ATI is on a roll, having taped out its next generation GPU family called Southern Islands. ATI might call it the HD6xxx series, and it could be out before Nvidia gets its GTX4xx line of GPUs fully fleshed out and to market.
The news is straightforward enough. Southern Islands (SI) taped out recently, and is now moving through TSMC. Although the schedule is very tight, if all goes really well we could see a demo or two at Computex in just over a month. This puts SI slightly behind where Evergreen was a year ago, but not by much.
