Clock speed of Redshift clusters

Amazon Redshift is a fully managed service and does not expose internal details like clock speed and SSD storage size.

If you could elaborate what you are trying to do with this information then maybe we can get a better understanding of what you are trying to accomplish

To understand the clock speed of Redshift clusters with multiple nodes and convert vCPU to MHz/GHz units, here is the necessary information:

Understanding Clock Speed in Amazon Redshift Amazon Redshift clusters can consist of different instance types, and each instance type has its own specifications, including the clock speed of the vCPUs. However, AWS does not explicitly list the clock speed in MHz or GHz in the standard Redshift documentation. Instead, it provides the vCPU count and instance type specifications.

Steps to Convert vCPU to MHz/GHz Identify Instance Type:

Determine the instance type of your Redshift cluster nodes (e.g., dc2.large, ra3.xlplus, etc.). Consult EC2 Instance Types:

Each Redshift instance type corresponds to an EC2 instance type. AWS typically provides detailed specifications for EC2 instances, including clock speeds. Refer to the https://aws.amazon.com/it/ec2/instance-types/Types documentation to find the clock speed information.

Clock Speed Details:

For example, dc2.large corresponds to a certain CPU model with a known clock speed. AWS generally uses Intel Xeon processors, and typical clock speeds range from 2.5 GHz to 3.1 GHz or higher, depending on the generation and specific CPU model. Conversion Formula:

To convert vCPU to MHz/GHz: 1 GHz = 1000 MHz If an instance type has a clock speed of 3.0 GHz, then in MHz, it is 3000 MHz.

suppose your Redshift cluster uses dc2.large nodes, and according to the EC2 documentation, the clock speed is 2.5 GHz.

vCPU Count: Each dc2.large instance has 2 vCPUs. Clock Speed: 2.5 GHz (or 2500 MHz). Resources for Documentation Amazon Redshift Instance Types: You can refer to the Amazon Redshift Cluster Management Guide to understand different node types and their capabilities. Amazon EC2 Instance Types: Detailed specifications, including clock speeds, can be found in the https://aws.amazon.com/it/ec2/instance-types/

Conversion Example: If your instance type's vCPU has a clock speed of 2.5 GHz, here's the conversion:

2.5 GHz = 2500 MHz
