AMD version is called "PowerExpress" or "
Bus
Alive
Chip
Off" (aka Baco(n)). (homage to powerNow!)
Also "Lucid Virtu" supposedly have ones that work reguardless of which vender it is.

You ll probably see
Llano Fusion APUs in laptops with
this tech (Baco),
and Hybrid Crossfire, with a discrete GPU like a 6570? or so, go for cheap and have really good batterylife.
Also AMDs version works with BOTH AMD cpus + Intel cpu IGP's.
(nvidia Optimus doesnt work with AMD CPU's probably because nvidia doesnt want it too)
While allowing for Hybrid Crossfire as well at the same time.
Even if not producers (ei apple) choose not to support it, you can "force" it on via drivers (i get from reading a artical). Apperntly any Radeon 6000m series + Sandy Bridge / AMD fusion processor, should be caple of it.
Apperntly its something new in the drivers, so you ll need cat11.4 or newer.
