Frequently Asked Questions

What does the Y suffix mean on Xeon Gold 6444Y?

The Y suffix indicates a high-frequency optimized variant with elevated base and turbo frequencies compared to the standard 6444 SKU making it ideal for latency-sensitive workloads.

What is the difference between Xeon Gold 6444Y and Xeon Gold 6534?

The 6444Y has 16 cores at 3.60GHz on LGA4677 (4th Gen Sapphire Rapids) while the 6534 has 8 cores at 3.9GHz on LGA4677 (5th Gen Emerald Rapids). The 6534 has higher frequency but fewer cores.

What is an S-Spec number?

An S-Spec number like SRMGQ is Intel unique identifier for a specific processor stepping used for OEM tray processors.

The Intel Xeon Gold 6444Y (SRMGQ) delivers 16 cores at 3.60GHz with 45MB L3 cache on LGA4677 — identified by S-Spec SRMGQ for OEM tray deployments requiring the highest base frequency in the Xeon Gold 6400 series for latency-sensitive enterprise workloads.
