1.1 Nehalem microarchitecture (1st generation).

This will obviously affect the performance, because the Turbo Boost cannot be maintained for longer periods. Intel still specifies the TDP with 15 Watts, but it can also be reduced to 7.5 Watts by the notebook manufacturers (cTDP down). The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. The dual-core Kaby Lake processors, which were announced in January, should also support HDCP 2.2. The performance depends a lot on the memory configuration it should be comparable to a dedicated Nvidia GeForce 920MВ in combination with fast DDR4-2133 dual-channel memory.Д¬ontrary 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 integrated Intel HD Graphics 620 has 24 Execution Units (similar to previous HD Graphics 520) running at 300 - 1150 MHz. The performance is sufficient for demanding tasks (except some games that may need four real cores). That means, the i7-7600U is (at the time of announcement in beginning of 2017) the fastest dual core processor for laptops. With 2.5 to 3.9 GHz, the Core i7-7600U clocks significantly higher than the old Core i7-6500U (2.5 - 3.1). It is manufactured in a 14nm process with FinFET transistors. Besides two cores, the processor is also equipped with the HD Graphics 620 GPU as well as a dual-channel memory controller (DDR3L-1600/DDR4-2400). It integrates 2 CPU cores with Hyper-Threading support clocked at 2.8 - 3.9 GHz (2 core Turbo also 3.9 GHz). The Intel Core i7-7600UВ is a fast dual-core processor for notebooks based on the Kaby Lake architecture and was announced in January 2017. Intel Core i7-7600U в–є remove from comparison

The TDP is pretty high compared to the common 15-Watt TDP for dual-core processors, but allows a better utilization of CPU and GPU Turbo. Intel specifies the TDP with 28 Watts, which can be reduced to 23 Watts (cTDP Down) depending on the usage scenario. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.

However, there aren't any significant improvements compared to the old Iris Pro 550, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.Д¬ontrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. It has 48 Execution Units running at 300-1050 MHz and the performance is comparable to a GeForce 920MX thanks to fast eDRAM cache.

The integrated Intel Iris Plus 650 Graphics is the GT3e model of the Kaby Lake GPU (Intel Gen. Some games might still require a real quad-core processor and therefore nit run perfectly on the dual-core processor, despite Hyper Threading. This means the i5 is still one of the faster dual-core processors and should be sufficient for most scenarios. The performance of the 28-Watt CPU should be on par with the Core i7-7500U (2.7-3.5 GHz, no eDRAM, 15 Watts), but it should be a bit slower on practice due to the missing level 4 eDRAM and the lower TDP. 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. Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The chip is still manufactured in a 14nm process with FinFET transistors. It is also equipped with an Intel Iris Plus Graphics 650 GPU with 64 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The processor can execute up to four threads simultaneously thanks to Hyper Threading. The CPU has two processor cores clocked at 3.1-3.5 GHz (two cores also up to 3.5 GHz). The Intel Core i5-7267UВ is a fast dual-core SoC for notebooks based on the Kaby Lake architecture and was announced in January 2017. Intel Core i5-7267U в–є remove from comparison
