The Intel Core i7-12800H is a premium mobile processor launched in early 2022 under the Alder Lake-H umbrella. Fabricated on Intel's 10nm process, it employs a robust hybrid architecture with 6 performance cores and 8 efficiency cores, totaling 14 cores and 20 threads. This configuration makes it exceptionally well-suited for high-end gaming laptops and thin-and-light creator machines. The CPU boasts a base clock of 2.4 GHz and a maximum turbo frequency of 4.8 GHz. It features a generous 24 MB L3 cache and supports both DDR4 and DDR5 memory architectures. With a base TDP of 45W and a maximum turbo power of 115W, it strikes a fine balance between raw throughput and mobile power constraints. Unlike the 12650H, the 12800H integrates Intel Iris Xe Graphics with 96 Execution Units, providing superior graphical capability.
The Intel Core i7-12800H leverages a 6P+8E hybrid design to deliver outstanding multi-threaded performance. Featuring Iris Xe 96EU graphics, it handles hardware video encoding and light gaming effortlessly. Reaching up to 4.
8 GHz on its P-cores, it offers an excellent balance of single-core speed and parallel processing power for demanding mobile workloads.

History
Debuted in January 2022, the Core i7-12800H quickly became the darling of the high-end laptop market. It was positioned as the optimal choice for users wanting i9-level performance without paying the flagship tax. During its release, it directly competed with AMD's Ryzen 9 6900HX, often edging out in single-core and gaming benchmarks.
The 12800H powered some of the most popular creator and gaming laptops of its generation, including the ROG Zephyrus M16 and the XPS 15. Its release marked a turning point where 14 cores became the standard for high-end mobile computing, leaving previous 4-core and 6-core designs in the dust. The chip's legacy is defined by bringing workstation-class core counts to mainstream mobile form factors, drastically reducing render times for creators and providing massive headroom for game physics and background streaming.
Improvements over Previous Generation
- 8 additional E-cores
- Higher peak boost
