Core i7-7820HK Details

The Core i7-7820HK, released in 2017 as part of Intel's Kaby Lake-H family, is a mobile processor designed for high-performance laptops and workstations. Built on a 14 nm process, it features a 4-core, 8-thread design with a base clock of 2.9 GHz and a turbo frequency of up to 3.9 GHz. The processor operates within a 45 W TDP, with a downclocked 35 W mode for improved efficiency. Despite its age, the i7-7820HK remains relevant in the mobile segment due to its strong single-core performance and integrated Intel HD Graphics 630, which supports up to three displays and runs at a base frequency of 350 MHz, with a burst capability of 1.1 GHz.

In terms of memory support, the i7-7820HK accommodates LPDDR3-2133, DDR3L-1600, and DDR4-2400 memory types, with a maximum capacity of 64 GB and a memory bandwidth of 35.76 GB/s across two channels. It supports up to 16 PCIe 3.0 lanes and includes a variety of advanced features such as AVX2, AES-NI, and Intel Turbo Boost 2.0. The processor also includes Intel's Enhanced SpeedStep and Speed Shift technologies, allowing for dynamic power and performance adjustments. The integrated GPU, HD Graphics 630, features 24 execution units and provides adequate performance for light gaming and multimedia tasks.

Benchmark data from Passmark and other sources reveals that the Core i7-7820HK achieves a single-core score of 5658, placing it at #453 among 2060 processors, and a multicore score of 4857, ranking #776 of 2060. The overall score of 5338 positions it at #589 in the broader ranking. While it trails behind modern high-end desktop and mobile CPUs, it holds its own against many mid-range and even some premium processors. Notably, it outperforms several AMD Ryzen mobile chips like the Ryzen 5 2600H and Ryzen 3 7320U, while being slightly behind the Ryzen 7 4800U in multicore performance.

When compared to its peers, the i7-7820HK competes with processors such as the Core i7-4770K and Xeon E3-1275 v6, though it is outpaced by newer Intel and AMD offerings. Its performance is particularly strong in single-threaded workloads, where it ranks among the top tier of older-generation mobile CPUs. However, its multicore performance, while respectable, is limited by its 14 nm architecture and lack of modern optimizations.

As of March 2026, the Core i7-7820HK remains a viable option for users who prioritize single-core performance and integrated graphics in a mobile environment. It is well-suited for content creation, light video editing, and productivity tasks, especially in laptops where power efficiency and thermal constraints are critical. While not competitive with current flagship processors, it remains a capable performer for everyday computing and moderate workloads.
