AMD launches teraflop graphics chip
AMD ATI Radeon HD 4800 chip first to offer one teraflop of graphics processing power
AMD has debuted the world's first teraflop graphics chip, the HD 4800 series,
The HD 4800 series has been designed to give optimized graphics performance with both high definition content and standard content, and includes support for features such as 7.1 surround sound and DirectX 10.1 as well as including energy efficiency features.
The HD 4800 chip is the first to enable cards that provide more than a teraflop of graphical computing power.
AMD released two new graphics cards using the 4800 series, the HD 4850 and the HD 4870. The HD 4850 has a core clock speed of 625MHz, 512MB GDDR3 memory and comes in a single slot PCI Express 2.0 configuration, to give one teraflop of processing power.
The dual slot HD 4870 gives even greater performance than the HD 4950, with a 750MHz core clock speed, and 512MB of GDDR5 memory, the first card to use the ultra-high bandwidth GDDR5, to give 1.2 teraflops of graphics processing.
Rick Bergman, senior vice president and general manager, Graphics Products Group, AMD said: "The ATI Radeon 4800 series represents a 2X performance jump over the ATI Radeon HD 3800 GPU, the biggest generational increase since the game-changing launch of the Radeon 9700 in 2002. AMD made a strategic decision to focus on GPU designs that maximized our efficiency and allowed us to provide enthusiasts, performance and mainstream users with the most compelling value proposition at every price point. The ATI Radeon 4800 series sets a new industry standard in key metrics such as performance-per-watt, performance-per-mm2 of chip die size, and performance-per-dollar."
