The Intel Core i9-13900HK: A High-Performance Mobile CPU for Gamers and Professionals

Core i9

The Intel Core i9-13900HK is a high-end mobile CPU for laptops based on the Raptor Lake-H series (Alder Lake architecture). It will probably be announced in early 2023 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 2.6 to 5.4 GHz (single core turbo, all-core 4.9 GHz) on the performance cluster and 1.9 to 3.9 GHz on the efficiency cluster.

Architecture and Core Configuration

The Intel Core i9-13900HK is based on the Alder Lake architecture which is a hybrid architecture that combines Golden Cove (performance-oriented) cores and Gracemont (efficiency-oriented) cores. It features 6 performance cores (P-cores) and 8 efficient cores (E-cores) for a total of 14 cores and 20 threads with support for Hyper-Threading. The P-cores feature a clock rate of 2.6 to 5.4 GHz (single core turbo, all-core 4.9 GHz) while the E-cores have a clock rate of 1.9 to 3.9 GHz.

All cores have access to 24 MB L3 cache, which is a large amount of cache and should help to improve performance in demanding workloads. As a K-variant, the CPU offers an open multiplicator, which allows for overclocking the CPU cores for even better performance.


The Intel Core i9-13900HK is one of the fastest 45W CPU for laptops, and it's well suited for demanding use cases such as gaming, content creation, and scientific calculations. The high core count and high clock speed give it an edge over the competition, and it should be able to handle even the most demanding workloads. The CPU is only bested by Raptor Lake-HX based models with more cores and improved P-cores (e.g., the i9-13980HX).


The integrated memory controller supports various memory types up to DDR5-5200, which is a significant increase from the 4800 MHz supported by the 12th gen. 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 now supports PCIe 5.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs. The integrated graphics card is based on the Xe-architecture and offers 96 EUs (Execution Units).

Power Consumption and Manufacturing Technology

The CPU is rated at 45 W base power (115 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured in a 10nm process at Intel, which is known as Intel 7 (improved over the 12th Gen).

Additional Features

The Core i9-13900HK also offers several other features to enhance performance and usability for users. One such feature is Intel's vPro technology, which provides advanced security and remote management capabilities for businesses and enterprise environments. However, it should be noted that the 13900HK only offers the "Essentials" features of vPro, as opposed to the full feature set offered by the 13900H.

Another feature of the 13900HK is its support for Thunderbolt 4, which is a high-speed interface that allows for fast data transfer and charging of external devices. This can be useful for professionals who need to transfer large amounts of data quickly, or for gamers who want to connect high-end external graphics cards.

Another feature of the 13900HK is its support for Wi-Fi 6 (802.11ax), which is the latest standard in wireless technology. This allows for faster internet speeds, improved network performance, and greater capacity for connected devices.

Finally, the 13900HK also supports Intel Optane Memory and Intel Rapid Storage Technology, which can help to improve system performance and responsiveness by caching frequently used data and applications.

Overclocking and Temperature

As a K-variant, the 13900HK allows for overclocking of the CPU cores, which can further boost performance for users who want to push the limits of their system. However, it's important to note that overclocking can increase power consumption and generate more heat, so users should be aware of the potential thermal limitations of their system.

The max temperature of the 13900HK is 100 °C, which is a common temperature limit for CPUs. However, it's important to note that high temperatures can reduce the lifespan of the CPU, so users should take steps to ensure proper cooling of their system if they plan to overclock or use demanding workloads.

Comparison to Other Models

Compared to the similar i9-12900HK, the 13900HK offers higher clock speeds. The 13900HK also offers improved memory support, with DDR5-5200 memory support compared to DDR4-4800 memory support for the 12900HK.

Compared to the i9-13900H, the 13900HK offers the added benefits of an open multiplicator, which allows for overclocking, and vPro "Essentials" features. However, the 13900H offers the full feature set of vPro.

The i9-13900HK is also the top of the line in the Raptor Lake-H series, with other models like i7-13800H, i7-13700H, i7-13620H, i5-13600H, i5-13500H, and i5-13420H offering slightly lower clock speeds and core counts.

Overall, the Intel Core i9-13900HK is a powerful and versatile CPU that offers a high level of performance for demanding use cases, and a wide range of features for both professionals and enthusiasts. With its high core count, high clock speeds, and support for advanced technologies like DDR5 memory, Thunderbolt 4, and Wi-Fi 6, the 13900HK is a powerful choice for users who want the best performance from their mobile laptops.

In conclusion, the Intel Core i9-13900HK is a powerful and versatile mobile CPU that offers a high level of performance for demanding use cases, and a wide range of features for both professionals and enthusiasts.
