Intel Sapphire Rapids Performance With Google Cloud Compute Engine C3

Pon, 03/27/2023 - 17:00
Back in October Google announced their Compute Engine C3 instances in private preview that featured 4th Gen Xeon Scalable "Sapphire Rapids" processors as well as making use of Google's custom Intel Infrastructure Processing Unit (IPU). Since then, back in January, was the big Sapphire Rapids launch with the likes of the Xeon Platinum 8490H being released. Last month meanwhile Google promoted the C3 VMs to public preview state. The Sapphire Rapids C3 VMs remain in "public preview" from Google Cloud during which time there are no charges involved for the CPU costs. For those wondering about the core-for-core performance of Sapphire Rapids in Google Cloud, here are my initial benchmarks of the C3 series.
