Intel Core i3-8130U vs Intel Core i5-8250U
Intel Core i3-8130U
► remove from comparison
The Intel Core i3-8130U is a power efficient dual-core SoC for notebooks and Ultrabooks (most likely) based on the Kaby Lake Refresh generation (and not Coffee Lake). It was announced in February 2018. Compared to its direct predecessor, the Core i3-7130U, the 8130U offers Turbo Boost for an increased single thread performance. 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
Clocked at 2.2 to 3.4 GHz, the Core i3-8130U offers a much better single core performance than the Core i3-7130U (2.7 GHz, no Turbo). Therefore, the overall performance should be comparable to the older Core i5-7260U (also 2.2 - 3.4 GHz). The Core i5-8250U offers four processor cores and therefore offers a much better multi-threaded performance.
Graphics
The integrated Intel UHD Graphics 620 (Intel Gen 9.5) is untouched from the 8th Gen Kaby Lake chips. In the Core i3-8130U it is rather low clocked with 1 GHz compared to the 1.1 GHz in Core i7 models. With fast dual-channel memory it can reach the performance of a dedicated GeForce 920M.
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 most likely 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. According to Intel it can be configured to 10 Watt at 800 MHz (cTDP-down).
Intel Core i5-8250U
► remove from comparison
The Intel Core i5-8250U 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 i5-7200U, which were still dual-cores, the i7-8250U is equipped with four cores but at a lower base frequency of 1.6 GHz. The Turbo Boost can go up to 3,4 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.

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 behavior 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.
