Reviews for the Sony Vaio VPC-Z11X9E/B
Mighty Midget. A fast Core i5, gaming-suitable graphic card, DVD drive and a bright, high definition and matt display in a 1.5 kg hybrid-carbon case. That sounds good? Well, it is. But you'll have to accept a loud fan under load and a downclocked GeForce GT330M.

Comment
NVIDIA GeForce GT 330M: The Nvidia GeForce GT 330M is the successor of the GT 230M and technically just a slightly higher clocked GT 240M (but it should still maintain the power envelope of the GT 230M as the naming suggests).
Non demanding games should be playable with these graphics cards.

520M:
The Core i5-520M has only 3 MB L3 Cache (compared to the I7-640M) and clocks between 2.4-2.93 GHz (Turbo Mode). Thanks to Hyperthreading, 4 threads can be processed simultaneously. An integrated graphics card (GMA HD 3150) and a DDR3 memory controller are also included in the package.
