Intel's 'Lunar Lake' Benchmarks Leak
Leaked benchmarks for Intel's next-gen "Lunar Lake" Core Ultra 9 CPU show moderate performance gains of 6-8% over the previous generation. While not a major leap, the metrics provide a useful competitive reference point for consumer device performance and thermal efficiency against upcoming Apple silicon.
Intel has outsourced the fabrication of Lunar Lake's most critical components to competitor TSMC. The main compute tile, which contains the CPU cores, GPU, and NPU, is built on TSMC's N3B (3nm) process, while the platform controller tile uses the N6 node. Intel CEO Pat Gelsinger stated TSMC was chosen as it was the "right technology at that point in time." The chip's architecture introduces new "Lion Cove" Performance-cores and "Skymont" Efficiency-cores. Intel projects a 14% instructions-per-clock (IPC) uplift for the P-cores and a more significant 38-68% IPC gain for the E-cores compared to the prior Meteor Lake generation. Notably, this 4P+4E core design moves away from Hyper-Threading. A major focus is AI acceleration, with the new "NPU 4" delivering up to 48 Trillion Operations Per Second (TOPS) on its own. This meets Microsoft's 40-TOPS requirement for Copilot+ PCs. Combined with the CPU and GPU, the entire Lunar Lake platform is rated for a total of 120 AI TOPS. Lunar Lake also debuts Intel's next-generation integrated graphics, codenamed "Battlemage" (Xe2-LPG). This new GPU architecture provides up to 67 TOPS for AI tasks and promises a 50% performance improvement over the graphics in Meteor Lake. This processor is specifically designed for the ultra-low power mobile segment, targeting a thermal design power (TDP) of 8W to 30W. This contrasts with the upcoming "Arrow Lake" architecture, which is aimed at higher-performance desktops and heavier laptops with core counts up to 24. Intel is utilizing its Foveros 3D packaging technology, which allows for placing LPDDR5X memory directly on the processor package. This approach reduces latency, saves physical space on the motherboard, and lowers memory power consumption by up to 40%.
