The Pixel 6 and the Pixel 6 Pro are the primary devices to come with Google’s custom Tensor silicon chip as opposed to the mainstream Snapdragon 888. At the Pixel 6 release occasion, Google devoted maximum of its efforts detailing the brand new Tensor system-on-a-chip (SoC). Hailing it because the maximum powerful cellular chipset, Google said it has applied its Machine Learning (ML) information to bring onboard A.I. Competencies to a cellphone with the brand new chipset. The declare will be positioned to check finally whilst reviewers evaluate it with Qualcomm’s top class tier chipset — the Snapdragon 888 and Snapdragon 888 Plus — and Apple’s present day A15 Bionic chip.
Google Tensor vs Qualcomm Snapdragon 888, which have the best chipset?
With the Pixel 6, Google may also ultimately be prepared to tackle Apple, and a important weapon on this face-off might be its custom Tensor gadget-on-chip. But earlier than it may undertaking the large canine, first, we want to look how the Google Tensor stacks up versus the Qualcomm Snapdragon 888.
Why Tensor within the first place?
The Google Pixel 6 changed into never a well-kept secret. Ahead of the launch, there have been masses of compelling leaks and legit certifications revealing key details about the upcoming smartphones. Google even officially introduced the Tensor chip over months before the release and later teased the design of Pixel 6 and the Pixel 6 Pro at its offline keep in New York City. Therefore, Google rather used most of its time on the release occasion speakme about Tensor’s virtues.

The Pixel — as evidenced by means of its call — has been devoted to no longer most effective improving images on smartphones in the lineup but additionally commencing up APIs for different manufacturers to undertake for higher images on their devices. While the whole telephone industry has been counting on larger camera sensors and better megapixel count on their flagship smartphone digital camera, Google has usually emphasised its computational photography algorithms can outpace advancements in phrases of camera hardware during the history of the Pixel family.
But regardless of the superior software functions, Google’s hesitation to upgrade the digital camera sensors on its flagship gadgets led to a brief decline in hobby in the Pixel telephones. The tech giant is in the end making aware efforts to cope with this by means of choosing a good deal-advanced digicam hardware to supplement its first rate camera software. Nonetheless, all of those efforts would no longer be as effective as they’re with Google’s custom chipset that allows it to maximize the overall performance performance of the brand new Pixel phones.
Diving into the hardware
The Google Silicon group mentioned tidbits of the brand new Tensor SoC, such as its layout, core depend, and devoted safety functions. This goes directly to confirm some of the leaks and speculations we recognize of the Tensor chip, which became formerly addressed to via its codename, “Whitechapel.” The following paragraphs discuss its info.
Tri-cluster, eight-middle CPU with an facet
Like most other chipmakers, Google has certified IP from ARM to layout a custom mobile silicon. The Google Tensor is prepared with an 8-core CPU which includes ARM Cortex-X1 cores, Cortex-A76 cores, and 4 Cortex-A55 cores which can be based totally on a 5nm design, the organization revealed to ArsTechnica.
Based in this facts, we can see why the Google Tensor is touted to have an part over different competitor chipsets together with Samsung’s Exynos 2100 and the Snapdragon 888 or Snapdragon 888 Plus. Both of the other chipsets additionally characteristic a tri-cluster design, like Tensor, however include a unmarried ARM Cortex-X1 middle along with 3 Cortex-A78 cores and four Cortex-A55 cores.
Tensor prioritizes efficiency
Phil Carmack, a VP at Google and the overall supervisor of Google Silicon, advised ArsTechnica the enterprise’s reasoning behind choosing two of ARM’s Cortex-X1 cores in place of simply one. Carmack says the CPU will be able to divide the load between the two Cortex-X1 cores, even for moderately good sized duties, and this could make a contribution to greater efficient performance.
Carmack illustrates a use case by means of sharing a camera example. From recording to rendering, and from Google Lens detection to machine learning function, multiple tasks are happening unexpectedly when the camera is getting used. As a result, several additives of the SoC are required to work in harmony. Besides the camera hardware, the CPU, the GPU, ISP (Image Signal Processor), and the ML processing unit all integrate forces to contribute to a lag-unfastened digicam experience.
If Google have been to stick with a unmarried overall performance Cortex-X1 middle on the Tensor — as is the case with its Snapdragon and Exynos counterparts, this workload might fall back to the “medium” Cortex-A76 cores jogging at full capability but still lag. In evaluation, two Cortex-X1 cores can execute the identical workload with greater performance and lower strength intake than the medium cores. A better energy efficiency whilst performing obligations interprets to lower warmness era and a higher battery backup.

Notably, the Pixel 5 or the Pixel 4a 5G, which used the Snapdragon 765G chipset, had been plagued with extreme heating troubles, mainly at the same time as the use of the digital camera. A custom CPU structure, consequently, need to — in idea — permit the Pixel 6 and the Pixel 6 Pro to allocate assets extra optimally.
On one hand, even as Google chooses to go all-in with Cortex-X1 cores rather than one, it’s far a chunk surprising to peer Tensor the usage of as a minimum three-generations-antique medium cores. The Snapdragon 888 and the Exynos 2100 use medium cores primarily based on Cortex-A78, that is noticeably more green than the Cortex-A76 deployed on Tensor. Google, unfortunately, did now not bother to provide any sound reasoning for this.
Furthermore, for low-intensity operations like maintaining the Always-On Display (AOD) and Now Playing, the Google Tensor has a unique Context Hub. Once again, a committed unit for duties with low power intake is a step towards extra strength performance.
Google Tensor SoC makes use of a 20-center GPU and a Samsung 5G modem
Alongside the tweaked CPU design, Google Tensor turned into earlier reported to characteristic a Mali-G78 GPU — the same as the Exynos 2100. Google says this is a 20-core photographs processor, that is specially designed to supply top rate gaming overall performance. It additionally claims the GPU has 370% better performance than the one at the Pixel five. The actual-world overall performance will simplest be acknowledged once we’ve got the gadgets to run pics benchmarks and test games on them.
The Google Tensor is possibly to rely on Samsung’s Exynos 5123 modem for its 5G skills in most markets as opposed to opting for a Qualcomm modem. Cues pointing to the lifestyles of a Samsung modem at the Google Pixel 6 and the Pixel 6 Pro have been first noticed in Android 12 beta by way of XDA and later confirmed in a record by way of Reuters.
The Exynos modem helps both Sub-6GHz and mmWave 5G frequencies. But latest findings recommend that best sure service-locked versions of the Pixel 6 guide both sorts of 5G signals at the same time as the unlocked fashions guide best Sub-6GHz 5G. This method, no longer all Pixel 6 models will be created similarly but Digital Trends’ Erika Rawes says that it clearly doesn’t count number.
So, the unlocked Google Pixel 6 does NOT assist mmWave 5G. It's sub-6GHz simplest. The Verizon version (not certain approximately AT&T and T-Mo but) does include mmWave within the Pixel 6, that’s why it charges $a hundred greater than the unlocked model. #GooglePixel6Pro #GooglePixel
Google Tensor is big on protection
The Google Tensor chipset functions the second one era of its committed safety chip — the Titan M2. The Titan M2 is the successor to the first-gen Titan safety chip that has been gift at the premium Pixel smartphones for the reason that Google Pixel three. Google says the new security chip is designed to defend sensitive statistics such as passwords and PINs against online breaches as well as bodily assault strategies which include “electromagnetic evaluation, voltage glitching, or even laser fault injection.”

Alongside the Titan M2 chip, the Pixel 6 smartphones can even feature a Tensor Security Core — a CPU-based totally sub-gadget that is particularly designed to run sensitive responsibilities in isolation so other apps do have access to this data.
A.I. Is Tensor’s primary reason
Despite claims approximately its performance, Google did not construct a custom silicon to provide a better power efficiency than Qualcomm or other competitors. The predominant reason, as Google shared unapologetically, is to provide a stable and comfortable platform to execute synthetic intelligence (A.I.) and device gaining knowledge of (ML) tasks at the phone itself, with out counting on a cloud infrastructure. In fact, the chipset attracts its name from Google’s Tensor Processing Units or A.I.-expanded processors used in its records facilities.
In hindsight, Google may be dropping tips approximately a custom SoC with the aid of introducing devoted A.I.-centric chips, along with the Pixel Visual Core and the Pixel Neural Core.
Besides the optimized CPU, Google Tensor SoC additionally capabilities a committed TPU — typically known as an NPU or a neural processing unit — to perform A.I.-primarily based programs on the Pixel 6 and the Pixel 6 Pro. Because of its nature and Google’s know-how with machine studying, the Tensor is designed to run device mastering fashions on the gadgets themselves.

This superior structure allows Tensor to perform complex tasks inclusive of Automatic Speech Recognition (ASR), so one can actively translate every other language on your cellphone’s default language in apps like Messages, WhatsApp, and Recorder or maybe equipment consisting of Live Caption. Additionally, advanced speech reputation also allows Tensor to interpret pauses and punctuations in speech more appropriately and using handiest 1/2 the amount of electricity as previous Pixel telephones.
In addition to better speech processing, the Tensor brings considerable improvements to pictures. First of all, the chipset now helps computational videography — except images — the usage of Google’s HDRNet. This device-studying set of rules ensures the Pixel 6 and the Pixel 6 Pro capture the most vibrant and correct hues in each frame. Tensor additionally allows functions like Face Unblur — to repair blurred faces in transferring pix, Magic Eraser — to patch undesirable objects from photographs, and a better notion of skin tones for people of shade.
Why is Tensor crucial for Pixel?
As Google relentlessly repeated for the duration of the Pixel 6 launch event, Tensor ensures that Google’s modern day advancements in A.I. May be brought directly on its latest and upcoming mobile phones. This would be difficult to attain with a popular SoC consisting of the Snapdragon 888, specially with constrained control over Qualcomm’s chipset layout manner.
Another purpose Google chose a custom SoC with two ARM Cortex-X1 cores in place of just one is to make sure greater electricity performance and fewer warmth-related losses. Unlike preceding Google smartphones such as the Pixel 5, the brand new Pixel 6 smartphones are much less likely to heat up at the same time as running habitual obligations such as shooting 4K video. The Snapdragon 888 and Exynos 2100 have also been criticized for terrible warmth control to catch up on preliminary higher performance. However, greater amounts of heat for extended periods can result in throttling and eventually reduce performance, thereby forfeiting the principle aim of better overall performance.
One last motive at the back of Google’s choice of a custom SoC is to attract the sector’s interest toward its endeavors to reclaim its misplaced dominance within the smartphone world. The largest smartphone manufacturers inclusive of Samsung, Apple, and Huawei, already make their personal custom chipsets, at the same time as OPPO has also been operating on its custom chipset reportedly. All this makes it essential for Google to go the more mile and show its competence to stay applicable within the phone industry.
