Introduction By: Sander Sassen Well ATI sure kept us waiting, but it will finally be introduced this month, the R520 architecture, the successor to the X800 family of [color=blue][color=blue]graphics cards[/color][/color] and a contender for the [color=blue][color=blue]3D graphics[/color][/color] throne. But why wait for that introduction when you can have a sneak peek today? Normally we would’ve adhered to ATI’s NDA and published results the moment it expired. However this time around ATI decided to just not bother with us as they made it very clear that we did not make the cut, as we have written some articles about CrossFire, R520 and ATI’s financial situation that were apparently not appreciated. Hence we’ve not been briefed by ATI, nor did we sign an NDA, or have been invited to the launch event, so basically they decided to cut us off. Unfortunately for ATI we have other sources to get detailed information from, for example the board partners that will be manufacturing and selling the majority of these new graphics cards. Obviously because we’re not bound by any NDA or other agreement with ATI we’ve worked hard to get you some benchmark results prior to the launch which is scheduled for the end of this month. To ATI we’d like to comment that it is a two-way street really, we’d like to be briefed about your products and have early access to them, if that requirement is met we will have no issues with signing and adhering to NDAs. By cutting us off however we’ve just been given a new incentive to work harder to break the news when we get a chance, in our usual no holds barred fashion. So what does the R520 architecture bring to the table exactly? For starters it is not the 32-pipeline architecture it has been rumored to be, it is half that, offering just 16-pipelines, which is less than NVIDIA’s G70 architecture that has 24. The R520 architecture will be introduced as the X1800 series, featuring the top-of-the-line Radeon X1800 XT with a 600MHz core clock and 700MHz [color=blue][color=blue]memory[/color][/color] clock, yielding an effective 1400MHz memory clock speed. The 600MHz clockspeed combined with 16-pipelines for the [color=blue][color=blue]graphics processor[/color][/color] will give it a lower fillrate than the [color=blue][color=blue]GeForce[/color][/color] 7800GTX though, although the 7800GTX’ graphics processor runs at just 430MHz. With 512MB GDDR3 memory connected by a 256-bit wide memory bus the X1800 XT boasts more memory than the 7800GTX, but as shown before with 512MB version of the GeForce 6800 Ultra this will usually not help performance much, if at all. The Radeon X1800 XT will ship with a $599 price tag, which is $100 to $150 more than what GeForce 7800GTX graphics cards are currently sold at, not exactly cheap. Other models in the Radeon X1800 series include the X1800 XL clocked at 550MHz core clock and 625MHz memory clock respectively at $499, the X1800 Pro at 500MHz with 256MB of memory running at 500MHz with a $449 price tag and to close the ranks ATI will offer a X1800 LE at 450MHz/450MHz for $349 with just 12-pipelines and 256MB of memory. With the help of a board partner we’ve been able to run the same set of benchmarks we’ve previously run on NVIDIA’s GeForce 7800GT and GTX, although we could only submit our benchmark [color=blue][color=blue]scripts[/color][/color] and testing configuration to them. The numbers you see reflected in the next few pages are therefore provided AS IS, as we have no way to verify them as we don’t physically have a board, they are accurate as far as we can see and in line what we’ve been expecting. So without further ado, let’s take a look at what the R520 architecture is capable of.
Read the rest at to see its benchmarks. http://www.hardwareanalysis.com/content/article/1813/ Its not 32 Pipelines its not even 24 Pipelines, only 16. SLI 6800GT and Ultras do better than the X1800 XT. The 7800GTX owns the X1800 XT.

and you made a new thread why??? nice find though

im dissapointed the best ATI are offering is 16 pipelines i heard 32 the other day, then 24, now 16... great oh well it still looks a nice card :D

well, the 7800GTX seems to be beating it out every time.....especially in SLI mode, i guess we gotta see what crossfire does for it
Agentlaidlaw SLI 6800GT and Ultras do better than the X1800 XT. The 7800GTX owns the X1800 XT.
maybe not owns. one thing is for sure, ATI has let me down, i really dont know what to say. im never going to bow to that 7800, im out of this generation, my care and consern just went out the window. until ATI makes a 24 pipe R5xx core, im out.

Come on! ATI had the chance to totally obliterate the 7800gtx with the x1800xt with 32 pixel pipelines and they drop it to 16:wtf: Eh I am fine with my 6800gt for now. I am not sure if I will ever go back to ATI with them dropping the ball like this...

maybe they think everyone is stupid, and nobody does their homework. ATI thinks "lets just give em something new, it dosen't need to actualy be better. the tards will buy it" up yours ATI:moon:

seriously...WTF are they thinking!!!!!!!!!!!! they have all the smarts to make at least a 24 pipe gpu. WHAT THE FUCK!

I've just found this :
Sander Sassen over at HardwareAnalysis apparently was a little agitated regarding the fact that he is bypassed by ATI and let me quote "ATI decided to just not bother with us as they made it very clear that we did not make the cut, as we have written some articles about CrossFire, R520 and ATI’s financial situation that were apparently not appreciated". That warm feeling towards ATI of his resulted into leaking benchmark results on the ATI's new Radeon x1800 Pro and XT today.
[indent] Sorry guys, can't help you with pics or driver revs and all that, the testing was done in the lab of one of ATI's board partners in Taiwan, and they're not about to disclose who they are, as ATI will certainly want a 'word' with them. Nevertheless my hat's off to them and a big thanks is in order, as they were willing to help me when we came to them for a scoop a few weeks ago, and a scoop it sure was.
[/indent] Sander obviously did not produce the results himself, yet apparently the results come from a board partner in Taiwan. Although the "review" misses out a lot of info it positions the R520 products at the 7800 GT and GTX level. Both give and take a little. I really don't know if we can trust the results published by Sander as you need to test a product in-house and not rely on 3rd party based beta engineerging products.
ATI's (Chris Hook) first reaction to this article was: " Fiction. I don't believe these numbers were ever run on a 520 ".
A second response just came in:
"This is a complete hoax - done with an OC'd X850, we think. Call our partners yourself and ask if they have R520XTs in house. The numbers aren't even close."
Komrad_BI've just found this : http://www.guru3d.com/newsitem.php?id=3069 Hoax?
hopefully, it would be nice, and pull me closer to ATI.
