ATI’s New Chip May Be Around the Corner

---

:slobber:


Sorry if this has been posted already.

so when can we expext r580?
should i wait for it or should buy r520?

it is vapor until I can find it and buy it...

Q1 at the earliest guys...

knowing ATI its the very last day in Q1 at the earliest, at around 5pm when shops are shut. :rolleyes:

They will use a lot from the R520 architecture I suspect. One of them is the memcontroller which was an entirely new design for the R520. Many things like powerleakage an thus bad yields will be sorted out because ATI is learning a lot from the R520 at the moment.

The R580 is the big brother of the R520; the R520 is not even family of the R420 and R480.

R580 is actually based off of the x1600xt IIRC. It's essentially that core with 16 pipes instead, giving it a total of 48 alu's.

It's based on the idea of the X1600, and that's not hard to see. Except this time there won't be major bottlenecks within the architecture.

It's basically the x1600, with 4 quads instead of 1.

I don't care what ATi claim, the X1600xt is a 4 pipelined card, it just had 3 alus per pipe, so they called it a 12 piped card. It's kind of like the FX 5900 and 5800 were 4x2, except unlike NVidia(who called it 4x2 instead of 8) ATi lie and call it 12.

The R580 will be 16 pipes with 3 alu's a piece. If you'd like an idea of the performance difference, take a x1300pro and a x1600xt, lock down 3 vertex shaders on the x1600xt, and drop the memory down to 800mhz. That'll tell you the difference.

We still dont know for sure what r580 will be.

NVIDIA did lie. They made everyone think the FX 5800 was 8 pipes to hype it against the 9700 Pro.

How come that ATI's products always leak info (not the products leak info ofcourse, you get the point)...yet it was 2 weeks ago that we heard the first real news about the 512mb GTX?

You'd almost say ATI does this on purpose to advertise for their upcoming card....and then nVidia just does it again with a monster card....I wouldn't be suprised... :D

But there is always something better around the corner...especially in GFX land....I'd had enough of waiting so I'm gonna get a 512mb GTX :)

I don't know about that... I know my dad had a FX5900(he's completely anti-ATi , I remember trying to explain to him the 9800pro owned it..one of the poor souls that actually bought the old Rage128), and the box said 4x2, not 8. Load up rivatuner with a FX card, it'll tell you the same... I never read anything claiming the NVidia card to be 8, only 4x2.

This could mean an increase from 9k stock in 05 to between 12 and 13.5k stock for the R580, assuming its using GDDR3 memory. If we add in the prospect of GDDR4 memory, we're looking at anywhere from 14 to 15k stock in 05, which would be a cautious estimate.

So yes, by q1/q2 2k6, 05 will have become the new 03, with ~20k+ a reality with SLI/Crossfire.

x1300 = 600mhz, 4 pipelines, 2 vertex shaders, 800mhz ram, 4 Z-Compare units.Standard memory controller
X1600xt = 590mhz, 4 pipelines with 3 alus each, ringbus memory controller, 1.38 ghz on the ram, and 5 vertex shaders, 8 Z-Compare units, ringbus memory controller.

There's more to the difference than just the 4x3 between the x1300 and x1600.... If you expect 30%-50% difference, you're out of your mind! It'll be like the difference between the 9700pro and 9800pro, just like Metro.cl has said many times. Considering all these difference doesn't even always add up to 50%, you surely can't expect simply giving it 2 more alu's per pipe to add up to that much!

Well I just remember reading a lot of reviews of those cards at first claiming it had 8 pipes, leading me to believe that's what NVIDIA told them when they gave them the specsheet and such.

if the R520 has more than 16 pipes on it I wonder if ATI really only has 16 pipes on this R580 to save on transistor counts because they figured out that's the most they can handle in decent yields.

the r580 seems to improve the pixel pushing power of the r520 whilst keeping the same vertex processing. Essentially this cuts out one of the r520's weaknesses compared to the g70, but its not an improvement that will benefit all situations, but should help in those situations where the 7800gtx outguns the xt. If however they can also improve the clocks of the core and memory, or even improve leakage it will certainly be worth it, but until some solid information on working chips is avaliable, theres no way to guess what the actual tangligable benefits of the r580 will be over the r520.

Also the 80nm process that will be coming into effect post r580 is just an optical shrink of the 90nm process, useful for making chip cheaper, but not really liable to increase clocks. Especially considering the first 80nm processes are liable to be aimed for lower cost value chips, where high yield and low cost are more important than performance. Its likely that the process would have to be tweaked somewhat before its suitable for high end parts. As such, you have to wonder if even r600 will be on a 90nm process (although it should have matured somewhat in the next year).

I thought we had an understanding that all non-factual speculation related thread would go in the Unofficial ATI News thread...

ALL ATI related non-official news and discussion that has no solid evidence (like a pic or something) belongs shere.

Havent seen any info at all about crossfire before..

Latest rumours on r580 from mydrivers.com (Translated)

Before we already reported ATi was grinding sends the R580 graph chip the news. Now acts according to the news which divulges indicates, the R580 graph chip uses 13 metals in the craft interlocks, ILD, uses the improvement the Low-k craft and the gap compound excessively level, by further promotes the operating frequency. Some hearsays indicate, because between TSMC and IBM has the technology exchanges the agreement, but TSMC again is the R580 generation of labor merchant, therefore IBM in G70 when usefully arrives partial technology, also will appear in R580.

The hearsay points out, R580 and RV530 same, uses the picture element exaggerates the pipeline and the texture unit separation formula design. Under the traditional overhead construction design pattern, the single scroll picture element exaggerates the pipeline contains covers all exaggerates the process, the R580 design and this traditional design is different. ATi starts from the R300 graph chip, each picture element exaggerates the pipeline all matches 2 ALU, 1 entire labor, 1 part time worker. ncVidia G70 each picture element exaggerates the pipeline matches 2 entire labor ALU, therefore with G70 similar, the R580 graph chip will have 48 picture elements exaggerates the pipeline, will amount to 96 ALU, 16 textures units. Moreover, the hearsay indicates, in ATi plan RV560 will have 24 picture elements exaggerates the pipeline, 8 textures units. At present RV530 has 12 picture elements exaggerates the pipeline, 4 textures units.

The hearsay indicates, R580 will not greatly possibly promote in the near future, but will be can issue around the next year spring Cebit2006 congress. Certainly R580 final specification and issue date or must official tell us by ATi.

according the MSRP of the X1600XT has been lowered from 249 to 199 euro/dollar.
this to better compete with the 6800GS.

First i thought the X1600XT performened so bad cause of bad drivers wich didnt yet unleash the full power ofit. but seeing ATi lowering the price of this card by 50 euros even before it can b bought makes me think that maybe this card is just a lame duck.

Hmmm....niceee :) If MSRP is $199...I have my fingers crossed for a $175 X1600XT few days after launch :D :D
