ATi Radeon HD 4770:Worthy Performance
At the very outset, what makes the HD 4770 special is that is the world’s first card manufactures on a 40nm process. This means that the card runs on lesser power and is cheaper to manufacture. It is smaller than both the HD 4830 and the HD 4850. It has a silent-running fan over the core and copper pipes built into the card. The card still requirs and additional power input but heating and noise was hardly an issue. Like the ATi Radeon cards, HD 4770 also has dual DVI ports and a single Video-Out port and DirectX10.1 ready. In 3D Mark’06 the card produced a score of12,718, less than 1,00 marks below the HD 4850. In 3D Mark Vantage (High and Performance presets), the card managed 4,714 and 7,948 marks, less than 500 marks away from HD 4850. This performance was carrie forward even in the gaming benchmarks where the card either fell only slightly short from the HD 4850 or even managed to beat it (espicially in Far Cry 2). The HD 4770 is priced at $150 approx. (Rs. 8,750) and at first glance it looks strange, because it is a higher price-tag than what the HD 4850 commands. However, unless you are going to pick up the 4850, wait for two months because it is highly probable that this price will drop. And through its performance, the HD 4770 has proved that the wait will be worth it.
