hmmmm were did i see those specs before.....hmmm let me think .....
heh...i saw these specs about three months ago and i don`t think they are real...
For me 700Mhz core is impossible to get....
3 times faster over x800xt-i don`t think so...Why???Because ATi must sell present cards based on r420 and when they will release card which will be 3 times faster over the one of the fastest graphic card nobody may buy cards like x850 x850xt pe....
For me these specs are 99% impossible....They may be real but not now
EDIT:There you are these specs..They were said in November last year....

These are BS specs.
There is no way in hell.

You guys are the ultimate BS detectors :D

Why did anand post it... I mean it is pretty obvious that this is nearly impossible.
WOW 3x the performance of the X800XT !! :eek:
Not gonna happen.... not this generation at least. :bleh:
Well we used to see a double performance trend from ATI.

24 "Pipelines"
32 Texture Units
Whats wrong with that picture ; )

Why is it so hard to believe, they have moved to a 90nm process which leads to lower temp, (assuming I am right in thinking they are using a 130nm process now), so higher core frequency and ram makers having been ramping up GDDR3 for quite a while now? Also they doubled the 9800 PRO which was only one generation back and who knows how many more X800 refreshs are going to come out, (I smell X880)? And how is it impossible? I am sure ATI and Nvidia are probably aready using cards this powerful in house by now. They develop what, 3 generations at the same time?

Well from experince from AMD and Intel when they switched to 90nm they surely did not lower their temps, and infact they both raised them. Next is the fact that modern GPU/VPU's are much larger than P4's or a64's right now, so they not only face haveing a less mature 90nm processor from TSMC, but they have to worrie about a much larger chip size.
Its still possible that they could infact use 90nm, however it is not going to give magical gains like everyone is hopeing.

You left out the 9800Pro and XT...
I'm talking initial releases, not revamps of existing architecture.
9800 pro was just a tweaked 9700 pro.
I'll believe double the X800XT performance, but not triple, not for another year or 2. With the right setup, I believe a 24 pipe card running 700mhz will be close to twice as fast as the X800XT, but nowhere near triple.

Those were revisions. He's talking about new chips. The specs seem highly possible to me, look at a Nv40 ultra vs a NV35.

Nvidia did say that this was the largest performance leap they've made and yet they "only" attained 2x performance not 3x. There's always a possibility but I don't want to get all excited about it. It really doesn't seem possible though.

The only part I find really pushing it is the 700mhz, 1800mhz, 512mb, and 3x performence. I pretty much buy everything else.
Ok this is what i find odd, the r520 is meant to be 6 quad GPu with each having 4 pixel processing pipelines....thats 24 in total, each Pixel pipeline has how many texturing units? That rumour says 32 units in total, erm so some have 1 and others 2? or what? I dunno?
700mhz at 90nm at first go maybe a bit optimistic, maybe 500 MHz? that with a 350 million transistor die...and as prescot showed, 90nm has a lot of problems with leakage.

Aye there is not way core will be 700Mhz , remember all the hype with NV40 and X800+ line of cards crazy numbers and insane memory never happend ! .
Best we can except is 400 Core with 24 pipes and probably 1200mhz memory would be good. ATI,NVIDIA always play conservative they will never use fastest memory available.
yeah.. the core clocks seems extremely high.. for a new chip.. and the 3x performance it wishfullthinking.. with that kind of specs..
24xpipes at 700 mhz in 256bit bus memory?
if ATi is lucky enough they will get 2xtime the x800XT performance.. not more. same with Nvidia.. To achieve 3x times the performance of the fastest today generation they need a lot more than transistors and pipes.. but something completely new never seen before. at least not in the NVidia and ATI life. howerver it will be nice if those specs were true. :)
I don't find the core being so high as a surprise. I say this becuase of the technology that ATI purchased about a year or two ago. I forget the details....could never find a link for it...but being a Rage follower for a while I remember it being a big deal. Some sort of process/tech that allows for higher clocks than they would yeild through traditional manufacturing. Supposedly it wouldn't be hard to hit 1.4gigs with the tech. If they indeed purchased a liscense, I'm sure they'll use it.
If anyone else remembers this, please elaborate so I don't look completly insane.

That would be Low-K and SOI , manufactureing process'es helps eliminate err.. lower power leakage and achive higher speeds at lower power consumtion.
However even with that i realy don't think they can hit that high of clock's , unleass they somehow mastered Manufactureing process :p .
LOW-K was what I was thinking of....I didn't remember them going with SOI, though...hmmmm.
Actually....I'm fairly certain they'll be able to hit 700.
The more high end parts they come out with, the less availability thier parts seem to have. By the time this card comes out, they'll only have to produce like 3 or 4 that can reach those clocks.
=D
Does TSMC offer low k on 90nm? can anyone confirm that?
