Verdict

The Gigabyte Radeon HD 6670 2GB (GV-R667D3-2GI) is a budget-oriented graphics card featuring the 40nm 'Turks' XT GPU with 480 stream processors, a core clock of 800 MHz, and a 128-bit memory interface. This specific variant stands out by offering 2GB of DDR3 memory at an effective 1600 MHz, utilizing Gigabyte's custom-designed 100mm cooling fan and 'Ultra Durable 2' high-quality components. Its main advantages include low power consumption (66W TDP) requiring no external power connectors, a dual-link DVI-D, HDMI, and VGA output suite, and a quiet single-slot thermal design suitable for home theater or office PC upgrades. However, the use of slower DDR3 memory significantly bottlenecks performance compared to GDDR5 versions, and the card's aging architecture lacks modern driver support and the processing power required for demanding contemporary 3D gaming.
