A Closer Look
Powercolor's cooler uses a design that connects a copper core to a large number of cooling fins via heatipe. As mentioned before, this design has been in service for several years and is thus well tested and mature.
Operation of the card requires one six-pin PCI-E power connector. Power consumption is low, but in the worst case slightly higher than 75W which would be allowed without power connector.
The GDDR5 memory chips are made by Hynix, and carry the model number H5GQ1H24AFR-T2C. They are specified to run at 1250 MHz (5000 MHz GDDR5 effective).
The GPU voltage is managed by a uP6201BQ voltage controller (same as on many HD 4770 designs).
This is AMD's new Juniper GPU, it comes with 1040 million transistors, and is produced on a 40 nm process at TSMC Taiwan.
