Recently AMD introduced their new graphic Processor, ATI Radeon HD 4890 graphics card.ATI Radeon HD 4890 is one of the latest graphic processor now available and the latest addition to the company’s Radeon HD 4000 series. ATI’s new graphics card uses GDDR5 memory providing twice the data per pin of GDDR3 memory. ATI Radeon HD 4890 GPUs deliver high performance when needed and conserve power when the demand on the graphics processor is low.
With ATI Stream technology, owners of ATI Radeon HD 4800 series graphics cards can help accelerate the conversion of standard and HD video into multiple formats for use on differing consumer electronics devices.The Radeon HD 4890 is equipped with a graphics engine with a clock speed at nearly 1GHz and offers a 1.36 TeraFLOPs of processing power.It features Enhanced Anti-Aliasing & Anisotropic Filtering, CrossFireX Technology, Unified Video Decoder 2 (UVD 2), Accelerated Video Transcoding (AVT) and Upscale Beyond 1080p. The new graphic card supports the PCI Express 2.0 that will prepare you for bandwidth-hungry games and 3D applications.
AMD ATI Radeon HD 4890 uses PCI Express 2.0 x16 bus interface and has HDMI output and Integrated AMD Xilleon HDTV encoder. It supports Microsoft DirectX 10.1.
