They did not say that, they were comparing always with “top seller pc” or “pc in the same price range”, or “previous Mac model” without a direct comparison with any specific intel processor. In fact, when they mentioned benchmarks they were always mention performance gains in using Apple apps, which clearly are well optimized for AS. They sold the chip very well but also “playing at home” and with a really careful wording.
Basically, we need to wait for the benchmarks next week. I would say that the M1 will be on pair or slightly better than the current base options, which I think that is already positive taking into account other benefits (battery life on laptops)
