Reviews for the Sony Vaio VGN-Z11VN
Source: Reg Hardware

We like the Vaio Z11's performance, portability and connectivity, but we were disappointed with the battery life - especially because its dual-GPU set-up is supposed to improve it. If battery life doesn't matter to you, you have deep pockets and you want a full-gamut RGB screen, there's a lot of to appreciate here. But more mainstream users can find better value machines out there.

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.
P9500:
The P9500 is a fast middle class dual core CPU for laptops and basically a Core 2 Duo T9400 with only 25 Watt TDP.
