The company claims its ATI Radeon HD 4850 to be the world's first teraFLOPS graphics chip, with 800 stream processing cores, a stock GPU core clock speed of 625 MHz, 512 MB of GDDR3 memory rated at 2 gigabits/second. It comes in a single-slot PCI Express 2.0 configuration with a maximum board power of 110 watts, and is available with a suggested retail price of $199.
ATI Radeon HD 4870 represents 1.2 teraFLOPS of visual compute power, and features a stock GPU core clock speed of 750 MHz, 512 MB of GDDR5 memory rated at 3.6 gigabits/second. The graphic card comes in a dual-slot PCI Express 2.0 configuration with a maximum board power of 160 watts, and is available at $299.
"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," said Rick Bergman, senior vice president and general manager, graphics products group, AMD. "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."
Designed to handle the visual fidelity and clarity of all standard formats of today's high definition media, the ATI Radeon HD 4800 series includes new HD media capabilities, like picture-in-picture HD viewing, support 7.1 surround sound, and features ATI PowerPlay technology. Compared to the ATI Radeon HD 3870 series GPU, the ATI Radeon HD 4800 series delivers twice the performance while drawing only 20 per cent more power, says the company. |
