Reviews for the Sony Vaio VGN-Z21ZN/X

90% Sony VAIO VGN-Z21ZN/X notebook
Source: Pocket Lint English
There’s no doubt the Sony VAIO Z-series is expensive; too expensive for the regular consumer, and for most those extra tenths in performance, features, mobility will be impossible to justify. The fact remains, however, that it’s also one of the best laptops we’ve ever seen. It offers a perfect blend of performance and mobility, proving everything a laptop should be. It allows you to take it with you everywhere you go, without making compromises over your regular desktop PC. It’s everything a laptop should be.

Comment

NVIDIA GeForce 9300M GS: Compared to the 9300M G, the GS has only 8 unified shaders but a higher clock rate. Therefore, the performance should be similar according to Nvidia. Supports 
Hybrid-SLI (GeForceBoost and HybridPower) with Nvidia 9100M G and PureVideo HD (VP3).

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.


P9500:

The P9500 is a fast middle class dual core CPU for laptops and basically a Core 2 Duo T9400 with only 25 Watt TDP.

13.1":

Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

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.

1.5 kg:

This weight is typical for big tablets, small subnotebooks, ultrabooks and convertibles with a 10-11 inch display-diagonal.
