No overclocking of 1.2 GHz Mamba to 1.4 GHz needed as APM86691 and APM86692 ("Black Mamba") got announced running at up to 1.4 GHz:

So for now the PacketPro family of chips has those members:

APM86190 (Green Mamba, single-core)
APM86290 (Green Mamba, dual-core)
APM8639x (Diamondback, single-core and dual-core)
APM86491 (Catalina, single-core)
APM8669x (Black Mamba, single-core and dual-core)
APM86791 (Keelback, single-core)

I assume that there's an APM8659x still to come ;-)
