Rumours abound that AMD is going to miss its original November launch date for the Radeon HD 6950 and Radeon HD 6970 GPUs, leaving the market to rival Nvidia and its new GTX 580 for another month at least.
Although the company is still officially sticking to the 22nd of November as the GPU's launch date, claims of component shortages and hardware partners failing to receive their boards are leading many to conclude that AMD will be announcing a delay closer to the time.
The problem, according to an unnamed source quoted by VR-Zone, is due to a reliance on a Driver-MOSFET, or DrMOS, supplied to AMD by Texas Instruments. Found in both the Radeon HD 6800 series and the upcoming Radeon HD 6900 series, it's an integral component - but it looks like TI is running out.
As a result, it's unable to meet AMD's demand for DrMOS components - leaving AMD forced to use its limited supply to build its already-launched Radeon HD 6850 and 6870 boards and delay the launch of the next-generation Cayman-based 6900-series.
So far, AMD isn't commenting on the rumour - but it's a worrying time for the company's hardware partners, who reportedly won't be finding out whether they'll be able to launch before December until the end of the week.
