buyer didn't help either.
Still, this could all be proficient for the consumer. Apple tree's new chips are running circles around the competition, and that'south considering it was able to vertically integrate scrap and software evolution. Google took detect, and likely Microsoft has as well. Tensor'due south major touch on may not exist in ML translation and photography, just rather a shift in the larger CPU market equally a whole. One that will prioritize conjunctional hardware-software development above all else. Considering if there's one affair that holds true for Silicon Valley, no one visitor stays top-canis familiaris for long.
