Based on the 59th edition of Intel's Instruction Set Architecture (ISA) extension reference manual, which was published recently, the core architectures for its upcoming Nova Lake client processor and Diamond Rapids server processor have been made clear. Nova Lake is set to embrace a hybrid architecture that combines Coyote Cove performance cores (referred to as P-cores) with Arctic Wolf efficiency cores (known as E-cores). Meanwhile, the Diamond Rapids server processor will be outfitted with Panther Cove performance cores. Nova Lake is anticipated to make its debut in 2026, leveraging Intel's cutting-edge 18A process technology. The desktop flagship variant, the Core Ultra 9 385K, will boast an integration of 52 hybrid cores. This comprises 16 P-cores, 32 E-cores, and 4 ultra-low-power cores. Additionally, it will support DDR5-8000 memory and PCIe 5.0 expansion capabilities. Diamond Rapids is tailored for high-performance computing scenarios. It can achieve scalability of up to 256 cores through a design that eschews Simultaneous Multithreading (SMT). The processor will feature an LGA9324 socket and offer support for DDR5-7200 memory.
