Official HD 2900 Discussion Thread

[Kasparz]

I know, I saw it. I'm still guessing that's the volt modded extreme cooling section of the review, as vr-zone generally has one for their reviews.

I'm still hoping that R600 have software voltage adjustment as R520/R580.

That´s only why i love ati

From the screenshots from techPowerUp regarding the 2900XT on HIS.


Why in the second screenshot does it have "Crossfire cable x 1" in cable/adaptor bundled?

Does this mean like the cable dongle thing or a bridge?

dongle has been long gone, its the bridge.

Will this card be faster the two 8800gts 640 in sli?

No. If the 2900XT is on par with a 8800GTX, 2x 8800GTS's can beat a 8800GTX.

From what I've heard though, there will be insane headroom on this cards, it shouldn't be a bad buy at all.

As of now, it looks like the following price wise:

$149< HD 2400 Series
$149-$199 - HD 2600 PRO (June-July)
$199-$249 - HD 2600 XT (Three Versions - 256MB GDDR3, 512MB GDDR3, 512MB GDDR4) (June-July)
$249-$299 - HD 2900 PRO (Q3)
$299-$349 - HD 2900 XL (June-July)
$399-$449 - HD 2900 XT (Two Versions: 512MB GDDR3, 1GB GDDR4) (May)
$549-$599 - HD 2900 XTX (Might be more) (May-June)

Approximate...

so there really is a 1GB version being released on in May as well? I thought the 1GB GDDR4 was exclusive to the XTX line and an XT version with 1GB of ram would not surface to reality. I guess another 6 days will tell.

[madcho]

i prefer wait for R650, R600 is great but my R580 Too

The 1Gig version can be considered nearly vapor ware at this point because we won't see it in our systems unless you go through like dell, hp, etc. As well the 1Gig version which we thought was XTX was renamed to just a XT version currently. If there really isn't going to be a refresh of this product that means when the 65nm core R650 comes out they can still use the XTX name still for that core with the higher clocks.

I thought it was OEM, not retail.

[cantankerous]

makes sense guys, I heard this too but thought perhaps things could have changed... yet again. I will not be looking out for a 1GB version it seems afterall.

[KTE]

Totally forget about the idea of an XTX for now.

It's no where to be seen for us. Maybe in the future, but there's no official confirmation of that yet either.

However the 512MB XT will release soon. And it scales very well, gaming performance/quality is supposed to be better than number applications.

Here's one to buy, pre-order for 357 Euros: http://www.icomputers.nl//articledetail.aspx?A_ID=10878

Quality.

You know what I'm thinking, what might be a crucial point in deciding between the 8800GTS and 2900XT.

PSU.

I have a Corsair 520w, good enough for 8800GTS in SLI, but I don't think it is good enough for the 2900XT in Crossfire.

Buy a 8800GTS now, if Crysis comes, I can upgrade to SLI, but if I buy the 2900XT, then I'm stuck. If performance is close to each other, I'm buying a 8800GTS.

Makes sense doesn't it? 225w for the XT is a no no, too high, single card yes, but Crossfire....phew.

You might already have an issue if you OC CPU etc too. Check how many Amps your PSU can do on the 12V rail(s).

AMD recommends a 750W PSU for a system with a single 2900XT.

[aMp]

We're talking about $350-450 graphics cards and you're worried about a $125 PSU upgrade?

[Shintai]

Then he could just aswell buy a 8800GTX instead

That's for Crossfire IIRC, and it was originally posted by Fudzilla, dunno if all that is correct, anyway, my PSU is powerful enough for 2x8800GTS both cpu and cards overclocked . Many people have this setup. (It's the Corsair HX520w)

I have no hope of running Crossfire with that if a single card draws 225w.

[DilTech]

If you can buy the competitors product without spending the $125 and not losing $125 in performance, then why spend the extra $125 in the first place? The extra $125 is enough to buy the GTX over the XT or GTS.

Exactly.

Not sure if this was allready posted!

HD 2900 thermal numbers out, 225W

Three kings including the XL

ATI will introduce three Radeon HD 2900 cards on the 14th of May. According to a document we've seen the most powerful one is called the Radeon HD 2900 XT 1024MB DDR4. Its TDP, thermal design power of the GPU, is an astonishing 180 Watts, while the whole board dissipates 225 Watts.

The second card is the Radeon HD 2900 XT 512 MB GDDR3 and its GPU's TDP is 160W due to slightly lower clock speed and the whole board again dissipates 225 Watts.

The third and final card is the Radeon HD 2900 XL, a cheaper version of the marchitecture with 512 MB GDDR3 and its GPU will dissipate 130 Watts, while the board will dissipate 205 Watts. We believe that the power components on the card gets really hot, 82 degrees C on the outside of the cooler is what we've already seen.

Yes, and how many W can the standard PSU do on the 12V rails?
About 25&#37; is dedicated for 3.3 and 5V, CPUs today are more or less using only 12V too. So a 225W GPU and say a 100-150W OCed CPU, HD(s) etc quickly count up high.

R600 minimal requirements pictured

Update: Works with a good 400-500W as well

As some of our readers actually didn't believe that their bellowed R600XT might need 750W or more here is some proof. AMD clearly states you need a 750W or better power supply for this hot beast. You also need an Athlon or Pentium 4 of better CPU, 512MB to work and 1024MB for optimal performance or more. You can read the original part here.

The card supports Windows XP, 2000 and Vista both 32 and 64 bit one. We still have hope that the card might work with a good 500W but this is what AMD recommends. Well, it's all here.

Update: We still stay behind the picture we posted but several sources close to AMD, partners and retailers who had the card confirmed that a single Radeon HD 2900 XT works with a good quality 450 - 500W PSU as well. One of the sources confirmed the slide we posted but said that this is actually a Crossfire Radeon HD 2900XT with Quad core system requirement. Some of our friends will test the card for us and we will let you know if it works with 500W. Stay tuned. Gibbo from Overclockers had tested his card and he said it will run with 400-500W PSU and you can read it here.

[Shintai]

Yes, I can run it on that too. Running at stock and a stock speed C2D. Put in a C2Q/X2 and it quickly gets more problematic. And forget any OC.

[mascaras]

OCZ gamexstream 600wts PSU no problem at all overcloking E6600 and x2900xt 512mb


Btw: with 8.374 driver on windows XP in 3dmark 2006 with card default and e6400 @ 3ghz the score is very good

with Vista the driver still not so good , less ~1000 marks and also less FPS (some games -60 FPS )

[biohead]

Of course it won't need a 750W PSU. Anyone could've written that document.
