Some very nice people have sent us the important part of the RV670 driver and it confirms that the RV670XT will be branded as Radeon HD 3870, while the RV670PRO will be branded as Radeon HD 3850.
We were shocked to see that in the device ID, the ATI driver recognizes this new chipet as RV630, but we are confident that the chipset is brand new. The device name is completely different and this tells the driver that it should install the drivers for RV670, not the RV630.
Enough said; here is the picture.
