The Intel Core i9-12900HK is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 20 supported threads when combined with the E-cores. The clock rate ranges from 2.5 to 5 GHz on the performance cluster and 1.8 to 3.8 GHz on the efficiency cluster. The performance of the E-cores should be similar to old Skylake cores (compare with the Core i7-6920HQ). All cores can use up to 24 MB L3 cache. As a K-variant, the CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i9-12900H, the 12900HK only offers the "Essentials" features of vPro.
Performance
The average 12900HK in our database is in the same as the Core i9-13900H, as far as multi-thread benchmark scores are concerned. It's also almost as fast as the Ryzen 7 7745HX and the Core i5-13500HX. This is a super-fast processor, as of mid 2023; it will have no issues running any app or any game for at least two more years.
Thanks to its decent cooling solution and a long-term CPU power limit of 134 W, the Alienware x17 R2 P48E is among the fastest laptops built around the 12900HK that we know of. It can be more than 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Features
The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).
The integrated graphics card is based on the Xe-architecture and offers 96 EUs (Execution Units) operating at up to 1.45 GHz.
Power consumption
This Core i9 series chip has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The maximum Intel-recommended Turbo power consumption sits at 115 W.
The i9-12900HK is manufactured on Intel's 4th generation 10 nm process marketed as Intel 7 for lower-than-average, as of mid-2023, energy efficiency.
The Intel Core i7-12800H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 20 supported threads when combined with the E-cores. The clock rate ranges from 2.4 to 4.8 GHz on the performance cluster and 1.8 to3.7 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6920HQ). All cores can use up to 24 MB L3 cache. Compared to the 12900H, the 12800H is lower clocked and also features the full "Enterprise" set of vPro features (for remote management).

The integrated graphics adapter is based on the Xe-architecture and offers 96 EUs (Execution Units) operating at up to 1.4 GHz.
Performance
The average 12800H in our database matches the Ryzen 9 6900HS and the Core i9-11900H in multi-thread performance. Which is fairly impressive, as of mid 2022.
Thanks to its decent cooling solution and a long-term CPU power limit of 70 W, the ZBook Studio 16 G9 is among the fastest laptops built around the 12800H that we know of. It can be about 70% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Core i7 series chip has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The maximum Intel-recommended Turbo power consumption sits at 115 W.
The i7-12800H is built with Intel's fourth-gen 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
