Yes there are advantages in performance. THW showed no advantage for those using alternate graphics capability (ie: ATI). The integrated solution from intel (which the sentia line uses) has been upgraded significantly. Not only is directx-9 based, but meets ms longhorn requirements. If you use the new up-and-coming windows on your current sentia, it will downgrade its new gfx rendering engine to be like your XP is. If you have directx-9 or better you will have a significantly enhanced OS (gui-wise). When MS starts showing the new interface be prepared to want it. Sorry current sentia users.
Lets jump to some key conclusions from toms hardware:
|the 900GMA integrated graphics core of the 915GM delivers far better 3D performance than its predecessor in the 855GME
|If you have a halfway up-to-date notebook system with the 915GM's predecessor, the 855GME, and use it mainly for office applications, you won't need to upgrade to a new system for the sake of performance. On the other hand, if you need a new system and can live with integrated graphics, a unit with 915GM is definitely the way to go. This chipset is currently the best possible compromise between performance and an acceptable price for components.
The sentia was never about gaming, but about being a quality ultraportable with great battery life. There are more features from Sonoma that the Dell reviewed by Tom's didn't utilize, such as HD audio.
I would fully expect a sonoma-based laptop in a month or two. It may even use an alternate mobile gfx solution (nvidia, ati), but I doubt it.
