Intel introduces Xeon 7 'Diamond Rapids' CPU lineup, built on the 18A-P process node

Intel has officially pulled back the curtain on its Xeon 7 "Diamond Rapids" server CPU lineup at Computex 2026, confirming a 2027 launch window alongside a handful of key specs. The announcement came alongside Intel's reveal of the Xeon 6+ "Clearwater Forest" chips. These two reveals give us a clearer picture of where the company's data center roadmap is headed.

Diamond Rapids is an all-P-core design, making it the natural successor to Granite Rapids in Intel's data center lineup. In terms of specs, Intel confirmed a roughly 50% increase in core count over Xeon 6, which puts the top-end configuration at around 192 cores. Memory bandwidth doubles over Granite Rapids, backed by a 16-channel configuration and support for second-generation MRDIMMs, with theoretical peak bandwidth potentially exceeding 1.2 TB/s per socket. PCIe 6.0 is also on the list.

Intel scrapped the previously planned 8-channel variant of Diamond Rapids, consolidating around the higher-bandwidth 16-channel design exclusively. The chip architecture itself uses a scalable SoC design with uniform memory latency. Intel's die shot shown at Computex revealed four CPU chiplets flanking two large I/O dies in the center, an approach structurally similar to what AMD is doing with EPYC Venice.

The 18A-P node is central to what Diamond Rapids is trying to accomplish. Intel says the process delivers about 9% better performance at the same power draw compared to standard 18A, or an 18% efficiency gain at equivalent clock speeds. Thermal resistance is also reduced by about a third, while thermal conductivity improves by 50%. For a process node revision rather than a full generational jump, those numbers are substantial and matter for Intel Foundry's ambitions to attract external customers.

One notable downside is that Hyper-Threading will not be available on Diamond Rapids. Intel has confirmed that SMT is planned for Coral Rapids, the generation that follows in 2028. Recent documentation points to Diamond Rapids using Panther Cove, an architecture not yet released. Intel's introduction of this next-gen Xeon platform was very sparse, so we should expect more details in a few months.

The 2027 launch timing is an unofficial admission of delay. Diamond Rapids was loosely expected earlier, but AMD's EPYC Venice, targeting 256 cores on Zen 6, is still on track for later this year. It looks like Intel will be playing catch-up in the server space for at least another 12 months. Coral Rapids, not Diamond Rapids, is the part Intel seems to be betting on for its long-term data center story.

Diamond Rapids is still a significant step for Intel Foundry's 18A-P node, but AMD will have a clear head start in the server space.
