Benchmarks Of Google's Axion Arm-based CPU: Competitive Performance & Compelling Value
Across a variety of workloads tested, the C4A Axion instance was delivering very nice performance and value. It was all the more impressive considering this was Google's first in-house data center processor. Those wanting to go through all of my collected benchmarks can find the data via this OpenBenchmarking.org result page().
From all the benchmarks run, the C4A Axion 48 vCPU instance was delivering 1.4x the performance of the C4 instance type powered by Intel Xeon. Or compared to prior GCE Arm instances with the T2A powered by Ampere Altra, the Axion instance at the same vCPU size was providing 1.95x the performance. Not only was the Google Axion processors delivering great performance in Google Cloud but doing so with the best performance-per-dollar too.
Besides the strong CPU performance and great value for the C4A instances with the Google Compute Engine, Axion being based on Neoverse-V2 helps ensure robust software support at introduction compared to custom core designs. The major enterprise Linux distributions on GCE can all run with the Axion-based instances today as well as having compiler support for targeting the Neoverse-V2, etc.
Thanks to Google for allowing gratis access to the Google Axion C4A instances ahead of today's general availability launch. In the coming days I will have a few more benchmarks including a look at how Google Axion competes with AWS Graviton4.
