Comment

NVIDIA GeForce 8400M GT: NVidia GeForce 8400M GT is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8600M GS video card. Not suited for DX 10 games in high details.

Only some 3D games with very low demands are playable with these cards.

Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).

The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.

T5500:

15.40":

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.

2.8 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.

Sony: Sony Corporation is one of the largest Japanese electronics companies. The company was founded in 1946 under a different name and initially produced rice stoves. The company launched the first transistor radio. In 1958, the company was renamed Sony. Sony is a combination of the Latin word sonus (sound) and the English word sonny (little boy). Today, its core business is consumer electronics. The company is engaged in the development, design, manufacture and sale of electronic equipment, instruments, devices, game consoles and software. Sony operates in the following segments: Gaming and Network Services, Music, Images, Home Entertainment and Sound, Imaging Products and Solutions, Mobile Communications, Semiconductors, Financial Services and Others.

70%: This rating is poor. More than three quarters of the models are rated better. That is rather not a purchase recommendation. Even if verbal ratings in this area do not sound that bad ("sufficient" or "satisfactory"), they are usually euphemisms that disguise a classification as a below-average laptop.
