It looks like there may be even more bad news for Sony fans waiting for their Playstation 3s. Apparently IBM is having issues with Cell chip yields. IBM vice president of Semiconductor and Technology Services Tom Reeves says they are only getting 10% to 20% yields, which is terrible. Right now 1-2 out of every 10 cell processors are working properly after they are manufactured. For the Playstation 3, Sony requires 7 of the 8 cores to work and IBM say that on most of them, only 4 of the 8 cores are working. There are also rumors around the internet that they are considering pushing the launch date back to March 2007. Considering the current yield issues, I would not be too surprised if those rumors turn out to be true. For more info on the cell problems, check out this article.
