The cooler of the HD 4670 IceQ Turbo is the famous VGA Silencer made by Arctic Cooling.
You may combine two, three or four RV730 cards in CrossFire for increased performance or better image quality settings.
An external power connector is not needed. The card will draw all its power from the PCI-Express bus.
The GDDR3 memory chips are made by Hynix and carry the model number H5RS5223CFR-N0C. With a latency of 1.0 ns they should be good for at least 1000 MHz. These are basically the same chips as used on the high-end HD 4850 cards.
This is AMD's new RV730 graphics processor. It is made in a 55 nm process at TSMC using 514M transistors.
