AMD has announced an update for one of its ATI Radeon dual-head graphics cards, especially optimizing it for use with Apple’s Mac Pro system. The HD 3870 Mac & PC Edition has a 56-bit 512MB GDDR4 frame buffer memory and 320 stream processors, together with two DVI outputs for plugging in some large-scale Cinema HD monitors.
The card has hardware decoding of high-definition video. ATI PowerPlay is built-in, which dynamically adjusts the 775MHz core GPU speed and card voltages to suit the usage environment, and like the rest of the HD 3800 series cards AMD are promising up to twice the processing performance-per-watt compared to earlier versions.
The ATI Radeon HD 3870 Mac & PC Edition uses a PCI Express 2.0 slot and should be available in late June at Apple retailers. It’s expected to be priced at around $219.
