Introduced in the middle of September 2008, the Radeon HD 4670 is a mainstream graphics card from ATI. Based on the latest 4000 series R700 GPU, the 4670 is based on the same 55nm fabrication process, comes with 512MB or 1GB of memory and has a 128bit memory bus. While considerably handicapped by the poor bus width, performance in the latest games remains quite high on lower resolutions. Aimed at competing with Nvidia's mainstream 9500GT offering, the 4670 outperforms it by quite a large margin, almost matching the 9600 GSO and GT in a variety of games and benchmarks, and matching the previous generation performance model from AMD, the 3850 - all while using considerably less energy and producing far less heat. Rated at a maximum 75W TDP, the 4670 does not require any additional power connections. Sadly, while the card has captured the attention of many for introducing great performance for a relatively low price, its launch has been rather lackluster, only seeing 2-3 companies release cards within the first couple weeks of launch.
