" Are there solid links indicating that it ended up thicker than Intel's and also thicker than originally planned?"

Found it.

Interestingly, the transistor performances of Intel's Woodcrest and AMD's Barcelona appear to match fairly closely, with the Barcelona's gate leakage about half that of the Woodcrest. This is not so surprising as Intel uses a 25 percent thinner gate dielectric. AMD's device shows consistently lower gate dielectric leakage than Intel's, especially on the pFETs. The current drive for both devices is comparable, with the Barcelona coming out marginally higher for the pFET but lower for the nFET devices measured. However, the leakage current (I[subscript] off) for the nFETs was two to five times lower in the Woodcrest, suggesting the need for a bit more optimization of AMD's transistor.
