Con il comunicato stampa di seguito allegato, ASUS ha annunciato le proprie schede grafiche Radeon DirectX 11 di seconda generazione nell'ambito della linea EAH6800, che include al momento la soluzione denominata EAH6850 DirectCU/2DIS/1GD5 (basata sulla Radeon HD 6850) e la EAH6870/2DI2S/1GD5, che è invece equipaggiata con la gpu AMD Radeon HD 6870.

ASUS sottolinea che la EAH6850 e la EAH6870 sono implementazioni "overclocked by factory" della Radeon HD 6850 e HD 6870 rispettivamente, dal momento che le gpu di tali schede lavorano a 790MHz e 913MHz, mentre i corrispondenti valori reference sono pari a 775MHz e 900MHz. Inoltre, il regime di OC può essere ulteriormente estremizzato con l'ausilio della tecnologia Voltage Tweak, che stabilizza gli overclock spinti mediante l'overvolt.

L'equilibrio termico viene garantito, nel caso della EAH6850, con la tecnologia proprietaria DirectCU: in accordo alla denominazione, le heat pipe in rame sono poste a contatto diretto con la gpu, favorendo così l'assorbimento dell'energia termica generata da quest'ultima. Rispetto al cooler reference, ASUS dichiara un calo della temperatura di esercizo pari a 20°C.

La EAH6870 è invece arricchita da un cooler con copertura in alluminio (quello reference, di forma e struttura analoghe, include invece una cover in plastica, ndr); la soluzione di ASUS migliora l'efficienza in fase di smaltimento del calore; la temperatura, in prossimità della superfice del PCB, risulta ridotta di 15°C rispetto a quella monitorata con il dissipatore reference.

Featuring even more processing power than the successful EAH5000 Series of graphics cards, the new ASUS EAH6800 Series continues to serve PC enthusiasts with cutting-edge technology and a range of exclusive performance-boosting improvements to the AMD reference design.

Both the EAH6850 DirectCU/2DIS/1GD5 and EAH6870/2DI2S/1GD5 cards feature AMD Eyefinity multi-display technology, AMD HD3D technology and DirectX 11 support. In addition, exclusive Voltage Tweak overclocking technology offers a 50%* performance boost over the reference design. The EAH6850 DirectCU and EAH6870 also ship with factory overclocked cores set to 790MHz and 913MHz..

The ASUS EAH6850 DirectCU also incorporates exclusive DirectCU cooling that uses custom-flattened, all-copper heat pipes in direct contact with the GPU core. This improves cooling by 20%* compared to the reference design and offers quiet operation when the card is idle. The ASUS EAH6870 is equipped with an aluminum fan cover that improves cooling efficiency and reduces surface temperatures by 14 degrees Celsius, compared to the reference design’s plastic cover.

• Exclusive ASUS Voltage Tweak technology offers real-time voltage adjustment of various GPU components, including the core and video memory, making ASUS EAH6800 Series graphics cards 50%* faster than the reference design.
• The EAH6850 DirectCU is factory overclocked to perform at 790MHz. This is 15MHz higher than stock performance, resulting in higher frame rates in games.
• ASUS proprietary cooling technology, DirectCU, puts copper heat pipes in direct contact with the GPU core. This results in the EAH6850 DirectCU running 20%* cooler than the reference design.
• The EAH6870 features a stylish aluminum fan cover that dissipates heat more efficiently. This lowers surface temperatures by 14 degrees Celsius, compared to the reference design’s plastic cover.
• Proprietary AMD Eyefinity technology supports up to six** displays for a fully immersive viewing experience.
• AMD HD3D technology for stereoscopic 3D gaming and movie watching.

* Subject to system configuration and usage. Results may vary.
** DisplayPort 1.2 compatible monitors required for six-screen AMD Eyefinity output. Please visit www.amd.com/Eyefinity for more information.

ASUS EAH6800 Series graphics cards are expected to ship October 22, 2010 and will be available from authorized ASUS resellers.
