The Intel Core i9-12900H, introduced in early 2022, is a high-performance mobile CPU designed for laptops, based on Intel's Alder Lake architecture. This processor combines 6 performance cores (P-cores) using the Golden Cove architecture and 8 efficiency cores (E-cores) based on the Gracemont architecture. The P-cores are Hyper-Threading enabled, allowing for a total of 20 threads in conjunction with the E-cores. Performance cores in the i9-12900H operate within a clock speed range of 2.5 GHz to 5 GHz, while the efficiency cores have a lower frequency range of 1.8 GHz to 3.8 GHz. The efficiency cores' performance is comparable to Intel's older Skylake cores, for instance, the Core i7-6920HQ. The entire CPU can access up to 24 MB of L3 cache, facilitating improved data retrieval speeds and processing efficiency.


Unlike its counterpart, the 12900HK, the 12900H does not support an open multiplier for overclocking; however, it includes a full set of Enterprise-level vPro features for enhanced remote management capabilities. The integrated memory controller of the i9-12900H supports a variety of memory types, including DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267, allowing for flexible memory solutions based on performance needs and power efficiency. Intel's Thread Director hardware assists the operating system in optimizing thread assignment between the performance and efficiency cores, enhancing overall computational effectiveness, especially in multitasking environments. For artificial intelligence (AI) related tasks, the CPU integrates GNA 3.0 and DL Boost technologies, utilizing AVX2 instructions to boost processing capabilities. Intel Quick Sync Video, now in its 8th iteration as seen in Rocket Lake CPUs, supports a comprehensive range of codecs including MPEG-2, AVC, VC-1, JPEG, VP8, VP9, HEVC, and AV1, facilitating efficient video decoding tasks. Graphically, the i9-12900H includes an integrated GPU based on Intel's Xe architecture, featuring 96 Execution Units (EUs) that can reach up to 1.45 GHz. This integration allows for moderate gaming and multimedia processing capabilities without the need for an additional discrete graphics card.

From a power consumption perspective, the i9-12900H has a minimum assured power draw of 35W, with a typical base power consumption of 45W. Under maximum turbo conditions, recommended by Intel, the CPU can consume up to 115W. This processor is manufactured using Intel's 4th generation 10nm technology, referred to as Intel 7, which aims to optimize power efficiency relative to its performance output.
