R600 too hot to handle

[AthlonXP1800]

VR-Zone got interesting info about R600, they had seen the card, it about as long as Geforce 8800 GTX length, it used massive dual slot 4 heatpipes cooler large than the card PCB to cool off the 300W beast. :eek:

http://www.vr-zone.com/index.php?i=4181

We know the Geforce 8800 GTX power requirement is 450W and 800W for SLi so I got a good idea what power requirement R600 will need. It require about 600W for a single card and 950W for Crossfire.

I wonder why its suffering from poor yields. I think we may have an R520 situation all over again. In that case, Ati can kiss the next generation goodbye.

[Daydre@m]

Yeah your right . Poor yield = Add another 6 months .....

It might be another R520 but I hope not , ATI is kind of making improvement now with internal crossfire as seen on X1950 pro, so I hope they do improve and get the product to maket and finally make a hard launch .

(wack)


1) their is no such thing as a 300w gpu. You actully think that a 80nm node packing 500+ trans will rate 300w by its self? no no.

2) the 450w power requirement for G80 is assuming under a fully loaded system, G80 takes roughly 150w-180w by it self.

Don't count on it. My sources say other wise.

Sounds like the 5800 Ultra all over again :D

I am not VR-Zone, well you never know so it not just the R600 chip, it the whole card need 300W probably because of very complex 512bit bus and the reason it cool with very large 4 heatpipes cooler bigger than R600 board.

Yes here are such as a 300W GPU.

DirectX 10 GPUs to Consume up to 300W (http://www.anandtech.com/tradeshows/showdoc.aspx?i=2770)

ATI and NVIDIA have been briefing power supply manufacturers in Taiwan recently about what to expect for next year’s R600 and G80 GPUs. Both GPUs will be introduced in late 2006 or early 2007, and while we don’t know the specifications of the new cores we do know that they will be extremely power hungry. The new GPUs will range in power consumption from 130W up to 300W per card. ATI and NVIDIA won't confirm or deny our findings and we are receiving conflicting information as to the exact specifications of these new GPUs, but the one thing is for sure is that the power requirements are steep.

Power supply makers are being briefed now in order to make sure that the power supplies they are shipping by the end of this year are up to par with the high end GPU requirements for late 2006/early 2007. You will see both higher wattage PSUs (1000 - 1200W) as well as secondary units specifically for graphics cards. One configuration we’ve seen is a standard PSU mounted in your case for your motherboard, CPU and drives, running alongside a secondary PSU installed in a 5.25” drive bay. The secondary PSU would then be used to power your graphics cards.

no.

[Fotis]

Vr-zone also said that R520 would have 32 pipelines.:captnkill:

[SH64]

I dont believe the power req would be that high.
& if those specs are any indication , i'd say the R600 is quite a beast!

I really don't think the power requirements are as high as they say they are. I'm still not sure how they can claim 450W for a single card setup then another 350W just to add in another card. Unless it causes a huge leak somewhere I can't imagine slapping in another card to add that much.

I actually have a Q for you SH64, does your 750W thermaltake handle the quad cards fine? It would seem to me if a 750W PSU can handle 4 GPU's + a full system, that a single card would need more power than a 2 last gen cards combined.

If memory serves me right, they did lower the requirements for the 6800's after they throughly tested it and didn't have any problems. I'm guessing they are just erroring on the side of caution.

[stevemedes]

Amazing speculation going on in this thread. Everyones set on the G80s and are trenching in their anti R600 stance before we've ever seen an *official* picture of either card.

[Zelda_fan]

no.

Don't take AthlonXP seriously. No one else does.

Well, I'm not one to past judgment, but he dose sound loss.:p

Too hot to handle
Too cold to hold
They're called the Ghostbusters
And they're in control.

Everyone round here has sources these days. When do you sources say its going to be released?

Yep It does handle the quad setup just nicely .. actually even my older Tt680W PSU was fine , but i got this one just to be more comfy & make sure i'm above min reqs.

You ahve not changed an inch over the last three years... :D

[Belarnion]

Let's make a few calculations based on earlier cards here...

500M transistors * 700MHz * 80nm (1.3V) = about 175W
500M transistors * 700MHz * 80nm (1.2V) = about 150W
500M transistors * 700MHz * 80nm (1.1V (A bit unlikely)) = about 125W

500M transistors running at 700MHz using 80nm and in the area of 1.25V is actually quiet possible. (140-160W)
X1950XTX uses about 120W, 90nm and 1.4V.
7950 GX2 uses about 140W, 90nm and 1.25V.
My two V-modded and oc-ed 7900GT's use about 130W each with 1.5V.


If Inquirer and maybe vrzone is correct with everything they say, the poor 80nm chip has to run at 1.7V(!!) to produce 300W of heat.
That is very, very unlikely, considering the highest voltage used for the current generation of 90nm GPU's is in the order of 1.45V.
Some of the rumored specs are very wrong. I think it's the power requirements.

[Dazz]

I am sure if it was 1.7v for 80nm then there would be electormigration which will kill the core so i would say it is over the top.

[Belarnion]

Yes. Even 1.5V would've killed it. 1.25V or thereabout is most likely. Maybe the 300W power draw was really for crossfire? If it is so, everything makes perfectly sense.
