Again, Cloud SQL, specific CPU SKU information (such as exact processor generation and clock speed) is not directly accessible to users. Google Cloud’s approach with Cloud SQL prioritizes abstracting away the underlying hardware details to provide a managed database service.
While not directly stated, the machine type you choose (e.g., db-n1-standard-4) can give you a general idea of the underlying hardware generation. You can cross-reference this with Compute Engine’s documentation to infer the possible processor families.
Running benchmark tests on your Cloud SQL instance and comparing the results with publicly available benchmarks for different processors might give you some clues, but it’s not a guaranteed way to identify the exact SKU.
If you absolutely need to know the exact CPU SKU information, reach out to Google Cloud support and explain your specific requirements. They might be able to provide you with more details about the underlying hardware, especially if you have compliance or performance-related concerns.
