It wasn't long ago that we looked at Sony's gorgeous, if pricey, VGN-Z11WN/B ultraportable, but now we've sneaked an exclusive first glance at its forthcoming replacement. The VGN-Z21MN/B is, to all intents and purposes, the big brother of Sony's 11.1in VGN-TT11WN/B. The 314 x 210 x 33mm dimensions conceal a generous 13.1in display and belie a headline grabbing weight of just 1.43kg.  Sony's 13.1in Z-series redefines the ultraportable template, and justifies every single penny of its sizable price tag.

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.

P8600:

Fast but still not overpriced dual core CPU. For most games and multimedia applications sufficient and due to the 25W TDP even for smaller notebooks useable.
