Only the Sapphire HD 6870 1GB GDDR5 copies the reference design. The other three cards are customized and only have memory chips situated around GPUs as a resemblance of reference layout. As a result, their power elements are easier to cool down and PCBs are more universal in terms of cooling.

All Radeon HD 6870 cards have two 6-pin supplementary power connectors, and the Sapphire HD 6850 1GB GDDR5 has one.
