A Closer Look
Sapphire's heatsink is a very basic piece of metal. You won't find any fancy stuff like copper or heatpipes here. It's not needed given the low heat output of the RV730 GPU.
Two, three or four cards can be combined in CrossFire to improve performance or image quality.
An additional power supply is not required for operation of the card.
The GDDR3 memory chips are made by Hynix and carry the model number H5RS5223CFA-N0C. With a latency of 1.0 ns they should be good for at least 1000 MHz.
AMD uses their new RV730 GPU on the Radeon HD 4670 and 4650. The GPU has a die size of 145 mm², is made in a 55 nm process and sports 514 million transistors.
