Intel UHD Graphics 620: Integrated GPU (GT2, 24 EUs) found on some Kaby-Lake-Refresh CPU models (15 W ULV series). Technically identical to the previous Kaby-Lake GPU called HD Graphics 620. Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards. » Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
i5-10210U: Comet Lake based low power quad-core processor (technically identical to Whiskey Lake and still produced in 14nm++). The CPU cores can clock between 1.6 and 4.2 GHz (all 4 cores 3.9 GHz max.) with HyperThreading (8 threads). The integrated memory controller supports DDR4-2666 and using cTDP up/down the performance can be adjusted by the OEM (10 - 25 Watt possible, 15W default). Compared to the faster i5-10510U, the level 3 cache was reduced from 8 to 6 MB.» Further information can be found in our Comparison of Mobile Processsors.

Lenovo: Lenovo ( "Le" as in the English word legend and "novo" (Latin) for new) was founded in 1984 as a Chinese computer trading company. From 2004, the company has been the largest laptop manufacturer in China and got the fourth largest manufacturer worldwide after the acquisition of IBM's PC division in 2005. In addition to desktops and notebooks, the company also produces monitors, projectors, servers, etc.

In 2011, Lenovo acquired the majority of Medion AG, a European computer hardware manufacturer. In 2014, Lenovo took over Motorola Mobility, which gave them a boost in the smartphone market.

From 2014 to 2016 Lenovo's market share in the global notebook market was 20-21%, ranking second behind HP. However, the distance decreased gradually. In the smartphone market, Lenovo did not belong to the Top 5 global manufacturers in 2016.
