The Core i7-7820HK is part of Intel’s latest generation Kaby Lake processors sporting an improved 14nm+ manufacturing process allowing for slightly higher clock speeds and better efficiency, although the performance per clock hasn’t changed since this is practically the same microarchitecture as the one used for the previous Skylake chips.
Anyway, the Core i7-7820HK offers higher operating frequency than its Core i7-6820HK predecessor – 2.9 – 3.9 GHz (for four active cores the Turbo Boost frequency drops to 3.5 GHz or 3.7 GHz for two active cores) vs 2.7 – 3.6 GHz but keeps most of the features like Hyper-Threading, (4/8 core/thread design), 8MB LL cache, a dual-channel DDR4-2400 or DDR3L-1600 memory controller and a TDP of 45W including the iGPU. Speaking of which, the processor integrates an Intel HD Graphics 630 chip clocked at 350 – 1150 MHz.
The most noticeable feature of this processor is the unlocked multiplier for easy overclocking and usually OEMs provide the needed software for doing so. In the end, the processor’s maximum frequency can be increased depending on the notebook’s cooling system.
