Overview
- On Monday Intel said Diamond Rapids will arrive in 2027 built on the 18A‑P node and will support PCIe 6.0 to increase I/O throughput for data‑center servers.
- Intel announced a 50% core uplift versus the prior generation, which implies a top P‑core SKU of roughly 192 cores though final core counts are not yet confirmed.
- Intel has dropped an 8‑channel variant and will ship Diamond Rapids only in a 16‑channel memory configuration aimed at doubling memory bandwidth to about 1.2 TB/s with MRDIMM support potentially raising that toward 1.6 TB/s.
- Key microarchitecture and SMT (Hyper‑Threading) details remain unresolved; Intel says multithreading will return to the data‑center roadmap with Coral Rapids in 2028 and promises more technical disclosures later this year.
- Intel launched Xeon 6+ (Clearwater Forest) on 18A and rolled out related networking and GPU pieces such as Ethernet E835 and Crescent Island, but AMD’s Venice EPYC roadmap and earlier ship timing keep short‑term competition tight for cloud and AI customers.
