Reviews for the Sony VAIO VGN-SZ791N

71% Sony VAIO VGN-SZ791N

The 4-pound Sony VAIO VGN-SZ791N falls somewhere between a beefy ultraportable and an all-purpose laptop.  The SZ791N's power is undeniable, but the keyboard and the mouse buttons raise questions about component quality. And considering Sony's $2500 asking price, we can't help but wish for a little more.

The VAIO VGN-SZ791N/X has a lot going for it. It delivers a top-of-the-line processor and plenty of RAM, a wealth of features, and great looks. The nearly $700 premium it costs over the similarly sized, similar-performing XPS M1330 makes the Dell system a better buy, but for the extra money, you get a more business oriented machine with hard drive protection and TPM circuitry.

When Sony kicked off its SZ series of ultraportables with the VAIO VGN-SZ170P, the company showed that it was the first to understand how important discrete graphics and an optical drive were to performance-seeking world travelers. The SZ791N becomes our new ultraportable Editors' Choice by delivering a combination of outstanding performance scores and long battery life.

Comment

NVIDIA GeForce 8400M GS: NVidia GeForce 8400M GS is the DirectX 10 capable successor of the GeForce Go 7400 for laptops and technologically a slower 8400M GT video card (because of the smaller 64 Bit memory bus).

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.

There are hardly any tablets in this display size range anymore. For subnotebooks, on the other hand, it is the standard format.

The advantage of subnotebooks is that the entire laptop can be small and therefore easily portable. The smaller display also has the advantage of requiring less power, which further improves battery life and thus mobility. The disadvantage is that reading texts is more strenuous on the eyes. High resolutions are more likely to be found in standard laptops.

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.
