The Mirage 4 graphics core will again not vault it into the lead, but it will be enough to run all the flavours of Vista fast enough to get the job done. It is a DX10 part, and has all the features of it's predecessor, along with a handful of improvements. The most notable is the DRM infected Display Port and other evil rights removal mechanisms. Look for this part in early 2007, it should do what it is meant to do, at a reasonable cost.
The best thing I saw on the roadie were the power numbers. The chipsets of 2005 on a 150nm process consumed about 8W. In 2006, SiS moved to a 110nm process, and dropped that to about 5W. The next refresh will bring them to a mere 2W on an 80nm process while adding a lot of features. Not bad, and goes to show that SiS takes power very seriously. It may not have the all out horsepower of an NForce5, but at 1/20th the power, it goes to show what you can do if you set your mind to it.
