Toshiba Qosmio X505 image
The processors, which Intel is marketing as second-generation Core chips, have better power efficiency and integrated high-definition graphics capabilities than the first generation, although they still frequently come installed alongside discrete GPUs.
One of Toshiba's revamped laptops is the Qosmio X505 (pictured), which now comes with either Intel's Core i7-2630QM or Core i5-2410M CPUs. (The new generation of Core processors can be identified by the use of four rather than three numbers in the model names.)
The 18.4-inch machine is aimed at graphics-intensive applications such as gaming, coming as it does with Nvidia's new Nvidia GeForce GTX 460M GPU with 1.5GB of DDR5 memory. The X505 is priced between from $1,299 (£838) and $1,899.
