The heatsink cools memory chips and voltage regulation circuitry as well as the GPU.

The card has two 6-pin PCI-Express power connectors which are specified up to 225 W power delivery.

The GDDR5 memory chips are made by Hynix, and carry the model number H5GQ2H24MFR-T2C. They are specified to run at 1250 MHz (5000 MHz GDDR5 effective).

Just like on HD 6850 and HD 6870, AMD is using a CHiL CHL8214 voltage regulator on this card. All major software utilities support this voltage controll for I2C software control and monitoring.

AMD's Barts graphics processor is made on a 40 nm process at TSMC Taiwan. It uses approximately 1.7 billion transistors on a die area of 255 mm². This is also the first GPU to carry the AMD logo instead of the ATI logo.
