PowerColor Radeon HD 4830 512 MB Review
Posted on by Thomas De Maesschalck
PowerColor's new HD 4830 features the same 640 shader pipes as the AMD reference design, but comes with a big dual-slot cooler. Also new is a native HDMI output which supports HDCP and 7.1 channel audio. Thanks to a PowerColor designed PCB the card will retail about $10 cheaper than the reference design from AMD.
