The Intel Core i3-7130U is a dual-core processor of the Kaby-Lake architecture. It offers two CPU cores clocked at 2.7 GHz (without Turbo Boost) and integrates HyperThreading to work with up to 4 threads at once. The architectural differences are rather small compared to the Skylake generation, therefore the performance per MHz should be very similar. The SoC includes a dual channel DDR4 memory controller and Intel HD Graphics 620 graphics adapter (clocked at 300 MHz to 1,000 MHz). It is manufactured on improved 14 nm Intel process with FinFETs.
Performance
The average 7130U in our database only just matches the Core i5-4310U, a dual-core CPU of similar energy efficiency that launched in 2014, in multi-thread performance. While not as horribly slow as most N-class Intel chips, this Core i3 is unlikely to make a power user happy.
Your mileage may vary depending on how competent the cooling solution of your system is, and how high the CPU power limits are.
Power consumption
This Core i3 series chip has a default TDP, also known as the long-term power limit, of 15 W. Laptop makers are allowed to significantly reduce that value (7.5 W being the lower limit) resulting in lower clock speeds and lower performance.
Last but not the least, the i3-7130U is manufactured on one of the old 14 nm Intel processes for subpar, as of early 2023, energy efficiency.
The Intel Core i5-8350U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Kaby Lake Refresh generation and was announced in August 2017. Contrary to its direct predecessor the Core i5-7300U, which were still dual-cores, the i7-8350U is equipped with four cores but at a lower base frequency of 1.7 GHz. The Turbo Boost can go up to 3,6 GHz and therefore also offer good short term single core speeds. The GPU is now named Intel UHD Graphics 620 but otherwise identical to the Intel HD Graphics 620. The integrated memory controller supports DDR4-2400 / LPDDR3-2133 and dual channel memory.
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
According to Intel, the new quad core models are up to 40% faster than their dual core predecessors. Due to the reduced TDP and the same 14nm+ process, the long term performance and throttling behaviour will be interesting and depending on the laptop design. Therefore, the older 35 Watt quad-core models should be faster in applications that demand longer CPU loads.
Contrary 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. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.
Power Consumption
The chip is manufactured in an improved 14nm process with FinFET transistors (14nm+), the same as the 7th Gen Kaby Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.
