that's real good! that's a palomino core, so the 1.4s are all
palomino cores?

AMD already mentionned they would continue only with this core, i'm
amazed it's already inside the 1.4s now, this also explains why
crafty ran parallel perfect. With real tbirds you can't run parallel
at all. Already suspected something like that!
