Intel Core i5-12500H vs Intel Core Ultra 9 285H vs Intel Core i9-12900H
Intel Core i5-12500H
► remove from comparison
The Intel Core i5-12500H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 4 of the 6 performance cores (P-cores, Golden Cove architecture) and all 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 16 supported threads when combined with the E-cores. The clock rate ranges from 2.5 to 4.5 GHz on the performance cluster and 1.8 to 3.3 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compared to the Core i7-6700HQ). All cores can use up to 18 MB L3 cache. Compared to the 12600H, the 12500H offers base clock for both clusters, a slower clocked iGPU and only "Essentials" vPro support.
Performance
The average 12500H in our database is in the same league as the Ryzen 9 6900HS, Ryzen 9 6900HX, Core i7-12650H and also the Core i9-11900H, as far as multi-thread benchmark scores are concerned. For something that's supposedly a mid-range chip, this kind of performance is just outrageously good, as of Q3 2023.
Thanks to its decent cooling solution and a long-term CPU power limit of 80 W, the Gigabyte G7 KE is among the fastest laptops built around the 12500H 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.
Architecture
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 80 of the 96 EUs (Execution Units) operating at up to 1.3 GHz.
Power consumption
This Core i5 has a "minimum assured" power consumption of 35 W. Its Base power consumption sits at 45 W and its maximum Intel-recommended Turbo power consumption isn't supposed to exceed 95 W. A high-performance cooling solution is a must for a CPU like this one here.
Last but not he least, Intel Core i5-12500H is manufactured on Intel's fourth-generation 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency.
Intel Core Ultra 9 285H
► remove from comparison
The Intel Core Ultra 9 285H is a mobile high-end CPU for larger notebooks based on the Arrow Lake architecture. It offers 16 cores consisting of 6 fast performance cores (Lion Cove) with up to 5.4 GHz and 8 smaller efficiency cores (Skymont) with up to 4.5 GHz clock speed and two additional low power cores with up to 2.5 GHz (Skymont). The CPU has access to 24 MB of cache and is specified with a TDP of 45 watts.
The SoC integrates a small dedicated NPU called AI Boost with 13 TOPS (Int8) and optionally supports vPro Enterprise. The integrated memory controller supports up to 192 GB LPDDR5/x-8400 or DDR5-6400 (dual channel). The integrated GPU (iGPU) is an Intel Arc 140T graphics card that offers eight Xe cores with up to 2.35 GHz.
Performance - High End
The top model offers all the cores that are built into the chip and clocks relatively high at up to 5.4 GHz. Thanks to the improved IPC of the cores (especially the efficiency cores), the CPU should reach the level of the old Raptor Lake Core Core 9 270H (6 + 8 cores, max 5.8 / 4.1 GHz). This makes the CPU ideal for very demanding tasks such as high-end gaming and content creation.
Chiplet Design
Like the desktop and HX chips, the Arrow Lake-H chips are based on individual chiplets that are placed on a 22nm base tile from Intel using Foveros 3D packaging. The CPU part comes from TSMC using the modern N3B (3nm) process. As with HX, the GPU also is produced at TSMC and is manufactured using the N5P process. SoC and I/O Tile are also from TSMC but in the older N6 process.
Intel Core i9-12900H
► remove from comparison
The Intel Core i9-12900H 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 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 12900HK, the 12900H does not offer the open multiplicator (for overclocking) but the full "Enterprise" set of vPro features (for remote management).
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.
Performance
The average 12900H in our database proves to be an outrageously fast CPU, ripping the Ryzen 9 6900HX to pieces as far as multi-thread benchmark scores are concerned. Perhaps surprisingly, the i9's multi-thread performance is not much higher than that of the Core i7-12700H, suggesting the latter might be a better bang for the buck.
With its decent cooling solution and a long-term Power Limit of 110 W, the Asus StudioBook 16 H7600ZW is one of the fastest laptops built around the i9-12900H that we know of. It can be more than 80% faster than the slowest system featuring the same chip in our database, depending on the circumstances.
Power consumption
The Core i9 has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The CPU's maximum Intel-recommended Turbo power consumption sits at 115 W.
The i9-12900H is built with Intel's 4th generation 10 nm process marketed as Intel 7 for lower than average, as of mid 2023, energy efficiency.
