Well that doesn't make much sense....theoretical fillrate is ~7% higher with the 32 pipes and it would seem that 32 pipes would be a good selling point or something....go figure.

Upon further pondering....I want one to put into SLFire with my 7800GTX....

Many AIB partners have received the ATi Radeon X1800XL (R520XL) card samples last Friday and the die size seems to be larger than the R520 sample we received previously. The die size is enlarged from 18.2cm x 19cm to 19.3cm x 19cm so ATi has re-taped the core and added some features unknown to us at this point of time. ATi will be unveiling R520 officially on October 5th but we do not expect mass production of the cards till end of Oct. So far we heard only 1K of such cards produced for customers qualifications and reviews. Yield rate for 16ps and 24ps R520 is under 25%.

only 1000 cards produced?! Under 25% Yield rate? :slapass: :down: :yawn:
just show screenshots with score from 3d01 3d03 & 3d05
then we can talk about ati and how they did.
Also a 32pipes r520xt when r580 is ready to go is stupid
can't say i haven't seen it coming :rolleyes:Quote:

Also, I remember reading some article like 6-8 months ago where ATI had a R520 at some show. In this they also stated that it scored over 10k in 3d05. WTF happened to that card? If they said R520 was ready back then, then what are the chances that r580 is ready now. Slim to non-exsistent is my guess. Final verdict ATI is :banana: up.
That card still exists....they just can't make enough of them (and the die and PCB have changed since then). There ARE cards out there with 32pp, they just can't clock particularly high (killing the vertex pipes' capability since they can all be enabled). It seems to already be apparent that there is little dynamic clocking in this core--otherwise they would crank up the vertex pipes while keeping the pixel pipes lower. That at yields at 32pp are probably zilch, even at the lower speed.Quote:

That 10k 3DMark05 score was probably one of those, although I honestly can't say how.....

According to preliminary tests done by our friends at HKEPC, R520XT clocked at 650MHz core and 1400MHz memory will score ~8600 on 3DMark05 using FX-55, nearly 1K higher than GeForce 7800GTX at 430/1200MHz. If the R520 clocks run at 550/1200MHz, the score will be around the same as the 7800GTX. It is certainly interesting to see how the R520XTs in Crossfire performs. There is a 32 pipes version of the R520 as well but it can only be clocked at 520MHz and as a result it will perform lower than the 24 pipes R520XT @ 650Mhz core. Therefore ATi will not release 32pp version until R580 comes along.
:stick:
WTF...that's an overclocked score, BTW. default 600mhz, 13/1.35?
Yes, 32 "pipes". but the majority of chips do not run fast enough to compete with the 7800GTX, so the chip will be sold as the x1800XL, i think.Quote:

lol what part of mine did YOU not get. i was mearly agreeing with you, and pointing out the new info. :rolleyes:
i highlighted the 24pipe becasue of the info that says it scores 8600...so 10k WOULD be 32 pipes, at about the same speed. that would make you guess pretty much right on. must take one hella a cooler tho.
NO WAY the yield is under 25%
Just impossible. If this would be the case they will either ask 1000 euros per card or they would go bellyup. They'd have to scrap HUGE amounts of silicon and re-use them. A procces costing A ENOURMOUS ammount of money. SO if the yield would be 25% I'm sure they'd Rebin it (YES AGAIN) or just scrap it all at once...
it only cost $0.25 to make one chip...
Most of the cost is developement...
Ah I see lol, little misunderstanding there ;)Quote:

nn_step you think A grade silicon used to make high end chips is cheap? :stick: :hehe: :slash:
R&D is costly I know, but a chip does not cost .25 USD to make.
As said before me 300mm wafers alone cost A LOT of money.
The silicon undergoes refining, polishing, getting every single piece of garbage out if it, then being made into a pilar like item and then cut into wafers , you don't honestly think that production is cheap do you? And we haven't even come to the part where they actually put something ON the wafer....
I'm not saying a core cost 200 USD to make but still..... it isn't cheap and nor is the recycling procces of the failed chips.
BTW theres more to a chip then just the making :) as said the silicon itsself, packaging, also items that need to be dealth with
The more reasonable number I heard (cant remember where or in what context) is that most modernd GPUs/CPUs cost about $70-90 per die. At that rate you are looking at a loss of $210-270 per card. That has to be re-couped some how...Quote:

I also recall hearing that the 7800GTX costs something around $350 in total to make. So one could guess that the RAM cost anywhere from $100-150 in total + I dunno for the PCB maybe $50? And that ought to give you an idea of what the GPU costs to fab
