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

AMD Radeon HD 7650M: Based on the same chip as the Radeon HD 6650M but with slower core clock. 480 Shader and 128 bit DDR3 interface.

Intel Core i5:

2450M: Dual-core processor based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller. The CPU is clocked at 2.5 GHz (Turbo Boost 2.8-3.1 GHz) and the GPU at 650 (1300 MHz Turbo).

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).

15.6: 15 inch display-variants are the standard and are used for more than the half of all notebooks. 15.4 inch display with 16:10 are the standard for notebook displays. However nowadays, more and more 16:9 displays with 15.6 inch appear. The reason why so many people like displays with medium size is, that this size is not exhausting for the eyes, does not need too much energy and the laptops can be kept quite compact.

2.5 kg:

This notebook is lighter than the average of all notebooks. It is too heavy for sub-notebooks. 14 inch displays are normal for this class of weight.
