Intel's (INTC) next-gen Bay Trail (Valleyview) tablet CPU will feature four 2.1 GHz. cores and arrive in early 2014, according to leaked slides. The current Clover Trail CPU, by comparison, offers two 1.5 GHz. cores. Bay Trail will also feature an Intel HD 4000 GPU and (thanks to 22nm manufacturing) improved battery life.
