It's 1x speed. (Edit: or at least looks very like it)
Some interesting statements on Ann. BBRV puts a nice point across that 1x is good enough and that the bus doesn't really matter any more. However, somebody also says that ATI's cards only work on 2x...
Whabang, the reason Peg-1 had AGP 2x was Articia. However, bPlan dropped this chip, labelling it with the nice title "a piece of buggy crap" and went for Marvell instead. This has no AGP and so it had to be added with logic. This would be why the AGP in Peg-2 is 1x.
