A MD on Monday launched a two-chip graphics card that it hopes will give it a lead in price and performance over rival Nvidia.The ATI Radeon HD 3870 X2 combines two graphics processors on a single board, giving it nearly double the performance of the single-chip Radeon HD 3870 introduced in November 2007, according to AMD. The latest graphics card tops a Teraflop, or 1 trillion floating point operations per second, which is the *****alent of a trillion mathematical calculations per second. AMD’s latest product would compete with Nvidia’s GeForce 8800 Ultra that starts at $630. The Radeon HD 3870 X2 has a suggested retail price of $449.
