SUNNYVALE, Calif. — 9/10/2008 —AMD (NYSE: AMD) today announced the ATI RadeonTM HD 4600 серия, mainstream graphics offerings that deliver exceptional gaming and HD multimedia Производительность while consuming less Питание than a standard light bulb.² Comprising the ATI Radeon™ HD 4670 and the ATI Radeon™ HD 4650 Видеокарты, the ATI Radeon HD 4600 серия leverages the leading technology found in the award-winning ATI Radeon™ HD 4800 серия, including support for the latest DirectX® 10.1 games, superior HD multimedia capabilities and industry leading Производительность-per-watt³, all delivered at affordable prices for the mainstream graphics segment. The combined features and technologies and incredible prices makes the ATI Radeon HD 4600 серия a superb all-around performer, ideal for playing the latest games or driving a high quality home theatre entertainment experience.

The ATI Radeon HD 4670 and ATI Radeon HD 4650 Видеокарты feature AMD’s TeraScale graphics engine, with 320 stream processing cores, and are Основана на AMD’s advanced second generation 55nm process. The result is that even in today’s most demanding games like Crysis, the ATI Radeon HD 4600 серия delivers up to double the Производительность of competing products at the same price.¹ Both the ATI Radeon HD 4670 and ATI Radeon HD 4650 deliver substantial gaming horseПитание with minimal Питание draw – the ATI Radeon HD 4670 operating at under 60 watts and the ATI Radeon HD 4650 operating under 50 watts under full load – eliminating the need for additional Питание connectors and making installation a cinch. The ATI Radeon HD 4670 is immediately available with a frame buffer of 512MB GDDR3 Память with an MSRP from USD $79, while a 1GB DDR3-based variant is scheduled to ship later this month. The ATI Radeon HD 4650 features a frame buffer of 512MB GDDR2 Память and is expected to be available later in the month at an MSRP from USD $69.

“Today, AMD is providing mainstream users – one of the largest segments of the market – with superior graphics products and Производительность at previously unheard of prices,” said Rick Bergman, senior vice president and general manager, Graphics Products Group, AMD. “The success of the ATI Radeon™ HD 4000 серия validates that AMD’s shift away from the traditional means of producing large, hot, monolithic graphics chip continues to be a successful strategy AMD continues to execute against its timelines and deliver leading graphics Производительность at every price point.

“Mainstream Видеокарты – those priced under $100 – represent more than two-thirds of all desktop graphics sold today⁴,” said Dean McCarron, founder and principal, Mercury Research. Providing competitive solutions in this segment is a mandatory requirement to have a strong position in the graphics market.”

“The ATI Radeon HD 4670 proved to be an excellent performer, especially considering its low-Питание operation and affordable price,” said Marco Chiappetta, HotHardware.com. “AMD’s new ATI Radeon HD 4670 handily outperformed the ATI Radeon HD 3650 and GeForce 9500 GT across a broad range of benchmarks and just missed hitting the mark set by more expensive offerings. The ATI Radeon HD 4670 performed very well in our benchmark testing, which included a number of popular 3D applications and SD and HD video playback tests.”
