Hot on the heels of its latest Radeon HD 4550 and 4350 budget graphics cards, ATI debuted its mid-ranged Radeon HD4830 on Thursday. Unlike the earlier entries that hit the rock-bottom $39 price point, the new card will slide in just under the $150 level, but offer many of the same capabilities as its high-end cards.
Like the more expensive Radeon 4850 and 4870 models that share the same architecture, the 4830 uses a 55nm chip with 956 million transistors packed on board, but scales the number of stream processors down from 800 to 640. However, it still pulls off many of the same tricks, including UVD 2.0 HD video decoding, anti-aliasing, anisotropic filtering, and supports ATI’s CrossFireX for adding up to four cards to a single system.
