Google introduces ‘Axion’ CPU, Revolutionizing Datacenters

Google, known for its innovative approach to technology, has made a significant move in the world of custom silicon. While the company has already developed its own specialized chips for AI and video transcoding, it has been slower to create its own CPUs. However, that is changing with the introduction of Google’s new in-house datacenter CPU, the Axion.

The Axion processor is based on ARM’s Neoverse V2 platform, which is currently used in other chips like nVidia’s Grace. Google plans to utilize the Axion for various workloads, including web and app servers, data analytics, microservices, and AI training. According to Google, the Axion processors offer up to 50% higher performance and up to 60% better energy efficiency compared to current-generation x86-based processors. Additionally, they claim a 30% higher performance compared to competing Arm-based CPUs for datacenters. However, Google has not disclosed the specific processors they are comparing Axion to in these metrics.

While Google has not revealed the exact specifications of the Axion CPUs, they have shared that the chips incorporate their own unique features. This includes Google’s Titanium purpose-built microcontrollers, which handle networking, security, and offload storage I/O processing to the Hyperdisk block storage service. By offloading these tasks, the majority of CPU core resources are available for actual workloads. The Axion chip also utilizes conventional dual-rank DDR5 memory modules for its memory subsystem.

Rene Haas, CEO of Arm, expressed excitement about Google’s custom silicon development. He stated that Google’s use of the Arm Neoverse V2 platform in the Axion CPU is a significant milestone that showcases the optimization of custom silicon for Google’s infrastructure. Haas also highlighted the decades of ecosystem investment and Google’s ongoing innovation and open-source software contributions that ensure an exceptional experience for customers running on Arm architecture.

Google has previously deployed Arm-based processors for its own services, such as BigTable, Spanner, BigQuery, and YouTube Ads. Now, the company is ready to offer instances based on its Armv9-based Axion CPUs to customers who can leverage software developed for Arm architectures.

About ARM:

ARM, originally known as Acorn RISC Machine, is a British semiconductor and software design company that specializes in creating energy-efficient microprocessors, system-on-chip (SoC) designs, and related technologies. Founded in 1990, ARM has become a important player in the global semiconductor industry and is widely recognized for its contributions to mobile computing, embedded systems, and Internet of Things (IoT) devices. ARM's microprocessor designs are based on the Reduced Instruction Set Computing (RISC) architecture, which prioritizes simplicity and efficiency in instruction execution. This approach has enabled ARM to produce highly efficient and power-saving processors that are used in a vast array of devices, ranging from smartphones and tablets to IoT devices, smart TVs, and more. The company does not manufacture its own chips but licenses its processor designs and intellectual property to a wide range of manufacturers, including Qualcomm, Apple, Samsung, and NVIDIA, who then integrate ARM's technology into their own SoCs. This licensing model has contributed to ARM's widespread adoption and influence across various industries.
