About the Intel Core i7-7820HK CPU
The Intel Core i7-7820HK is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q1 2017 with a suggested retail price of $378. It is part of Intel's Core i7 lineup, which is based on the Kaby Lake-H microarchitecture. The i7-7820HK is compatible with Intel BGA 1440 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel HD Graphics 630 integrated graphics solution.
Memory and Cache
The Core i7-7820HK supports DDR4-2400, DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-7820HK has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 8 MB.
Cores and Clock Speeds
The Core i7-7820HK features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.9 GHz, and it can boost up to 3.9 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The Core i7-7820HK includes an integrated graphics solution called Intel HD Graphics 630. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card.
