## Conclusion

TiDB Cluster Sizing Tool can help you estimate the number of cluster nodes when creating TiDB cluster for Self-Managed and TiDB Cloud Dedicated. Based on the testing conducted, we've found that the tool's estimation closely approximates the actual requirements. However, the `sysbench` results indicate better performance than the tool's estimation. This discrepancy arises because the lab uses TiDB version tidb_version, while the estimation tool is based on version v6.x.
