Originally slated for 22 November, AMD's upcoming Radeon HD 6900 series featuring the company's new enthusiast-grade "Cayman" GPU core reportedly ran into delays. A more recent report by VR-Zone suggests that these delays are not because of any yield-issue related to the GPU, but shortage of a new high-grade driver-MOSFET (DrMOS) chip used on the reference board, sourced from Texas Instruments. The said component looks to feature a more compact package compared to the ones commonly made by Renesas and the likes, which is why AMD seems to have chosen it. The TI-made component is in short supply, and is a very recent introduction by its makers. AMD has a knack of using exotic and high-grade components on PCBs of its high-end graphics cards. A driver-MOSFET is a component that combines the driver IC, and MOSFETs into a single package.
