ATI R600 Taped Out

[Capt Caveman]

I didn't think DirectX 10 was finalized yet.

http://www.theinquirer.net/?article=32546

"WE JUST learned that ATI managed to tape out its next big chip. R600 is taped out and it works well, we're told. When we say big, it will be physically big, very fast and very marchitecturally advanced.

It is the first of the DirectX 10 bits of kit from ATI and we expect it to appear some eight to ten weeks after Nvidia's G80.

It looks like everything is on schedule for now. The company has time to tape it out again and it can still meet the Q4 2006 deadline but let's hope it doesn't have to do it.

We are unable to confirm whether Nvidia has taped out the G80 but if it wants to meet its September-ish, Octoberish deadline its shoudl have done by now.

We know that Nvidia might not have the real unified Shader while ATI will, but only time will tell which approach is better."

It'd be great if its true. First DX10 card with unified shader!

 

[DeathReborn]

Physically big eh... bigger than the R580? If so then pretty pricey & most likely water cooling as standard. Still good to see a tapeout go well for ATI, maybe it'll come out earlier than expected.

 

[hardwareking]

i don't think it'll come earlier than expected.cause r580+ will be enough(hopefully)to deal with g80 and the gemini radeons can deal with the 7950 gx2 or 8950 gx2(as it maybe called).
And whats the point of a fully dx10 compliant card if there are no games which use it?

 

[Ika]

why would it matter? performance will almost suredly be on par with current gen cards, or even worse.

and, as always... source is inquirer

You septics have a lot to answer for, Guantanamo, Kyoto, your tendancy to bomb first identify later...

But nothing compares to the continued butchery and torture you carry out on the english language every day :| [/rant]

I now return you to your regulary scheduled thread.

to be honest, I'm not sure how much faster R600 will be than the X1900 series. in terms of total shaders, the X1900 has 48 pixel + 8 vertex, or 56 total, while the R600 has 64. That is hardly an earth shattering increase considering the X1900 almost tripled the X1800's shaders, and yet performance wasn't increased by more than 20% in most cases. Also, from what I've read, because of the additional overhead of a unified shader, each one is slightly less efficient than a dedicated pixel or vertex shader. There are advantages, like the ability to dedicate more vertex shaders in very vertex-shading heavy games, but for traditional games, where there is much more pixel work than vertex work, there won't be much of an advantage.

Also, why do we keep increasing pixel shaders without bumping up the number of actual pipes on new cards? We've been stuck at 16 since the 6800/X800 days. What good is having 64 shaders if there are only 16 ROPS to feed them through? I know that a ratio of 3:2 worked well for nvidia with the G70/G71, but there are obviously deminishing returns with anything beyond that (i'm sure the X1900 can't reliably keep even half its pixel pipes busy with its ratio of 3:1), and I'm sure it'll be the same story with the R600's ratio of 4:1

ATI obviously needs your help.

What are you British? I don't know how you spell "tendency" and "skeptic" over there but if it's the same way we do here, you're not one to talk.

I think he DID actually mean to say "septics" and NOT "skeptics". "tendency" of course is spelled wrong.

 

[Polish3d]

Ahh well. I'd rather talk about R600 and G80... anyone with anything on their specs? Not that most even guessed G71 correctly but..

For which i blame my parents and the faulty genes they handed down. Septics was intentional, tendency would be the mis spelling of which i am accused.

"marchitecturally"

Edited because i messed up the quotes

 

[LittleNemoNES]

It will be interesting to see how ATI or NVIDIA see Dx10. I would think that ATI has the edge because of their work with MS on Xbox360

i'm not quite sure where Fuad is from, but he was the first person to use that term, afaik, and the inq is british. so there is a good chance that fuad is at least somehow connected to the UK.
inq's glossary, where they claim 'marchitecture' is their term

Lol. What were those dense engineers thinking? ATI could save so much money by just employing gobucks as their design engineer/specialist.

All right, sarcasm aside we still don't know the hard specs of R600 or G80, unless I've missed an official announcement. I'm sure there will be a performance increase, how much is yet to be seen.

inq's glossary, where they claim 'marchitecture' is their term

"ENF may be real, but the notion of a link between ENF and IMS products is overblown in Braude's eyes. 'It's what I call 'marketecture,' ' the Gartner analyst says."
?Ralph Carlyle, "Assessing Computer Associates' new architecture," DATAMATION, August 1, 1990

It's an outgrowth of the american buisness practice of making words up for no apparent reason.

Although most of my point is oblliterated by having the inq based in the UK

Edited for quotes again.

Well this is not concrete but it's been there for a while now: http://www.xbitlabs.com/news/video/display/20060525104243.html

The code-named R600 visual processing unit may repeat the success of its grand-grand predecessor, as, according to sources familiar with the plans of ATI Technologies as well as some media reports, ATI R600 will have 64 unified shader processors ? an unprecedented number so far, 16 texture units ? inline with today?s GPUs, clock-speed beyond 650MHz and support for high-speed GDDR4 memory controller. Rival Nvidia G80 will have lower amount of shader processors and will also have ?hybrid?, not unified, micro-architecture. Neither ATI, nor Nvidia commented on specs of future products.

I think my name is in the wrong place of the quote there.

anyway, i'm of the opinion that the xb360 runs dx10, or something close enough to not matter, so that ati (which worked closely with MS to develop R500, i'm sure) knows what will be in dx10, so they can get a dx10 R600 out pretty easily

 

[Munky]

Ati said the r600 will also have the highest DX9 performance of all their gpu's to date, so I expect it to be faster than any version of the r580. Granted, 64 shaders vs. 56 shaders doesnt sound like much of a difference, but then again a 16 shader r520 didnt look all that impressive on paper compared to a 16 shader r480, and yet it offered a big jump in performance.

 

[thilanliyan]

In the unified architecture, can more resources be dedicated to to say textures versus shaders and vice versa?? (ie. can it act like a 30 "traditional" pipeline part??)

 

[LittleNemoNES]

Does having a unified architecture mean that HDR and AA can be enabled always? Or another example soft shadows and AA in FEAR? Or Proper AA in GRAW?
