Intel Core i7-7920HQ vs Intel Core i5-7600K

Intel Core i7-7920HQ

► remove Intel i7-7920HQ

The Intel Core i7-7920HQ is a fast quad-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the consumer series at the time of the announcement. Only the Xeon E3-1535M v6 is faster (100 - 200 MHz higher Turbo clocks). Besides four cores including Hyper-Threading support running at 3.1-4.1 GHz (4 cores up to 3.7 GHz, 2 cores up to 3.9 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 is a bit higher compared to the Skylake predecessor Core i7-6920HQ (2.9-3.8 GHz) thanks to slightly higher clocks (up to 7.9%), so it is the fastest mobile consumer processor in the beginning of 2017 (mobile Xeon E5-1535M v6 has even higher Turbo clocks). 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.

Intel Core i5-7600K

► remove Intel i5-7600K

The Intel Core i5-7600K is a fast quad-core processor for desktops based on the Kaby Lake architecture and was announced in January 2017. It is the top model of the consumer Kaby-Lake-H Core i5 series at the time of the announcement. The i5 does not support HyperThreading (4 threads only) and runs from 3.8 (base speed) up to 4.2 GHz. As a K-model, the i5-7600K offers an open multiplicator for overclocking.

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 of the i5-7600K is about 10 percent above the predecessor Core i5-6600K, thanks to clock speed increases and long hold Turbo Boost clocks. Matching clock speed, there is no speed improvement from Skylake. The old top model Core i7-4790K however is still slightly faster.

Graphics

The integrated Intel HD Graphics 630 has 24 Execution Units (similar to previous HD Graphics 530) running at 350 - 1150 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 slightly. Intel still specifies the TDP with 91 Watts, which is a lot more than the 45 Watts of the mobile Kaby-Lake-H CPUs.
