* Central thermal management – on-chip thermal sensor monitors the GPU temperature and triggers thermal actions
* PCI Express lane count switching – automatically reduces the PCIe lane count when systems goes into low power modes
* Full ASPM – PCI Express "active-state" power management lowers power consumption when the bus is not active
* Refresh rate reduction – enables lower refresh rate for longer battery life
I hope they put one of those in the new MBP's. I only think you'll never see the XT in there; probably the HD2600 or 2400XT. Probably the 2600XT will run too hot for the MBP enclosure?
