ARMs Race: Ampere Altra takes on the AWS Graviton2

What this post added

This post details the evaluation of Ampere Altra processors against AWS Graviton2, both based on ARM's Neoverse N1 platform. It provides a technical comparison of their specifications, including core counts, clock speeds, cache hierarchies, and ISA extensions (ARMv8.2+ for Altra). The methodology for benchmarking using `cf_benchmark` is described, along with the results showing Ampere Altra outperforming AWS Graviton2 by 16% in single-core and 31% in multi-core performance. Specific results for OpenSSL, compression, and Golang workloads are also presented, highlighting the performance advantages of the Ampere Altra due to its higher core count and operating frequency.
