A Closer Look
Powercolor's cooler uses two heatpipes to transport heat away from the GPU core fast. The two heatpipes go around the fan, connected to copper fins for improved heat transfer.
The other components on the card are cooled by passive heatsinks. Given the cooler design there is plenty of airflow over them. I tried to remove the copper plates that sit on the memory but the thermal tape is so strong I was afraid I would break the memory.
The PowerColor PCS 4850 can be combined with any other HD 4850 card to form a dual, triple or quad CrossFire setup.
A single six pin power connector supplies the required juice for the card. It is required for operation.
Here you would usually expect a photo of the memory chips. Since the copper plate on them is attached so strong I didn't dare to remove it. According to PowerColor, the memory used is BGA GDDR3 from Hynix with 1.0 ns.
The RV770 graphics processor is made by TSMC Taiwan in a 55 nm process.
