With the Intel Xeon 6900P "Granite Rapids" processors that launched last week there are SNC3 and HEX clustering modes for these new processors. The default Sub-NUMA Clustering 3 (SNC3) mode for the three compute dies while the HEX mode is like SNC1 mode formerly for all three compute dies acting as one NUMA node. Using the flagship 128-core Intel Xeon 6980P processors, I ran some benchmarks looking at the real-world performance difference for SNC3 vs. HEX clustering modes on Granite Rapids.
