 ## GCP VM module
 This module provides the functionality to ensure that you are utilizing Intel's latest generation processor in the creation of a virtual machine in GCP.
+ 
 
 ## Performance Data
+#### Intel Xeon 6 (Granite Rapids) now available on C4 VMs. Other variants are using the Intel Xeon 5th generation (Emerald Rapids)These C4 instances can power even more demanding workloads, delivering the highest frequency of any Google Compute Engine VM — up to 4.2 GHz, the most vCPU and RAM of any Intel-based comparable product, larger L3 cache size, and 1.35x higher maximum memory bandwidth.
+
+#### As of August 2025, the expanded C4 machine series with Intel Xeon 6 is available in 19 zones, with more expansion to come. Check the latest regional availability on our regions and zones page (https://cloud.google.com/compute/docs/regions-zones). Experience the leading performance, predictability, and control that C4 VMs deliver today! To learn more about C4 and its new capabilities, visit the C4 documentation. 
+
+#### Intel Xeon 6 Instance are available using the C4-standard-X-lssd or C4-highmem-X-lssd instance types. C4-standard-X and C4-highmem-X are going to be using 5th Gen Intel Xeon (Emerald Rapids)
