Asus W90 during OC test
Even notebooks can achieve results beyond the 20,000 limit in 3D Mark 06. That lately happened with an Asus W90 which has an Intel Core 2 Quad T9400 inside. Via overclocking the CPU gains 3952.5 MHz (416.1 MHz FSB) at 1.263 Volt. The Mobility Radeon HD4870 X2 achieves clock speeds of 600 MHz (GPU) and 1,800 MHz (memory).
Respectable results for a notebook. Particularly the cooling system seems to work efficiently.
