Intel Core i3-8145U

The Intel Core i3-8145U is a power efficient dual-core SoC for notebooks and Ultrabooks based on the Whiskey Lake generation and will probably be announced in August 2018. Compared to the similar named Kaby Lake-R processors (e.g. Core i3-8130U), the Whiskey Lake CPUs are now produced in a further improved 14nm process (14nm++) and offer higher clock speeds. The architecture and features are the same. The i3-8145U offers e.g. high Turbo clock speeds of 3.9 GHz (versus 3.4 GHz of the i3-8130U) for a single core (3.7 GHz for 2 cores) but a slightly lower base clock of 2.1 versus 2.2 GHz. The integrated GPU is still named Intel UHD Graphics 620 and the dual-channel memory controller still supports the same RAM speeds as Kaby-Lake-R (DDR4-2400 / LPDDR3-2133). Thermal Velocity Boost is not supported (only in the Core i7-8565U).

The Whiskey Lake SoCs are used with a new PCH produced in 14nm that supports USB 3.1 Gen 2 (10 Gbps) and CNVi WiFi/BT parts.

Architecture

Intel basically uses the same micro architecture compared to Skylake and Kaby Lake, so the per-MHz performance does not differ. That means Whiskey Lake is a Kaby Lake chip manufactured in the improved 14nm++ process.

Performance

Due to the higher Turbo Boost (+12% single core), the Core i3-8145U should be faster than the old Core i3-8130U (Kaby Lake-R). The single core Turbo Boost is similar to the old high end model, the Core i7-7600U. However, the guaranteed base clock of 2.1 GHz is a lot lower (2.8 GHz for the i7-7600U) and also the 2-core Turbo is lower (3.7 versus 3.8 GHz). Therefore, the performance should be similar to the Core i7-7500U (Kaby Lake).

Graphics

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 Whiskey 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 a further improved 14nm process with FinFET transistors (14nm++), the same as the 8th Gen Coffee 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.
