This calculator tool converts vCPUs to equivalent physical CPUs for your workload planning.
How to Use the vCPU to Physical CPU Calculator
This calculator helps you convert the number of virtual CPUs (vCPUs) to the equivalent number of physical CPUs based on the number of cores per CPU and threads per core.
Steps to Calculate:
- Enter the number of vCPUs in the “Number of vCPUs” field.
- Enter the number of cores each physical CPU has in the “Number of Cores per CPU” field.
- Enter the number of threads each core supports in the “Threads per Core” field.
- Click the “Calculate” button to see the result.
Explanation:
The calculator computes the total number of physical CPUs you need by dividing the total number of vCPUs by the number of threads each physical CPU can support. The number of threads per CPU is determined by multiplying the number of cores per CPU by the number of threads per core. The final result is rounded up to the next whole number to ensure sufficient physical CPU resources.
Example:
If you have 16 vCPUs, with each physical CPU having 4 cores and each core supporting 2 threads, the total number of threads per physical CPU is 8 (4 cores * 2 threads). Thus, you would need 2 physical CPUs (16 vCPUs / 8 threads = 2).
Limitations:
Please note that this calculator assumes uniform distribution of vCPUs across physical CPUs and does not account for other factors such as hyper-threading performance and physical CPU utilization. For more accurate planning, additional factors and real-world testing should be considered.
