The Radeon HD 6870 and HD 6850 are two of AMD’s latest offerings. Intended for the mainstream market, each of these cards comes with a friendlier price tag compared to higher-end products. Radeon HD 6870 currently sells for around US$ 239, while its little brother, HD 6850, is being offered for around US$ 179.
Budget conscious buyers might be more interested in the lower -priced HD 6850. To increase overall value, some manufacturers have come up with customized HD 6850 cards, including Gigabyte with the GV-R685D5-1GD right here. The card is outfitted with Gigabyte’s unique, Windforce 2X HSF. Aside from that, they also use a non-reference PCB design as well.

Seen from the above table, it appears that there is no notable difference between the GV-R685D5-1GD and the standard HD 6850. Too bad Gigabyte did not apply any factory overclock, but at least this card should be able to perform as good as a standard HD 6850. Don’t lose your appetite just yet, the added value of this card lies not in its technical specification, but rather in its non-reference cooler.
