ASUS Radeon EAH4770 Series with Voltage Tweak for up to 35% Performance Boost




Following the success of its EAH4890 Series graphics cards, ASUS, the world’s leading producer of top quality graphics solutions, today introduced the new ASUS EAH4770 Series that also utilizes the revolutionary Voltage Tweak technology. With this cutting-edge innovation, users will be able to boost GPU voltages via the SmartDoctor application and enjoy up to an amazing 35% performance improvement with the EAH4770 TOP. Along with the latest GPU technologies that include a 40nm manufacturing process, DirectX 10.1 graphics capabilities, support for HDMI 1.3, CrossFireX, and Stream technology, the ASUS EAH4770 Series is evidence that high performance gaming and affordability can co-exist without compromise.

Equipped with Voltage Tweak technology and the SmartDoctor application, the ASUS EAH4770 TOP/HTDI/512MD5 raises GPU voltages from 0.95V to 1.2V, boosting GPU and memory clock frequencies from 800MHz to 971MHz and 3400MHz to 4600MHz respectively*. Such unprecedented performance upgrades help raise the EAH4770’s 3DMark Vantage Extreme Preset score from 3053 to 4147—an unbelievable 35% speed improvement as compared to any other reference designed board**. Gamers can now feel the adrenaline rush afforded by silky smooth, true-to-life graphics—made possible only with the ASUS EAH4770 TOP.

The ASUS SmartDoctor is an industry-leading overclocking utility that works in tandem with Voltage Tweak technology to enable users to manually adjust the GPU voltage on the EAH4770 Series. With just a few simple clicks, users will be able to enjoy astounding voltage boosts and performance upgrades—all without the hassle of re-flashing the BIOS at the risk of damaging the cards, or groping blindly for a overclocking button at the back of the chassis.

The EAH4770 Series also incorporates ATI Stream technology, which utilizes the massive parallel processing power of AMD graphics processors to deliver new capabilities that go beyond the traditional usage scenarios of graphics rendering and video processing. This enables better balanced platforms capable of running demanding computing tasks faster than before. By building a complete ATI Stream computing ecosystem, one that delivers the performance, applications, software and tools necessary, AMD and it's best partner ASUS together are poised to turn the vision of affordable application acceleration into reality.
