Why ATi R520 Delayed?

An article over at Penstarsys suggests that ATI is facing some yield issues
with their R520 that leads to the delay and here’s their take :

"The information on the R520 suggests that there are some extreme yield
problems with the current design. Not only are there few working dice per wafer,
but a large number of those dice only have 16 pixel units working, and others
are lucky to get 24 working. The information I received suggested that the R520
was in fact designed with 32 pixel units (each with multiple ALU’s), but due to
the issues that the chip is facing, very few of them so far are fully
functioning. There are of course fully functioning parts that have been shown
behind closed doors, and apparently Abit showed off a working card at ACon5 that
scored some impressive 3DMarks."

Ed’s Note : Another side of the story we heard from the graphics cards
makers that R520 is delayed due to ATI is trying to offload more X850 GPUs
before releasing R520. ATI has chalked up a considerable large inventory of X850
GPUs therefore they are hoping that the recently launch of Crossfire editions
will help to clear up the inventory. R520 will launch in late July as we have
reported and the earliest availability of the R520 cards should be mid August.
