According to this Digitimes report, the upcoming revision of the Phenom 9600 and 9900 CPUs with the TLB fix to address performance issues is going to be pushed back until Q2 of 2008.  Their sources claim that AMD hasn’t been able to solve the bug and if this turns out to be true will be very bad news indeed for a product that hasn’t even seen day one of sunlight.

AMD has recently notified its partners that the launch of higher-end quad-core Phenom processors, including the 9700 and 9900, will be postponed to the second quarter of 2008 from the original schedule of early 2008, according to sources at motherboard makers.

However, whether AMD’s triple-core Toliman series CPUs will also see delay will be the key decision for the company, since Toliman offers a high price/performance ratio compared with Intel’s quad-core CPUs. A delay for Toliman will hurt AMD the most, noted the sources.

The sources commented that the reason for the delay of 9700 and 9900 is because AMD has not yet been able to solve the translation lookaside buffer (TLB) erratum found in the chips. However, they added in saying that, in the long-term, AMD’s decision is correct since pushing products that are not ready will only hurt the company more.

AMD declined to comment on this report. The company pointed out that it has not made any official announcement regarding a delay of the mentioned CPUs.
