LAPTOP Magazine has published their review of the Sony VAIO VGN-SZ791N/X, the high-end model of their 13.3″ LED-backlit series.
This model is sporting an Intel Penryn-based Core 2 Duo T9300 (2.5GHz and a full 6MB of L2 Cache).
In the graphics category, it’s one of the most unique laptops in the 13.3″ and under market – it has both a Mobile Intel X3100 intregrated graphics chipset, and an NVIDIA GeForce 8400M GS. You can literally flip a switch to change between the too (the Intel X3100 for battery life, the GeForce 8400M for graphics performance) although you do have to reboot. The NVIDIA chipset makes it a legitimate gaming ultraportable (with a carbon-fiber casing it manages to weigh in at just four pounds, even with an internal dual-layer DVD writer).
