Globalfoundries more advanced than TSMC, analyst says
Nevertheless, the Dresden fab is far from being outdated. The fab will probably being able to extend immersion lithography down to 28nm and perhaps even to 22nm. "In terms of technology, they are competitive for the next seven to eight years," Johnson said.
As a result of the tough competition against market leader Intel, AMD was forced to put major efforts to develop ways and methods to improve manufacturing efficiency. GF today greatly benefits from this legacy. "They probably have the best process control capability in the industry," Johnson summed up. "TSMC better should look over its shoulder."

The analyst is kinda vague on the details but it basically reflects the sentiments of the folks within the industry when it comes to the high-performance cmos segment.
One thing not addressed by the commentary though is cost...competitive foundry offerings do not exist by technology advantage alone - it is not a "performance at any cost" environment.
A significant number of foundered IC designs simply need "good enough" process technology to function as needed in the market but if their price-point isn't below a maximum threshold then the product itself simply can't exist in the market. (no one buys $2000 GPS tom-toms, or $1000 cellphones, etc) This fact on the ground is part of the reason why ~75% of TSMC's revenue comes from IC's produced on 65nm and older process tech.
