AMD has officially confirmed the delay of its Phenom 9700 and 9900 processors, multiple outlets say. The quad-core chipsets were due to ship in the first quarter of 2008, but are now being pushed into the second quarter, as sources out of Taiwan hinted in December. AMD denies, however, the suggestion that the the problem is with the chipsets' translation lookaside buffers (TLBs), an issue which has also affected the company's Barcelona server technology.

A spokesman is quoted as saying that AMD made its decision based on "OEM and partner input," as well as "prioritization and resources." To compensate for lost sales, the company will instead focus on its triple-core processors, which straddle a gap between performance and price. The company will also launch new Phenoms with low power consumption, and one other quad-core CPU, the 9000E. [via ZDNet]
