Reviews for the Sony Vaio VGN-Z790
Source: Geekmontage
This Sony Vaio VGN-Z790 is a powerhouse. It is one of the fastest laptops that I have ever seen for its size. There are many 13” laptops such as the Dell XPS13, but it is not nearly as light as this product. All in all we are extremely pleased. This laptop definitely lived up to its name, as the executive laptop. We would have liked a better video card as this card is a little out of date now.

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.
P8800: Mid-range dual core processor with 3 MB level 3 cache and a TDP of 25 Watt.» 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.
