AMD Radeon HD 7870 and HD 7850 Review

Shot of the card with the heatsink taken off – the HD 7870/7850 uses a conventional 256bit GDDR5 memory design with eight Hynix BGA modules clocked at 1.2GHz

The Pitcairn die is rotated 45 degrees and is slightly depressed below a surrounding metal shim


2 x 6 Pin PCIe power connectors HD 7870 (1 x 6 pin for the HD7850)


Only a single CrossFireX connector is present on the board, which means only up to dual cards (instead of quad) in a multi-GPU rig. The dual bios switch from the HD 69xx/79xx cards is also missing, deterring exotic modding ventures.


CHiL CHL8225G Digital PWM which can drive up to 5 phases and voltage be software controlled


Power Circuitry – 5 phases of Renasas 20658 DrMOS with Pulse PA2080 inductors


Heatsink assembly with the plastic shroud taken off


Sticky thermal pads for the rams
