Fresh from launching the first wave of UL (a.k.a. UnLimited) family of ultraportable notebooks, Asus has struck again, this time with a 13.3" model that couples switchable discrete graphics with typical CULV hardware and portability.
The Asus UL30Vt has a 13.3" 1366x768 display, a choice of dual- or single-core Intel processors, Intel GMA X4500MHD integrated graphics, Nvidia GeForce G210M 512MB discrete graphics, room for up to 4GB of DDR3-1066 memory, up to 500GB of 5,400-RPM mechanical storage, 802.11n Wi-Fi, and a choice of four- or eight-cell batteries.
Asus quotes a maximum 12 hours of battery life for the laptop, although the listed 3.3-pound weight is with the four-cell battery (which likely doesn't have anywhere near that longevity). If short battery life doesn't bother you, then you can also use the laptop's Turbo33 feature, which Asus says "integrates both hardware and software to enhance system performance by up to 33%."
The GeForce G210M GPU probably impedes battery life, too, but it should have quite a bit more punch than the Intel GMA. According to the official spec sheet, the G210M delivers 16 stream processors, a 64-bit memory interface, 72 gigaFLOPS of number-crunching power, and DirectX 10.1 support. This looks to be a 40-nm GPU, too. (Thanks to TR reader Mason for the tip.)
