Official HD 2900 Discussion Thread

[fornowagain]

i fugure u know future graphics card might need 2 x 8 pin PCI-E .. and that thermaltake 1200 has 3 of em , and 3 x 6 pin PCI-E, so it can power 2 x GPUs each needs 2 x 8pin PCI-E ...

Back it up a bit.

1. They're moving graphics to 65nm, so power will go down.

2. If a card needs 2x8 and you crossfire that's 4, you still don't have enough without adapters.

3. I would think the reason it has three of each is to power 3 current GPU. One maybe used for physics? Like the RD600 motherboard for example.

4. PCIe 2.0 will be out soon and the slot will be 150W. By the time any cards with 2x8 connectors appear (if ever), the new PCIe V2 motherboards will be out and have lots more power.

5. If a card needs 2x8. Quad cpu with crossfire will still be 725W/60A. Maybe 8 core crossfire needs a 1200W PSU. Good luck with that!!

Buy what you need, when you need it. The specs change to much to guess that far ahead. Personally I'll be making/buying 6 to 8 pin adapters. What's the combined 12v output for your 750W Thermaltake, 60A? I'd bet that'll be quite happy running 2x2900XT's.

yeah good point ... QX6700 + 8800 GTX SLI dont use more than 550w load ... even Corsair 620W can power that

still the native 8 pin PCI-E is nice , and what i was thinking was to get a PSU that has as many 8 pin PCI-E as possible ( and only those 1000+w PSU has 2+ of em )

and yeah it has 60A , but for adapters i will need to have 4 x ( 2 x molex > 6 pin PCI-E ) > 2 x 8 pin PCI-E + the 2 x native 6 pin PCI-E to power HD2900XTX Crossfire

If you intend to run ur pc at stock...sure...

But if you're ocing at the level of the average xs member ("I needs ma QX @ 3.6 Fashizzle !" :p ) then you'll need at least a 750w pcp&c, zippy, or etasis base silverstone or preferably a 850w if you'll be ocing both cards or if you intend to mod or water cool them.

ROFL, that's good stuff........

You all are forgetting something. In the conference video AMD had about their new products(the video is somewhere around here), when a reporter asked about power usage (loose quote) they said:

"The R600 is the maximum power card we are most likely going to produce. We are aiming for efficiency similarity to that of how CPUs are decreasing power with each generation."

This was the same conference video in which they accidently slipped out the R650 word following R600 release shortly with 1/3 less power requirements.

So putting the R600 xt at a power requirement of 250watts, we can expect the r650 to be around 165watts @ 65nm.

I don't think that we will ever be seeing those killer PSU requirements, and I hope that they do stick to their guns and provide efficient solutions in the future that run faster and suck up less power. The mainstream is to cheap at buying PSU's anyways, much less spending over $100 on one is out of the question to most people.

[theteamaqua]

they better ... i thought 2 x 6 pin PCI-E for a single card was much ... 8800GTX

[b0bd0le]

i apologize for not keeping up with the thread...

but when is the release date for ati's new stuff?

Mark your calendar for May 14. Unless AMD decides to tease us more by announcing on that day "We changed our mind and want to release this with K10 products."

Tease? More like throw a grenade in their pants.

then i'm going completely bezerk...all those info and it's impossible to tell what's true and what's horse-s***t

The short answer is believe nothing but expect anything.

quite dangerous,don't you think...When you expect anything,you're probably in for a BIG disapointment ...

but by expecting anything, wouldn't it be logical to also expect disappointment?

[bloodbanger]

probably you're right again,but on the other hand:A card that's 7 months late SHOULD be anything,except a disappointment...

Umm it isn't 7 months late, not even by a long shot

[Shintai]

Uhm...yes it is....Unless they stepped out of something called competition and gave up.

I'm speaking of launch dates, unless of course you are willing to admit that conroe was about 3 years late

Some news on real-world price


A local dealer/retailer has HD2900XT512 on preorder
And it's just HuF 85 145 - (~$468) with 20% tax - that's $390 w/o tax!
It's lower than the GeF8800GTS640 (~90 000), which has been on sale for half a
year - and it's still preorder, meaning it has a price premium
Not to mention the overpriced/underperforming 8600GTS around HuF 50 000

Wow this thing is going to be dirt cheap for me then when its available through ATI. when the 1900 and 1950 launched they were both $299. I'm hoping to see thing around $250, I have a feeling ATI is desperate though due to all the negative PR lately, so their probably isn't too much Margin attached to this card.

No, more about a year. But then K10 is over a year late too....

For GPUs its alot more changing market and hurts much more with waiting. AMD lost more share in the GPU/IGP market in Q1.

Going by your rationality that being behind in performance is being late, yes Conroe was 3 years behind...

Either way, the R600 is late... How late from their initial plan, no one knows, but it's DEFINITELY late.

[bloodbanger]

i read some info that there are also standard o'c-ed cards due to be released?Any confirmation on that?

A64 didnt beat the P4 right out of the box with a huge margin. It first really manifested with the X2 series.

Also, Unless AMD GPUs got a process advantage over nVidia. Then its still nothing even remotely equal to the A64/P4 moniker.

I hate nVidias sole power with the 829$ Ultra

[b0bd0le]

ok by that same logic, amd's next chip is already a year late

[milkcafe]

8800 Ultra = $799
Two HD 2900XTs in Crossfire = $799

Wait for the pwnage May 14th.

Radeon HD 2900XT needs 750W+

lol..... no.... definitely not gonna be that bad....

look at this thread to see what you can run with a 500w psu....
http://www.xtremesystems.org/forums/...d.php?t=141505

the difference in power consumption between 8800 GTX and Radeon 2900 will not be 250+ W, so... no... you won't need a 750 W PSU for it...
