Intel Core i5-7300HQ vs Intel Core i7-7700HQ

Intel Core i5-7300HQ

► remove from comparison

The Intel Core i5-7300HQ is a quad-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. Compared to the faster Core i7 models, the Core i5 does not support Hyper Threading and has lower clocks. The CPU cores run at 2.5 - 3.5 GHz (4 cores up to 3.1, 2 cores up to 3.3 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

The performance should be quite similar to the old Core i5-6440HQ (2.6 - 3.5 GHz, Skylake) that offers the same per-MHz performance and only 100 MHz higher core speed. The performance is therefore sufficient even for demanding tasks.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1000 MHz (i7 models up to 1100). 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.

Intel Core i7-7700HQ

► remove from comparison

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.
