The Intel Core i7-7820HK is a fast quad-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It is the second fastest model of the consumer series at the time of the announcement. Only the i7-7920HQ and Xeon E3-1535M v6 are faster. Besides four cores including Hyper-Threading support running at 2.9 - 3.9 GHz (4 cores up to 3.5 GHz, 2 cores up to 3.7 GHz), the processor is also equipped with the HD Graphics 630 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It is manufactured in a 14nm process with FinFET transistors.
Compared to the Core i7-7820HQ, the 7820HK lacks business features like vPro or TXT support.
Architecture
Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Performance
Due to the higher clock speeds, the performance of the i7-7820HK is slightly faster than the old Skylake top model Core i7-6920HQ (2.9 - 3.8 GHz). The performance is sufficient even for very demanding tasks and on par with powerful desktop quad-core processors.
Graphics
The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1100 MHz. The performance depends a lot on the memory configuration; it should be comparable to a dedicated Nvidia GeForce 920M in combination with fast DDR4-2133 dual-channel memory.
Contrary to Skylake, Kaby Lake now supports hardware decoding for H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2.
Power Consumption
The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 45 Watts, but it can also be reduced to 35 Watts by the notebook manufacturers (cTDP down). This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods.
The Intel Core i3-10110Y is an extremely power efficient dual-core SoC for small laptops and tablets that was announced in August 2019. The faster models, like the Core i5-10310Y offer two additional cores however.
Performance
While we have not tested a single system built around the 10110Y as of August 2023, we have tested at least one laptop utilizing the 10100Y, an insignificantly slower chip (Amber Lake, 2 cores, 4 threads, up to 3.9 GHz.) Based on that, expect the 10110Y to be noticeably faster than the AMD 3050e. Performance of this kind is totally sufficient for basic day-to-day activities, as of late 2022.
Your mileage may vary depending on how high the CPU power limits are.
The integrated graphics adapter however is still the same as in the previous generations. It should be still called Intel UHD Graphics 615 and runs at 300 - 1000 MHz in the i3. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder.
The TDP is specified at 7 Watts but can be varied from 5.5 to 9 Watt from the manufacturer (cTDP up/down) resulting in different performance (especially Turbo durations). Interestingly, the faster Core i5-10210Y with two more cores can be configured to lower 4.5 Watt.
