Reviews for the Sony Vaio VGN-AR51M

87% Review Sony Vaio VGN-AR51M Notebook | Notebookcheck
Sony and graphics… Besides a number of fine, small notebooks with LED display and elegant carbon fiber cases, Sony also offers at least one interesting series in the fields of desktop replacement notebooks, the AR models. Though big, these are aesthetically pleasing and score points especially by their bright display. Regarding video performance, Sony forges ahead anyway for a long time.

The Sony Vaio VGN-AR51M is a good performer that can even turn its hand to gaming. You won't get much more than an hour out of the battery, but given its size and weight you're unlikely to be using it on the move much anyway. The inclusion of a Blu-ray drive is a bonus, but it's a shame the resolution support doesn't allow you to make the most of it.

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.

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.

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.

T7250: Mid-range (at the time of annoucement) dual core processor based on the Merom core. » Further information can be found in our Comparison of Mobile Processsors.


This large display size is used for laptops which are mainly intended for an use on a desk.

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.

3.9 kg:

This weight is representative for typical laptops with a 14-16 inch display-diagonal.

Sony: Sony Corporation is a multinational conglomerate corporation headquartered in Japan. Sony is one of the leading manufacturers of electronics, video, communications, video game consoles, and information technology products for the consumer and professional markets. Its name is derived from sonus, the Latin word for sound. The company was founded 1946 with another name and renamed in 1958. Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its five operating segments—electronics, games, entertainment (motion pictures and music), financial services and other. Sony is a notebook manufacturer of medium size according international market shares.

From 2014, Sony has reduced the production of Vaio laptops and finally discontinued them. Sony is still present in the smartphone and tablet market, yet not among the Top 5 manufacturers.

84.67%: This rating should be considered to be average. This is because the proportion of notebooks which have a higher rating is approximately equal to the proportion which have a lower rating.
