AMD ha annunciato la scheda grafica ATI Radeon HD 4890, nuova soluzione flag-ship tra le sue video card a gpu singola, mostrata nelle foto seguenti, scattate dallo stesso produttore. Il chip-maker esalta le potenzialtà della scheda, che va ad integrare sia la gamma ATI Radeon HD 4800 che la stessa piattaforma Dragon, citandone una capacità di calcolo pari a circa 1.36 TeraFLOP e l'equipaggiamento con la memoria G-DDR5, operante ad una frequenza di clock prossima al GHz (975MHz).

In accordo ad AMD, la ATI Radeon HD 4890, la cui gpu è costruita con un processo di fabbricazione a 55nm ed integra quasi 1 miliardo (956 milioni) di transistor, è stata progettata per rispondere molto bene all'overclock dell'utente, il quale può conseguire in questo modo un ulteriore boost prestazionale, fermo restando che anche alle frequenze di default questo prodotto vuole essere al top di gamma dal punto di vista del rapporto prezzo/prestazioni.

Microsoft DirectX 10.1, ATI CrossFireX, ATI Stream e Unified Video Decoder di seconda generazione (UVD 2.0) sono alcune delle tecnologie supportate da questo controller che è già parte, o lo sarà a breve, dei cataloghi dei principali board maker e partner di AMD, ovvero ASUS, Club 3D, Diamond Multimedia, Force3D, GECUBE, GIGABYTE, HIS (Hightech Information Systems), Jetway, MSI, Palit Multimedia, PowerColor, SAPPHIRE Technology, VisionTek e XFX.

L'MSRP della ATI Radeon HD 4890 è pari a $249.

AMD today introduced the ATI Radeon HD 4890 graphics card, driven by the world’s most powerful graphics processor. The newest addition to the award-winning ATI Radeon HD 4000 series boasts a whopping 1.36 TeraFLOPs of compute power, superior GDDR5 memory, and super-high engine clock speeds capable of nearly 1GHz. The advanced design of the ATI Radeon HD 4890 delivers the best game experience in its class, including the latest ground-breaking DirectX 10.1 titles. In addition, with the introduction of the ATI Radeon HD 4890, AMD continues to enhance its "Dragon" desktop platform technology, designed to provide exceptional value to OEMs, channel partners, and do-it-yourself (DIY) consumers.

"The ATI Radeon HD 4890 graphics card represents the AMD sweet spot strategy reloaded," said Rick Bergman, senior vice president and general manager, Graphics Products Group, AMD. "With last year’s launch of the ATI Radeon HD 4850 and ATI Radeon HD 4870 products, we gave gamers great performance and an incredible value proposition. Today, we’re doing it again. ATI Radeon HD 4890 graphics cards are incredible performers, priced to sell in all major markets worldwide."

The ATI Radeon HD 4890 graphics card continues AMD’s proud tradition of technology leadership with support for the latest DirectX 10.1 games, including Ubisoft’s Tom Clancy’s H.A.W.X., Electronic Art’s BattleForge and SEGA’s Stormrise released last month, as well as GSC Gameworld’s S.T.A.L.K.E.R: Clear Sky. When compared to DirectX 10 game play, DirectX 10.1 games have proven to deliver higher game performance and an improved visual experience.

"The new ATI Radeon HD 4890 graphics card could very well be the must-have gaming product of this spring," said Adrian Thomson, vice president, Marketing, Sapphire. "With breakthrough levels of game performance, cutting-edge feature support like DirectX 10.1, and high degree of performance tuning flexibility, the ATI Radeon HD 4890 is one of the best performers in its class."

Making the best even better

The ATI Radeon HD 4890 graphics card delivers exceptional value to gamers, handling even the most intense games at high resolutions and image quality settings. For overclocking enthusiasts, the ATI Radeon HD 4890 offers tremendous performance tuning potential. Those looking to get even more performance out of their gaming rigs can combine as many as four ATI Radeon HD 4890 cards in one PC utilizing ATI CrossFireX technology.

"Gamers that want The Ultimate Visual Experience demand the best performing card, and our new ATI Radeon HD 4890 graphics cards will give them exactly that," said Eddie Memon, vice president, Marketing, XFX. "With the new ATI Radeon HD 4890 we’re approaching the holy grail of clock speeds, targeting 1GHz, achievable through XFX’s superior design and the quality of the new graphics processor from AMD."

ATI Stream technology

By harnessing ATI Stream technology in combination with a number of ATI Stream-enabled applications, the ATI Radeon HD 4890 graphics card can also help accelerate the conversion of standard and HD video into multiple formats for use on differing consumer electronics devices. CyberLink, an innovative software developer for digital media creation, playback, and sharing applications, has optimized its award-winning video editing software, PowerDirector 7 to make use of ATI Stream technology. The recently released update to PowerDirector 7 incorporates ATI

Stream technology to provide GPU accelerated video conversion, featuring higher levels of performance and functionality when compared to CPU-only acceleration.

"CyberLink is committed to helping consumers create digital content quickly and easily," said Alice H. Chang, CEO of CyberLink Corp. "PowerDirector 7, Cyberlink’s award-winning video editing software, takes advantage of ATI Stream technology, making a great experience even better. With PowerDirector 7 and ATI Stream technology, anyone can edit high definition video, create an amazing movie, and encode it for playback on virtually any device faster than ever before."
