Intel Core i5-8260U

Intel i5-8260U

The Intel Core i5-8260U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Coffee-Lake generation and was announced in August 2019. Compared to the predecessor, the Kaby Lake based i5-8250U, the 8260U offers a higher Turbo of 3.9 vs 3.4 GHz and is produced in the 3rd generation of 14nm (14nm++ vs 14nm+). 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.


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.


Thanks to the improved Turbo clock speed, the single core performance is improved compared to the older i5-8250U. Due to the low TDP, 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.


The integrated Intel UHD Graphics 620 (Intel Gen 9.5) is untouched from the 8th Gen Kaby Lake chips. With fast dual-channel memory it can reach the performance of a dedicated GeForce 920M.

Contrary to Skylake, Kaby Lake and Coffee 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 (3rd generation) with FinFET transistors (14nm++). Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 10 (cTDP Down) and 25 Watts.
