The devices also will have the latest generation of the Titan M chip-an ultra-secure processor internally developed by Google that it first added to the Pixel in 2018. It is also unclear what technology node Tensor is based on and what made-to-order foundry is manufacturing it.
But it is unclear whether Google designed the CPU core from scratch or used ready-made blueprints from Arm. Both Apple’s and Qualcomm’s chips, which are used in hundreds of millions of smartphones globally, leverage Arm’s technology to build the central processors. The CPU is likely based on the Arm architecture.
The new processor will probably have roughly the same lineup of building blocks as the Snapdragon chip in its current-generation Pixel 5, which contains a central processing unit (CPU), graphics processing unit (GPU), image signal processor (ISP), a machine-learning engine and a range of other intellectual property (IP) blocks. Tensor is a system-on-chip (SoC) that integrates all the Pixel’s major processing components on a single die. Google is not sharing any further details about the upcoming Pixels or performance metrics of the Tensor chip. But it outlined some of the philosophy behind its new Tensor chip as part of the preview announcement. “Tensor was built for how people use their phones today and how people will use them in the future,” said Rick Osterloh, Google’s senior vice president of hardware and service, in a blog previewing its upcoming Pixel. It is generally more secure to run inferencing on a device and it also assists in reducing delays due to latency. The module could be used to run machine learning (also called inferencing) directly on the device without offloading to vast warehouses of servers in the cloud to process all the data. The chip will probably have a dedicated machine-learning module, potentially a smaller version of the TPU. The chip is a reference to the Tensor Processing Unit (TPU) used by Google in its data centers to run machine learning chores. Bringing chip development in-house could also give it more control over its future roadmap and component costs. But with its internally designed chip, the company hopes that it can more tightly integrate the software and hardware at the heart of the Pixel 6 and Pixel 6 Pro phones, reducing power and giving it a performance hike in the process. The current Pixel 5 is based on the Snapdragon 765G chipįor years, Google-developed devices put software and AI features over hardware.
The chip takes over the slot held by Qualcomm’s Snapdragon chips in every generation of Google’s Pixel, which the technology giant rolled out in 2016.
