Diamonds, Crescents and Wildcats: Intel shows off its hardware for the next generation of agentic AI workloads

Intel shows three agentic AI architectures at Hot Chips 2026: the 256-core Diamond Rapids Xeon, the Crescent Island inference GPU, and the already-shipping Wildcat Lake client SoC Diamond Rapids matches AMD's EPYC Venice on cores and bandwidth but arrives in 2027 with half the threads, while Wildcat

ServeTheHome <a href="https://www.servethehome.com/intel-diamond-rapids-the-2027-intel-xeon-at-hot-chips-2026/" target="_blank">reported that the maximum configuration uses 16-core chiplets,</a> built on Intel's 18A-P process node.</p><p>Rival chipmaker AMD also offers a 256-core trim: the EPYC 9996, built on TSMC's 2nm node, keeps hyperthreading in play, effectively doubling its thread count versus Intel's flagship.</p><p>Its Crescent Island GPU is arguably the most interesting design of the three, but the least detailed: a 350W air-cooled PCIe card built on its Xe3P GPU architecture, with 32 cores feeding 256 third-generation XMX engines and 32 MB of unified L2 cache. It surprisingly uses LPDDR5X rather than HBM, but the choice seems rationalized to offer capacity at a power and cost profile that lets Intel compete meaningfully with Nvidia and AMD.</p><p>Interestingly, the 480GB figure Intel touts in its press release isn't what it will ship; Intel-branded cards cap at 160GB, and 480GB is a ceiling available to ODM partners building their own configurations. Intel also remains mum on memory bandwidth specifics and told Chips and Cheese <a href="https://chipsandcheese.com/p/hot-chips-2026-intels-crescent-island" target="_blank">it won't disclose the figure</a>; this is crucial for many AI applications, as memory bandwidth determines decode throughput, and decode throughput essentially determines token economics.</p><p>Of the three architectures that Intel talked about, Wildcat Lake is the only one you can pick up off a shelf (as a miniPC or laptop) today; it launched as Intel's Core Series 3. Intel stated that it replaced the Foveros packaging used in Panther Lake with an organic multi-chip package, eliminating the base die and, with it, assembly cost and yield loss. Compute die area fell by 38 percent, and I/O tile area by 15 percent.</p><p>The 17 TOPS NPU available to such CPUs sits well below the 40 TOPS Microsoft requires for Copilot+ certification. The 40 TOPS Intel cites is a platform total across CPU, GPU, and NPU, which arguably can be met elsewhere, but it's a sticking point for the chipmaker's AI push, which has otherwise been concentrated on capturing enterprise and hyperscale customers.</p> </article> ]]>
