Recent Linux kernel patch notes for Intel's upcoming 'Diamond Rapids' Xeon 7 processors reveal a significant architectural shift. According to TechPowerUp, engineers detailed that 'Diamond Rapids' (DMR) will separate its compute tile (CBB) from Integrated I/O and Memory Hub (IMH) dies. Unlike the predecessor 'Sapphire Rapids,' where components were more integrated, the new design assigns dedicated discovery tables to each CBB and IMH die.

This separation allows for distinct discovery methods: PCI for IMH PMON and MSR for CBB PMON. This architectural change suggests a more modular approach, potentially improving scalability and efficiency for data center workloads. The patches also confirm support for PCIe 6.0, signaling readiness for next-generation connectivity.

While the launch is expected later this year, Intel has reportedly streamlined the lineup by cutting 8-channel variants in favor of 16-channel SKUs, focusing on high-performance server capabilities.
