http://www.semiaccurate.com/2009/09/15/nvidia-gt300-yeilds-under-2/ The source isn't the greatest but I thought it would be worth discussing. The figure sounds way too low to be true so I think its BS. Whats your take on this?
That blog has been referenced here before, and the author was promptly denounced as an ATI fanboy, or at least someone with a very significant anti-nVidia bias. I wouldn't lend any weight to what he has to say TBH.
Hmm... I notice he always seems to pull facts and figures from nowhere as well. Once I see several credible references I might be inclined to believe him, but where would figures like this come from? It is not as though Nvidia would release them if it was this bad... Charlie if full of a lot of pent up Nvidia hate... I wonder if he walked in on a GeForce 4 and his mother?
To get such low yield the finger has to be pointed at TSMC surely, they provide all the verification flows and will also go through yield simulations with you via the on-line service, last time I heard of yields that bad it was because the fab needed to do some tweaks to their kit. Although I have heard some class stuff from some companies recently regarding DFM like not bothering due to wasting die area (its such a negligible impact, well for the stuff I do, doesn't make sense) , perhaps NV took that approach, more fool them. I suppose the size of the thing is whats killing it, so much to go wrong.
Guru3d also think there is enough juice in this rumor to post it on there site. http://guru3d.com/news.html#10007 They do stress that it is rumor though. Fudzilla say Nvidia are confident the GT300 chip will beat the ATI chip but that dosn't mean to say the rumours of low yeild are not true... http://www.fudzilla.com/content/view/15535/34/ The low yeild problems have been heard claimed by numerous sources now.. while it may be all bollocks, you know what they say, "no smoke without fire"
I have no doubt nVidia are having yield problems but this fanboi is off his rocker if he thinks the yield is as low as 1.7%
Guru 3d report the same rumor. http://guru3d.com/news/nvidias-gt300-yields-pretty-bad-/ It's not unthinkable if there was a fault somewhere in the process that was causing poor uniformity or a whole range of other problems that a yield of zero or 1.7% would come out there test batch..
Its not 'Nowhere' that he pulls his facts from. Its somewhere a lot more personal if you know what i mean.....
Just notice it is a discussion by a ATI fan or AMD fan,make a disadvantage topic surely.I am GeFans ,don`t mention it.
The yields are in reality such, that TSMC and Nvidia are now, as last resort, jointly praying for a miracle, ups, I mean deliverance. If the mentioned does not occur, we will probably sooner see the 28/32nm process, as satisfying prices for the GT300 chip. What concerns the author in the question above: he is rotten within. It's not just Nvidia, it's his manner of doing. I wonder, what he does for living.
