Cayman reportedly plagued by manufacturing issues

Written by


TSMC stuck at single digit yields
As we reported on Friday, AMD's upcoming Cayman appears destined for a delay or a paper launch, as some partners have still not received the boards, or final bios versions.

According to TechEye, the delay was caused by poor yields, which is supposedly in the single digit range. This is somewhat surprising, as the 40nm process is rather mature. Nonetheless, building a 3 billion transistor chip was never going to be easy, a fact clearly demonstrated Nvidia's GF100.

Taiwanese sources told TechEye that there was only a slight chance of AMD keeping its schedule and shipment targets in Q4. Cayman was originally scheduled for a November 22 launch, just in time for the holiday season. We can only hope that AMD and TSMC will manage to work out the kinks plaguing the new GPU in time to start volume shipments in early December.

AMD needs to send engineers to TSMC to iron out the difficulties and not make NVIDIA's mistake with the GF100 who waited too long to intervene directly.

What do you know, 6970 is following Fermi's destiny...

Sounds bogus!

Yeah... I don't believe this... sounds like foul play or fud to me.
Near flawless launches on new nodes, since the HD4870 then all of a sudden... this?
Na, I don't buy it.

If it is true, they need to get their butts over to Glo-Fo & see if they can make it.

TSMC have made a whole generation @ 40nm for both AMD & nVidia, have started well on both companies next gens (68xx / 580) & now this? It's bull.

No disrespect to fudzilla of course, they only say what they hear...

I got 74 thumbs down for telling that Barts was the 6800 and for merely hoping that this time ATI wouldn't have had problems with yields

Naah...with the 6800 series available in such quantity from the start I doubt the 6900 series even though bigger would have such problems on a now mature process. More pre release BS.

We will know better than November 22, if the market is plagued by Cayman then Fudzilla and its rumor sources were wrong.

Some reports says Cayman is already sampling to partners and is on schedule.

The greater the risks the greater the rewards. I honestly think AMD and Nvidia should roll out mid-range cards first and then as the technology matures attempt the higher end cards.

They probably hold back the BIOS to counter the GTX 580 with a few percent performance boost...

Sounds like a prime example of FUD to me…
