ATI Radeon HD 4890 1GHz
In a rare move of its own, AMD today launched a factory-overclocked version of its ATI Radeon HD 4890 graphics chipset. The move takes the 850MHz core clock speed of the standard edition and boosts it to 1GHz, rendering the new version the first graphics processor of any kind to reach the milestone. AMD claims that the simple shift boosts the peak computing power from 1.36 teraflops to 1.6 and is theoretically faster than NVIDIA's GeForce GTX 285.
Despite the extra power, AMD says the new 4890 can still run on fan cooling rather than liquid and theoretically allows more on enthusiast video cards that opt for more exotic cooling or other overclocking-friendly techniques. For Windows users, video cards are available through third-party builders like ASUS, MSI and XFX. Support for other operating systems isn't mentioned as part of the immediate launch.
