Hello

I am planning on building a new computer with a 8800, and have heard that the current direct x 10 cards from nvidia will not support future direct x 10 versions, like 10.1

This card is a direct x 10 card, in the future can it be that it will not support direct x 10.x? and in how much time from now, if one can know?

Is this true that older direct x 9.b cards did not support direct x 9.c? Someone told me so... if so what were the models? and if this true, then can it be the same with dx10?

Thanks for the answer

I don't know about the 8800, but the ATi R600 will support Dx10.1 and it's coming out very very soon! (The ATi card, not the Dx10.1 :P)

By 10.1 what do you mean?

Do you mean it supports USA (Unified Shader Architecture)? or something more? because the 8800 also supports that.

Dx 10.1 supports the following

*Small improvements for important problems
*Limited to small hardware changes
*More VS→GS inter-stage registers, VS input
*Cube map arrays
*Multi-sample control (patterns, alpha to cvg)
*Better multi-sample color & depth access
*Per-render target blending modes
*API/runtime enhancements for multi-core
*Precision improvements

I also heard it makes use of multicore and also features less calls to the CPU for reflections and refractions, making it less CPU dependent.

from the 'limited to small hardware changes' statement we conclude that G80 cant run DX10.1.

Well think this example: Remember when the good old ATI 9700 PRO was released? It was the first DX9 card! Well it supported up to DX 9.0b by hardware. The third revision of DX9 is the current DX9.0c. So 9700 couldn't support that but guess what? The first cards that had hardware support for DX9.0c was the nVidia 6 series but that was a good two years after 9700!
Based on that, no i don't think that r600 will support something more then 8800. In fact i don't believe that DX10.x will come out any soon. Imo, this MIGHT happen in q3~4 2008. If anyone knows something more specific ok but i base what i say in past experiences and as we know history tends to repeat itself! :wink:

ATi doesn't care about what you think or don't think. They said that the hardware of their R600 will have support for Dx10.1 so that means that their hardware will have that support even if you think it won't.

What i say is based in real facts. As i said i might be wrong and accept correction. Your attitude isn't very polite though. :roll:
I can't judge that but you are new around so make sure to keep a good name. Btw do you have any official ati announcement that supports your claims of DX10.1 support? If you do, you can post a link so all of us can get informed.
I hope you can keep this in a polite level and respect our community.

heh, that's funny, I'd like you to show me what this dx10.1 is, I think everyone here would like to know that ati has something up their sleeve that isn't even heard of...

And in case you didn't know, the 8800gtx has more pipelines than the r600 does, so in case you thought that ati is going to win by introducing unheard of things such as 300pipelines, their not, they will pull off a win due to the fact the xbox360 runs off an ati dx10 card and they already have some experience with dx10 and have had it and are perfecting what they have right now. They will have the superior core (I hope, amd really needs the money) and that is how they will bring in their dough, and they do care about what the public think. If they didn't, they would have simply released some crap with their name on it ***cough***netburst*** and expect people to buy it

As I read all this I couldn't help but hope he does pull some link out of his a**... would make me feel even better about waiting for R600

me too, but I'm confident ati has something up their sleeve, otherwise we would have seen it earlier

you also forgot the fact that the R600 as suposedly 64 4 way shaders. Ie complex shaders for 4 operations, while the 8800 has only simple shaders.

Reply to tamalero

This is what I'm saying, ati has dealt with dx10 before and knows what they're doing and will be able to release the better card from their experience with the 360

You should wait until you have total comprehension of the post you are quoting before you shoot your mouth off like a jackass.

LOL... I responded with a link and some info... a smar @ss remark and a tubgirl image... and it got censured so... now you know that there was info that I'm not going to post again (you can look it up yourself) and that moderator's hands are very light fingered.

You are sick.

Do you even know what ''simple'' pipelines are?!

Taco didn't say that the DX10.1 support comes from the pipelines number, he said that the pipelines are a speed factor! Number of pixel shaders no matter the type can't win alone. 1800Xt and X850 xt have the same pixel shader number. Maybe they perform the same? Do you know at what clock the ATI's shaders will operate?
Also do you know the number, if any, of it's geometry shaders?
How about it's memory interface?
You know only to embarrass yourself and insult this community.
Do you know that around here there are people under 18?
You should be banned for your behavior.
I liked the link you posted. It was very accessible, well informed and above all from a trusted source.

Btw you didn't have to link the picture of your last birthday to convince us!

Obviously you don't understand what the meaning of "sarcasm" is. I do have info about it but I'm no longer posting links so... there's something called "Google" that will help you find info about R600 and it's draft 10.1 unlocking abilities.

Edit: yes... I can be an @ss sometimes...

You are a lier too!
You called taco names and the valuable info you say was just a handwrited text like " the ATI will have support for DX10.1 when Microsoft release it in Q2". It had no link and unknown origin!
I was fast enough to read your original post so i give my congratulations to the moderator for it's fast response and drastic action. I didn't know they are stand by and i am really happy that no one can come around here and do what he likes.

Reply to MikeGR7

No... actually a lier no... when I was editing the post to add the link... it disappeared. Also being gay is nothing bad. Is it? So I wouldn't call that being "calling names" unless you're a fascist and think that being different/gay is a bad thing. And FYI: gay = cheery, bright and pleasant. Is that really a bad thing?

Either way... as I mentioned before... use Google and you'll get the info. Google is your friend.

Reply to heffeque

I can't tell who is disagreeing with who anymore... and I still don't see any reputable links indicating where this "r600 supports directx10.1" mojo is coming from

Reply to LAN_deRf_HA

"you also forgot the fact that the R600 as suposedly 64 4 way shaders. Ie complex shaders for 4 operations, while the 8800 has only simple shaders."

So the R600 has 64 shaders which can perform 4 operations
And the 8800GTX has 128 shaders which can perform 2 operations

Isnt it the same so far?

Now do not forget their clock speed:
I dont know about the R600 but I am guessing something like 675Mhz
And the 8800GTX 1350Mhz

So you see, the 8800 has better specs

Reply to zerobeta

I'd like to see those dx10.1 unlocking capabilities, and just to let you know, those sites are fake, I just googled it for you lazy ass, and I will telll you right now not one is ligit. Once you find me some ligit information, then I'll consider trusting you, until then won't have any friends and will be flamed down by plenty of people here, I can guarantee you that


And to the person that said the r600 has better specs, you have no idea of what you speak of when saying this. In case you need to be learned, the 8800gtx runs at 550mhz core and 1350mhz ram, considering the second revision of he r600 will have gddr4 memory and will be running above the 20000mhz ram the oc'd gtx's have, then you can't say it looses in clock speed. But in case you did not know, clock speed means nothing any more, its all about the architecture and core of the gpu, that and combined with the amount of pipelines. Since the r600 has 64 unified 4 way pipelines, it's not really a fair comparison to the gtx's 128 regular unified pipelines, but those are major things that will affect the performance. Then in the very end, clockspeed will make somewhat difference in the same way they do in conroes, but you're failing to realize the actual details of what affect the performance of things, the days of when clockspeed mattered was back in the days of p4's and the original netburst and presler cores where intel managed to get a stock dual core up to 3.73ghz, but it still lost to amd's 2.8ghz fx-62. All about the architecture.

the amount of complete crap being spoken of in this thread is unreal. could people please look at other r600 threads or use goole before posting.

the quote above is an example of this. mikeGR7. do you even understand what is mean by a unified shader? seriously, the name gives it away i would think.

Reply to strangestranger

go easy on mike, and they actually are geometric shaders though, the regular ones are linear in case you didn't know

Reply to I_Love_Tacos

this isn't flaming btw but thought i would also say it is the shaders in the 8800 that run at 1350mhz not the ram

Quote :

the shader core has its own independent clock generator. GeForce 8800GTX runs at 1,350 GHz and the 8800GTS' clock speed is 1,200 GHz.

Reply to strangestranger

whoops, my bad, confused ram and shader clocks, ram is 1800mhz effective. But still, it's the architecture that matters and how well designed the unified shaders are is what will effect the performance the most, because with the proper cooling, you can simply oc the clocks to match the 8800gtx's if it ends up higher in a lot of catergories

Reply to I_Love_Tacos

hmm, i have heard ATI are limiting how well you can overclock the card are they not. i may be wrong but i have heard some of the newer cards are more restricted. still, if there is one thing we have learned over the years ghz, mhz or hell, just hz do not matter as much as they once did.

Reply to strangestranger

That's what I'm saying, a few years ago (about 4 before amd64 technology was out with the k8 architecture), amd and intel were competing in clockspeed to see who could get the most ghz. Intel managed to achieve 3.73ghz on a p4, amd decided to try a different route with the ht based arch instead of fsb (which intel has decided to implement with a different name in 2 yeas-csi[common source interface or something like that]) and was able outperform intel processors with extreme clockspeeds with things that were from 1.8ghz to 2.4ghz. Later on they decided to push their limits and test out their arch more and released the fx 55 and 57, but that's besides the point. It's been a while now since clockspeed really meant much

Reply to I_Love_Tacos

OK, WTF is the point of this thread now?
A very similar thread started at [H] with better results;
http://www.hardforum.com/showthread.php?p=1030583692

The n00b FAQfest is getting really annoying again. :roll:

The R600 being DX10.1 compliant has been a long standing rumour, ATi doesn't confirm/deny it, which is normal for them, especially since if they knew the delays in prod in Nov, they wouldn't tip their hand knowing it just give nV more info for their refreshes. Some people may remeber the old rumours (partially spawned from EB's article IMO);
http://www.tweaktown.com/news/6703 [...] index.html

As for DX10.1 itself, get yourselves edjucated before posting;
http://www.elitebastards.com/cms/i [...] &Itemid=29
http://download.microsoft.com/down [...] 3_WH06.ppt

The big difference that they are going to address is not multi-core VPUs, but the change in AA functionality and performance improvements. Check slide 30-31;
http://download.microsoft.com/down [...] 2_WH06.ppt

And OMFG, they're already talkig about DX10.2, whatever will we do!

It's not that important, like every previous generation, by the time anyone exploits the new version well enough to make a difference, there will be better/cheaper harware out there to do it.

Regardless of whether or not the R600 does truely support all of D3D10.1 features, it's unlikely to matter anytime soon. The G80 definitely currently falls slightly short of all the specs, but I doubt it will matter more than theoretically. What will matter most is current performance in games/apps. Just like the GF6600 'supported' SM3.0, but the X800XT clobbered it in gaming. If the top R600 only performs as well as the GF8800GTS, no one will care about future cube-mapping support unless they are keeping the card for 4 years, or are developers who need the features and not performance.

No, the G80 is single operation dual issue, the R600 is said to be Vec4 and dual issue. So that would be 2:1, but the question is whether that will be a big difference if there are simple functions. Also the granularity of the R600 may be further reduced/improved over previous generations to improve branching and GPGPU performance, whereas the GF8800 caught up to the X8/X1K series.
It's a theoretical benefit with likely limited early exposure, just like the X1900 3:1 shader difference in the X1800.

Your guess is well below the current writings of 800+, and no one knows for sure if all parts are synchronous like previous designs, or asynchronous like the GF8800.

Quote :

Whatever. :roll:

Commenting on 'better specs' when you obviously don't know the specs one way or the other is just a ridiculous exercise in fanboism.

If anyone is truely concerned, then wait for the launch of the R600, but I doubt it'll matter much for the time being, likely just another checkbox feature at best until 2008.

Oh, BTW, I can guarantee it's not fully DX10.2 capable, so what now? Wait 'til the R680/700 & G90?

Yeah that has tended to be the case with cards coming out and taking a while to get good OCs after some updating of the tools. Also seems that alot are needing Vmod to get the extra juice too.

There was some talk however that the top end cards would be left alone as they have been, and only the crippled and mid-range will have slight barriers put up to protect marketing categories, similar to the way that CPUs are done nowadays with the high end being unlocked.

Reply to TheGreatGrapeApe

possibly, but I got my cheap am2 x2 4000 to 3ghz on a crappy 9500, and most 939's couldn't touch 2.8ghz without better cooling. It's possible am2 didn't have as much barriers, or amd did a better job on the core, but I know that even the fx's have trouble once they hit 3.2ghz, so I'm content and really don't know if there's a barrier on mine or not due to the architecture

Reply to I_Love_Tacos

Well I'm talking about same generation, not comparing the P4 to C2D or AM64 v AM2.

They usually leave the high end open, whether that matters compared to future products is another story completely.
