Well Well looks like allot got a "source" theese days :p Include me there now.
Just got a hold of some info regardring the r520 speed from a card maker.
The X1800XL will be a little slower then the 7800GT
The X1800XT will be a little faster then the 7800GT
Yep thats it. Take it as you will. I know it dont seem like mutch info but it is from a card maker.
Anny way, we will all know soon. But i trust him on this one.

He also said that the 7800GTX would be in no danger from losing the performance crown.
I would like to state again that feel free to not believe me. Just keep it flame free. But if i was a betting man i would bet on this info :o
Hmm, that's surprising. I guess we'll know for sure soon.
ya ... hmmm i think this sounds about right .... i dont think we will see much performance from the r520 over the gtx.... this would go along with the info about ati getting out the r580 .....

Well we can look forward to next week then hehe :) But i actually feel a bit better now i almost just got a 7800GTX :)
All i want now is a gtx with 512mb of ram.
If ATI is to be believed the Radeon X1800XT consistently outperforms the GeForce 7800GTX in all games, sometimes by as much as 80%
Sander Sassen has written a new article about R5xx.

No X1800XT until November, but the XL will be available next week.
And i'll believe the 80% when i see it. :o

Well i belive my source on this one.
"the x1800xt will have just a bit more performance than the gt" yep thats a quote. Ill take the word from the card maker on this one.

note GT, NOT GTX.
I love dual slot dustbusters they are great :D

Bah, I knew it. $500 and its slower than a GTX?? Who in their right mind would buy it?? Definetely a failure in my books. This is the "5800 Ultra" of 2005.

Man it's like we're in the twilight zone. Nvidia besting ATI with a slow single slot card 6 months early...
I'm going to go check my lottery ticket. I might have just won.

Anandtech was hinting today that it can do MSAA with FP render targets. If that's true, then it might prove to be a huge feather in its cap. Yeah, it might be a few frames slower than the GTX, but my understanding is that "true" HDR and MSAA looks way better than what Valve has done with Source.
I have personally not experienced Valve's HDR implementation, but from the screenshots and videos and from comments from people who have played it, it does seem to look a little tacky. Admittedly, I don't know if that is because of Valve's approximation. One thing is for sure, though -- if the R520 can do FP16 + MSAA, I'll bet a year's salary that Valve has already put that codepath into Source.
My source says that ati fans will be very happy and pleased.
Quote me on that. ;)

Have you totally forgotten that the 5800 Ultra sucked in more than (the days crop of games) performance? The 5800 had the ability to wake the dead at full fan speed and the NV30 architecture was totally useless in PS2.0 games. I really doubt that the X1800XT will sufferer from these issues. Your also very quick to believe this. Plus the current GTX only has 256mb of memory vs. 512mb on the XT.
The HSF is identicle to the X850XT's which is very quiet and does a good job of keeping the card cool. Its funny, most of the people whining about this cooler are the ones who bought NV Silencers for their 6 series cards. :rolleyes:
I'm not gonna flame ya PeterJensen, but I sure as hell don't believe you. :D

Yes, I think we all know you're excited about the XT having 512M by now.
Your also very quick to believe this.
...and you quickly dismissing this is different how?
...and you quickly dismissing this is different how?
Because 90% of the time these "rumors" are wrong.

Intresting,
So you are sayin, that r5xx can do HDR+MSAA.
where did i read, but some nv guy mentioned in an interview, that it can't be done, not in this gen of cards atleast.
anyways, i would be glad, if r5xx could do it.

Well, i m sure jakup only meant PERFORMANCE by that post. im sure neither ati nor nv will design a cooler that loud... not now and not in the near future.
Its funny, most of the people whining about this cooler are the ones who bought NV Silencers for their 6 series cards.
AND your point is...
AFAIK, majority of the people on this board own GF6 cards. And, people want to O/C their cards without having HEAT troubles have bought nv5 coolers.
Same implies to people on a board having majority of ati-card owners.
Well i kind of believe peterjenson's source. Besides 3dm'05 and hl2, i dont see r5xx leading the g70-gtx.
Plus the current GTX only has 256mb of memory vs. 512mb on the XT.
I dont think this will make the r5xx perform faster than g7x. sure it will be tad smoother compared to g70 in BF2.

I'm not saying anything!!! :D
Here's the Anandtech quote:
One of the easiest ways to implement HDR from scratch is to use a floating point format with all art assets designed around HDR. Unfortunately, current hardware isn't able to handle full floating point data as fast as other methods, and no hardware (that is currently out) can allow MSAA to run on a floating point render target.
Some guy at Beyond3D pointed this out first. Looks like Anandtech is toying with their readers :). Note, however, that there are two points mentioned above:
(1). Current h/w isn't able to handle FP data fast enough
(2). No "current" h/w is able to render to an FP render target with MSAA
My graphics knowledge is very limited, so take my words with a truckload of salt. The Nvidia guy you're talking about is probably David Kirk and I believe the point he was making was similar to (1) above. He was claiming that you would need huge memory bandwidths to support HDR assets. However, that does not explain why NV hardware cannot support (2). I think the R520 may have support for AA-FP render targets, and thanks to its 1.5Ghz memory bus speed, it might mitigate (1) and thus be able to support full HDR+MSAA on small or moderate sized maps.
if i understand it right, isnt AA applied at the final stage of rendering ... and isnt HDR also a final stage renderer .... so how do you do two final stage renderers ... unless you apply AA during the shader step.... thats the only was i could see it working...

HDR isn't a final stage effect - you're probably confusing it with post-processing for bloom etc. True HDR is done throughout the entire pipeline from start to finish.
To the OP: I don't know what to make of your buddies comments when ATi is claiming the XT is 90% faster than the GTX in F.E.A.R - http://www.theinquirer.net/?article=26617
(2). No "current" h/w is able to render to an FP render target.
:confused:
Can't the 7000/6000 series NVIDIA GPUs render to an FP render target?
You just can't have MSAA and FP render target with 6000/7000 series NVIDIA hardware is how I am reading all that.
We all on the same page or did I miss something?

Thing is who cares if it it can do it? If it is slower then GTX you wouldn't get any performance with HDR + AA anyway.

Yes, yes, you're absolutely right, it's MSAA + FP render targets that messes things up. I edited my post. Sorry! :o
