Barely 24 hours into the launch of the Radeon HD 4770, ASUS has announced its factory-overclocked, and overclocker-friendly variant of the ATI Radeon HD 4770 (model: EAH4770 TOP/HTDI/512MD5). Giving it the "TOP" branding, the company upped the clock speeds, and backed the product with its Voltage Tweak technology, and its popular SmartDoctor performance control application. The gains end-users have compared to using a reference design accelerator are two fold.
First, ASUS set the clock speeds at 800 MHz (core), and 850 MHz (memory), both 50 MHz bumps over the reference AMD clock speeds of 750/800 MHz (core/memory). Second, using the value-added features, the voltages can be upped from 0.95 V to 1.2 V, increasing the overclocking headroom. ASUS claims the core could be set at freqencies as high as 971 MHz, and 1150 MHz for the memory: a seemingly massive increment over the reference speeds, which ASUS rounds off as a 35% speed improvement. The card retains the reference AMD design, and the most common cooler design partners are currently using. Its pricing and availability are yet to be known.
