The Sapphire Radeon 6670 (Single Slot) is a modest card: low-power, passively cooled, and marketed to consumers who may be interested in something for their HTPC or the occasional foray into some light gaming.

Let's take a closer look at the Sapphire Radeon 6670 1GB single slot card and see how it fares.
