HD 2900 thermal numbers out, 225WQuote:

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?Quote:

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.

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.
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 )

Of course it won't need a 750W PSU. Anyone could've written that document.
eek. That Coolaler link is showing the card running off of HYNIX ram. Is this going to be a problem performance wise? I thought the card was using tried and true Samsung.
It looks as if they removed the second fan connector as well.
While I can't say ALL the MSI graphics cards use hynnix, the ones that I have had in the past have all used hynnix. Its just what they choose to use, and does not affect other venders.Quote:

How can you overclock the 2900XT while using the GameXsteam, which doesn't have the required (for overclocking) 8-pin plug?Quote:

Ah, that sounds nice. Do you know what plugs the adapter uses? Molex?Quote:

Well the 8 pin is supposed to be 150W, so 2 x 75w PCie 6 pin plugs. 3 in total to run the card.Quote:

As far as rating of plugs, then 2 x molex is used for 1 x 6 pin PCIe.Quote:

It does add up to 225W, but they don't run right to the edge and use a tolerance.. The cards TDP is 225W.Quote:

So to overclock it needs the extra capacity of the 8 pin connector. 2x6 will run at stock.
Isn't TDP for AMD a maximum value and for Intel an average value?
No not the average, Intels are a bit short of maximum, maybe 10%. Neither are the maximum wattage a chip/card will draw in our world because we overclock/overvolt, taking them beyond TDP.Quote:

This means that TDP, as defined by AMD, is measured at the maximum current the CPU can draw, at the default voltage, under the worst-case temperature conditions. This is the maximum power that the CPU can possibly dissipate. Intel, however, has a different definition.
Intel’s TDP is actually lower than the maximum power dissipation of the processor (and as you’ll see later, it can be significantly lower). This is in stark contrast to AMD’s TDP numbers, which are higher than the respective processor’s maximum power dissipation.
Thats not entirely true.Quote:
