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 We would have liked a better video card as this card is a little out of date now.

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.
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.

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.
