Shortage of GDDR5 or RV740 chips?

[bupkus]

Posts suggest the popularity of the ATI's new HD 4770 account for supply shortage, but this is more than a shortage. Nary a one is available online anywhere.

Some suppose a problem in the supply chain due to the 40nm process, but wouldn't there be some?

However, none have suggested a shortage of the newly released GDDR5 memory chips. If there's a problem with GDDR5 supplies I would expect at least some 4770 cards to be popping up here and there.

So, can it be that a cut off date had been defined whereby GDDR5 chips would then go elsewhere, perhaps to the also popular and maybe more profitable 4870 or 4890 cards?

If the new 40nm process is now understood to be such a killer product process then we must first flush out the old 55s?

I know; I have too much time on my hands. :roll:

That's a bummer for AMD. They took a risk pushing the release of a 40nm part so early into the yield discovery phase of the ramp at TSMC...but without risk you lose opportunity so they had little choice.

ronnn's link spot-on explains the conundrum, but for your future reference know that this particular scenario you laid out in the quote above could never happen in the industry. GDDR5 contracts are not structured with cutoffs or anything resembling the concept as you describe it.

You can have supply disruptions, but they aren't usually done intentionally or as a matter of contractual obligations. That's grounds of lawsuits, its just never done that way.

I must have misstated as my intention was to mean that perhaps ATI had diverted their stream of GDDR5s coming from their supplier to a their........😕
On second thought, they don't actually manufacture these cards, so their builders can build whichever 4xxx model they choose.
Never mind.
Thanks, ronnn, for the link.
