The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs). 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. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2).
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. The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. Perhaps surprisingly, the Core i9's multi-thread benchmark scores are not that much higher than those of Core i7-12700H, suggesting the latter might be a much better bang for the buck overall. The average 12900H in our database proves to be an outrageously fast CPU, ripping AMD Ryzen 9 6900HX to pieces as far as multi-thread performance is concerned. Compared to the 12900HK, the 12900H does not offer the open multiplicator (for overclocking) but the full "Enterprise" set of vPro features (for remote management). The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6920HQ). The clock rate ranges from 2.5 to 5 GHz on the performance cluster and 1.8 to 3.8 GHz on the efficient cluster. The P-cores support HyperThreading leading to 20 supported threads when combined with the E-cores. 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 Intel Core i9-12900H is a high-end mobile CPU for laptops based on the Alder Lake architecture. Intel Core i9-12900H ► remove from comparison
