Intel Core i7-7700HQ vs Intel Core i7-7820HQ

Intel Core i7-7700HQ

► remove Intel 7700HQ

The Intel Core i7-7700HQ is a fast quad-core processor for notebooks based on the Kaby Lake H architecture (7th generation Core), which was announced in January 2017 at CES. It is the successor to the Core i7-6700HQ from the Skylake generation and is manufactured in an improved 14 nm+ process, so the clocks are 200 MHz higher at the same TDP. The architecture was not changed, only the video engine got an update (see our Kaby Lake article).

The integrated graphics card is called Intel HD Graphics 630, but the architecture does not differ from the 530 GPU from the Skylake generation and only the clocks are slightly higher. 

Performance

Thanks to the 200 MHz higher clocks (5.5-7.6% depending on the Boost), the CPU performance is increased and roughly on par with the Core i7-6970HQ (2.8-3.7 GHz but with 128 MB eDRAM). The TDP can also be reduced to 35 Watts (cTDP down), but this will reduce the performance.

Power Consumption

Due to its 45-Watt TDP, the CPU will be used in bigger notebooks with at least 15 inches most of the time.

Intel Core i7-7820HQ

► remove Intel 7820HQ

The Intel Core i7-7820HQ 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.

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 i7-7820HQ 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.
