Intel Core i7-12800HX vs Intel Core i7-12800H
Intel Core i7-12800HX
► remove from comparison
The Intel Core i7-12800HX is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in mid 2022 and offers 8 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 24 supported threads when combined with the E-cores. The clock rate ranges from 2.0 to 4.8 GHz on the performance cluster and 1.5 to 3.4 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 25 MB L3 cache. The CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i7-12850HX, the 12800HX does not offer vPro or ECC memory support.
Features
The integrated memory controller supports various memory types up to DDR5-4800 and DDR4-3200. 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 supports 48 PCIe lanes consisting of 16 Gen5 (x16 or 2x8), 20 Gen4 and 12 Gen3.
The integrated graphics adapter is based on the Xe-architecture and offers 32 EUs (Execution Units) operating at up to 1.45 GHz.
Performance
The average 12800HX in our database is in the same league as the i9-12900HX while being noticeably faster than the Ryzen 7 7745HX, as far as multi-thread benchmark scores are concerned. This is a very fast chip, as of early 2023.
Your mileage may vary depending on how competent the cooling solution of your laptop is, and how high the CPU power limits are.
Power consumption
The chip's "minimum assured" power consumption sits at 45 W. Its peak Turbo power consumption is not supposed to go over 157 W and its Base power consumption is supposed to be around 55 W. Most laptop makers will probably go for a value much higher than 55 W to extract more performance out of the 12800HX.
This Core i7 series processor is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
Intel Core i7-12800H
► remove from comparisonThe 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).
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 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.
