Reviews for the Sony Vaio VGN-Z56GG

80% Sony VAIO VGN-Z56GG/B, the best ultraportable Sony has produced to date
Source: PC Authority Archive.org version
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.

NVIDIA GeForce 9300M G: Enhanced 8400M GS chip, which is manufactured in 65nm and shows slightly better performance due to a few minor optimizations.

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.

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.
