Reviews for the Sony Vaio VGN-Z56GG
Source: PC Authority

The VGN-Z56GG/B outstrips the best of the netbook and ultraportable worlds for longevity, but can also switch gears and assume desktop duties with its reserves of power. With Intel's mobile Core i7 looming large, it might not be long before an even more flexible successor arrives. But right now, if your budget can stretch to it, the Z Series remains as good a laptop as we've had the pleasure of using.

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.
P9700: Very fast dual core CPU and due to the 28 Watt TDP also power efficient. Compared to other P-models, the P9700 offers the full 6MB level 2 cache.» Further information can be found in our Comparison of Mobile Processsors.
13.1": This is a common display format for subnotebooks. Netbooks, UMPC and some subnotebooks have tinier displays. Nevertheless, the majority of standard laptops has a higher format. The advantage of a small display is, that the subnotebook can be small dimensioned and can be carried easily. Further the small display needs few energy, which improves the battery runtime and in consequence the mobility. The disadvantage is that the reading of texts is a bit exhausting for the eyes, especially with high resolutions.» To find out how fine a display is, see our DPI List.
1.5 kg: This sub-notebook weighs less than the average of all notebooks and represents a medium class of weight among the sub-notebooks. 11 inch displays are normal for this class of weight.
