AMD Radeon HD 6730M: Due to the same codename, the 6730M should be a HD 6770M with slow DDR3 memory.

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

2540M: Fast Dual-core processor clocked from 2.6 to 3.3 GHz (Turbo Boost 2.0) based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller. » Further information can be found in our Comparison of Mobile Processsors.


15-inch display variants are the standard and are used for more than half of all laptops.

The reason for the popularity of mid-sized displays is that this size is reasonably easy on the eyes, often allows high resolutions and thus offers rich details on the screen, yet does not consume too much power and the devices can still be reasonably compact - simply the standard compromise.

2.67 kg:

With this weight, a laptop is rather heavier than average. Devices in this range shine more with screen size and performance than with mobility.

77%: This rating is not earth-shattering. This rating must actually be seen as average, since there are about as many devices with worse ratings as better ones. A purchase recommendation can only be seen with a lot of goodwill, unless it is about websites that generally rate strictly.
