Core i7-7820HQ Details

Ranking #758 of 2060 in overall performance, the Intel Core i7-7820HQ delivers a balanced blend of single-core and multi-core capabilities that remain relevant for general productivity and light gaming even as of early 2026. With a single-core score of 5358 and a multicore score of 4817, the processor demonstrates a strong emphasis on per-thread performance, a hallmark of its Kaby Lake-H architecture. This design, originally released in 2017, places the i7-7820HQ in a competitive tier that bridges the gap between mainstream mobile CPUs and entry-level workstation processors. Its 45 W TDP, while not the most efficient by today’s standards, is well-suited for high-performance laptops where thermal headroom allows sustained performance under load.

The processor features four cores and eight threads, enabled by Intel’s Hyper-Threading technology, which allows it to handle multitasking and parallel workloads with ease. Base clocked at 2.9 GHz and capable of boosting up to 3.9 GHz on a single core, the i7-7820HQ leverages Intel’s Turbo Boost 2.0 to deliver performance where it matters most. Built on a 14 nm manufacturing process, the chip includes 8 MiB of L3 cache, 1 MiB of L2 cache, and 0.25 MiB of L1 cache, ensuring low-latency access to frequently used data. These cache hierarchies contribute to the processor’s strong single-threaded performance, which places it ahead of several modern CPUs in the single-core rankings.

Integrated graphics are provided by the Intel HD Graphics 630, featuring 24 execution units and a maximum frequency of 1.1 GHz. While not suitable for modern AAA gaming, this GPU supports up to three displays and is adequate for office work, video playback, and light creative tasks. The processor supports DDR4-2400, DDR3L-1600, and LPDDR3-2133 memory types, with a maximum capacity of 64 GiB and a memory bandwidth of 35.76 GiB/s across two channels. This memory flexibility makes it a solid choice for laptops with upgradable RAM, especially in professional or multimedia applications.

The i7-7820HQ includes a full suite of Intel technologies, including AES-NI, AVX2, and Intel VT-x, enabling encryption, virtualization, and advanced vector operations. It also supports Intel Speed Shift and Enhanced SpeedStep for dynamic power management, ensuring efficient performance under varying workloads. Despite being over eight years old, the processor remains a reliable option in older high-end laptops, particularly in systems that emphasize performance over power efficiency. While it no longer competes with today’s flagship CPUs, its well-rounded architecture and strong single-core performance make it a capable choice for users who value stability and compatibility in a mobile environment.
