Intel Xeon 6 Granite Rapids Memory Scaling Performance From 6 To 12 MRDIMMs

Phoronix - Tue, 02/17/2026 - 23:00
With memory pricing being as wild as it is these days and with MRDIMMs on Xeon 6 Granite Rapids offering much more memory bandwidth than conventional DDR5 RDIMMs, you may be wondering about the performance impact when not populating all twelve memory channels on the Xeon 6900 series processors. In this article are benchmarks to demonstrate the performance difference of MRDIMM-8800 memory across using six, eight, ten, and twelve MRDIMMs with a Xeon 6980P server.
