Announced at IFA 2019, Lenovo's Yoga C640 is the entry level to the company's Yoga lineup. The model that the company sent me costs $599, which isn't bad for a 13.3-inch convertible PC with pen support.

80% Lenovo Yoga C640

Overall, the Yoga C640 is a well-priced 2-in-1 convertible whose nifty features, like an integrated webcam privacy filter, are nice to have. Perhaps its signature feature is remarkable battery life, which will appeal to buyers who plan to spend a lot of time away from a power outlet.

Comment

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.


i3-10110U: Comet Lake based low power dual-core processor (technically identical to Whiskey Lake and still produced in 14nm++). The CPU cores can clock between 2.1 and 4.1 GHz (all 4 cores 3.7 GHz max.) with HyperThreading (4 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). The integrated graphics card clocks from 300 - 1000 MHz and only offers 23 instead of 24 CUs.» Further information can be found in our Comparison of Mobile Processsors.


13.3":

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

1.35 kg:

This weight is typical for big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 inch display-diagonal.


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.


80%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
