ATI Radeon HD 2900 XT: Calling a Spade a Spade

Sapphire's HD 2900 XT
We wanted to include some noise and overclocking performance here as well, but we don't like testing overclocking with reference or engineering samples, as they don't always reflect what we'll see on store shelves. We've got a better chance of seeing real world characteristics in boards from specific vendors.
Sapphire went to a lot of trouble to get us a board, but due to a shipping mishap we were unable to test it in time for this review. Later this week we'll take a follow-up look at R600 including overclocking and Vista performance to fill in the gaps we weren't able to cover here. We really appreciate Sapphire's efforts to help us get this coverage into our launch article, but we'll have to wait on this data.
From what we see with our engineering samples, core clock speeds of 850MHz+ are possible, but whether this will have a large impact on performance remains to be seen. We will also be working hard on getting a roundup of retail hardware out as soon as possible including overclocking, power, heat, noise, and all the other fun stuff that makes a big difference in retail hardware.
And we won't just see a bunch of cookie cutter retail designs out there either. Sapphire and others will have custom cooled and factory overclocked boards on their way as soon as possible. Even though AMD won't have the highest performing part on the market, or even a pretender to the throne, we can see a great competitor to the 8800 GTS emerge if prices and clock speeds from retail partners hit the mark.

What is the latest on the so-called Dragonhead 2 project (aka, HD 2900 XTX)? I heard it was just for OEMs at first...anyone know if the project is still going and how the part is benchmarking with newest drivers?teainthesahara - Monday, May 21, 2007 - link
After this failure of the R600 and likely overrated(and probably late) Barcelona/Agena processors I think that Intel will finally bury AMD. Paul Ottelini is rubbing his hands with glee at the moment and rightfully so. AMD now stands for mediocrity.Oh dear what a fall from grace.... To be honest Nvidia don't have any real competition on the DX10 front at any price points.I cannot see AMD processors besting Intel's Core 2 Quad lineup in the future especially when 45nm and 32 nm become the norm and they don't have a chance in hell of beating Nvidia. Intel and Nvidia are turning the screws on Hector Ruiz.Shame AMD brought down such a great company like ATI.DerekWilson - Thursday, May 24, 2007 - link
To be fair, we really don't have any clue how these cards compete on the DX10 front as there are no final, real DX10 games on the market to test.We will try really hard to get a good idea of what DX10 will look like on the HD 2000 series and the GeForce 8 Series using game demos, pre-release code, and SDK samples. It won't be a real reflection of what users will experience, but we will certainly hope to get a glimpse at performance.
It is fair to say that NVIDIA bests AMD in current game performance. But really there are so many possibilities with DX10 that we can't call it yet.

From the last posting of results for the GTS 320MB round-uphttp://www.anandtech.com/video/showdoc.aspx?i=2953...">Prey @ AnandTech - 8800GTS320
we see that the 2900XT review chart pushes the nVidia cards down about 15% across the board.

The only difference in systems is software drivers as the cpu / mobo / mem are the same.
Does this mean ATI should be getting a BIGGER THRASHING BEAT-DOWN than the reviewer is stating?
400$ ATI 2900XT performing as good as a 300$ nVidia 8800 GTS 320MB?
Its 100$ short and 6 months late along with 100W of extra fuel.
This is not your uncle's 9700 Pro...

We switched Prey demos -- I updated our benchmark.Both numbers are accurate for the tests I ran at the time.
Our current timedemo is more stressful and thus we see lower scores with this test.

The prices listed in this article are way off.Currently, 8800GTS 640MB retails for $350-380, $400+ for OC or special versions. 2900XT retails for $430+. In the article, both are listed as $400, and as such the card is given a decent review in the conclusion.
Realistically, this card provides slightly inferior performance to the 8800GTS 640MB at a considerably higher price point -- $80-$100 more than the 8800GTS. I mean, it's not like the 8800Ultra, but for the most part this card has little use outside of AMD and/or ATI fanboys. I'd love for this card to do better as AMD needs to be competing with Nvidia and Intel right now, but I just can't see how this is even worth looking at, given current prices.

really, this article focuses on architechture more than product, and we went with MSRP prices...we will absolutly look closer at price and price/performance when we review retail products.

As I recalled, the Radeon HD 2900 only has DVI ports, but nowhere in DVI documentation specifies it can carry audio signals. Unless the card comes with adapter that accepts audio input, it seems the audio portion of R600 is rendered useless.DerekWilson - Wednesday, May 16, 2007 - link
the card does come with an adapter of sorts, but the audio input is from the dvi port.you can't use a standard DVI to HDMI converter for this task.
when using AMD's HDMI converter the data sent out over the DVI port does not follow the DVI specification.
the bottom line is that the DVI port is just a physical connector carrying data. i could take a DVI port and solder it to a stereo and use it to carry 5.1 audio if I wanted to ... wouldn't be very useful, but I could do it :-)
While connected to a DVI device, the card operates the port according to the DVI specification. When connected to an HDMI device through the special converter (which is not technically "dvi to hdmi" -- it's amd proprietry to hdmi), the card sends out data that follows the HDMI spec.
you can look at it another way -- when the HDMI converter is connected, just think of the dvi port as an internal connector between an I/O port and the TMDS + audio device.

I was at an AMD movie night last night where they discussed the technical details of the HD 2900 XT and also showed the Ruby Whiteout DX10 Demo rendered using the card. It looked amazing and I had high hopes until I checked out the benchmark scores. They're going to need more than free food and popcorn to convince me to buy an obsolete card.However there is room for improvement of course. Driver updates, DX10 and whatnot. The main thing for me personally will be driver updates, I will be interested to see how well the card improves over time while I save my pennies for my next new machine.
Everyone keeps saying "DX10 performance will be better, yadda yadda" but I also want to be able to play the games I have now and older games without having to rely on DX10 games to give me better performance. Nothing like totally underperforming in DX9 games and then only being equal or slightly better in DX10 games compared to the competition. I would rather have a decent performer all-round. Even saying that we don't even know for sure if DX10 games are even going to bring any performance increases of the competition, it's all speculation right now and that's all we can do, speculate.
Shaun.
