Core Insights - Intel's shift to hybrid core architecture aims to enhance multi-threaded performance and optimize energy efficiency in mobile designs, with mixed results in execution [3][14] - The roadmap for Intel's P-Core development from 2026 to 2028 includes several new architectures: Lion Cove, Cougar Cove, Coyote Cove, and Griffin Cove, each focusing on performance improvements and efficiency [3][10][20] Intel P-Core Roadmap - **Lion Cove**: Supports Arrow and Lunar Lake processors, featuring an expanded core front-end and a split execution back-end, manufactured on TSMC's N3B node [5][10] - **Cougar Cove**: Set to replace Lion Cove in late 2025, focusing on efficiency improvements through node reduction, specifically for mobile platforms [6][10] - **Coyote Cove**: Expected in late 2026, it will introduce significant architectural changes with enhanced branch prediction and wider cores [8][10] - **Griffin Cove**: Anticipated as Intel's last P-core, with minor architectural changes and a focus on node reduction, scheduled for late 2027 [9][10] Performance Expectations - Lion Cove is projected to achieve an IPC improvement of 10-15% [10][20] - Nova Lake will integrate dual compute chips with up to 16 P-cores, utilizing TSMC's N2P process, expected to launch in late 2026 [10][11] Unified Core Architecture - Intel plans to release its first "Unified Core" processor, Titan Lake, in 2028, merging P-core and E-core elements for improved performance and efficiency [13][20] - The unified architecture will be based on an extended E-core design, enhancing performance/area ratio (PPA) [13][14] Architectural Features - The unified core's front-end will feature a wider design with cluster architecture, while the back-end may include more vector registers and optimized multi-level data caches [16][17][19] - SMT and AVX512 support are expected to return, with IPC improvements of 10-15% over Griffin Cove [20]
