I don't understand what people were expecting. There are no mystical, magical unreleased INTEL chips in that machine, so the scores are about as good as they could be with Intel. Yes, it sucks that AMD is so much ahead right now and we can't have it (like always, some thing shinier in the PC world, first Nvidia, now also AMD...) but to hell, this is still gonna be a massive upgrade for all us trashcan users!!
Apple have chosen Intel for CPUs and AMD for GPUs. It just so happens that currently, both are behind at the moment.
AMD CPUs and nVidia GPUs generally give you higher performance at this moment in time.
