NVIDIA GeForce GT 635M:

Essentially a renamed GeForce GT 555M available in two or more variants with 96 or 144 shaders and 128 bit / 192 bit  DDR3 or GDDR5 memory.

Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  


3632QM: An Ivy Bridge-based quad-core processor clocked at 2.2 GHz with Turbo Boost support up to 3.2 GHz. Offers an integrated HD Graphics 4000 GPU and a dual channel DDR3 memory controller. The speciality of the i7-3632QM is the low TDP of 35 Watt compared to 45 Watt of the other Ivy Bridge quad core CPUs (e.g. 3610QM).» Further information can be found in our Comparison of Mobile Processsors.


14.0":

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.

2.5 kg:

Usually subnotebooks, ultrabooks and quite lightweight laptops with 12-16 inch display-diagonal weigh as much.


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, Medion AG, a European computer hardware manufacturer, owned the majority of the company. 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.
