In addition, as for the same company, as for DirectX 10 GPU of 80nm edition, when it becomes TDP of 1.6 times that of the current model, you say that estimate it did. But as for 1.6 times, selfish estimate of ATI side, really, NVIDIA when the MAX electric power of the G80 board becomes 175W, vis-a-vis the OEM vendor, it is said that it conveyed. This number in the product is a possibility of changing, but G80 is not wrong GeForce 7900 GTX (G71) from as for being the electrical eating.

With increased by 40% transistor count will set max TDP 1.6 times more than current generation:
- ~175W for G80;
- >200W for R600.

What is an R580 using now?

I am curious if my Powerstream 600w is going to be enough for a single R600.

You can get additional PSU just for VGA. It fits in 5" slot

lets hope them numbers are not 100% true and that both of them or one of them pulls a rabit out of their asses and brings a card that slurps less power.

No friggin way, besides I don't have any more space for large bay devices. PA120.3 top mount.

Good thing PSUs are relatively cheap.

You forget that some part of this power consumption is going to MEMORY and R600/G80 will use GDDR4 which will be not so power hungry.
So equation 120*1.6 is wrong, we need to extract only GPU power first.

I think that R600 with GDDR4 ~2.4GHz should consume 160W-180W.:cool:

You forget that we've never seen the effects of a GPU at full load.

Those temps/power levels we're seeing out of the R580 is roughly 60-70% of the overall *full load*, as there's nothing out that uses every transistor on the gpu. Generally a scene is either pixel hungry or vertex hungry. Almost never both.

With unified shaders, the gpu will hit full load, no questions asked. If 120+Watts and 80-90C temps are drawn from a 300+ million transistor chip at 60% load, what's going to happen with 500+ million transistors at 100% load?

That's right, 200+ Watts, as for temps they better have one hell of a nice cooler. Even after a die shrink.

No they will NOT, simply because the backlash from Intel's BTX has proven people will only accept so much

onewingedangel

07-29-2006, 12:12 PM

The backlash against btx was due to the mistaken belief that atx cases and equipment would suddenly become obsolete. btx has established itself nicely in the oem and system integrator trades, and will be making more strides into the enthusiast market over the next few months and years. Graphics heat is actually one area that btx does not really improve on, but with the blower designs that ati use all the heat is dumped out of the case anyway.

I would predict that should these power consumption estimates be accurate, the following revisions'die shrinks/successors of the chips will deal almost exclusively with reducing power consumption until it's back to more acceptable levels, and offer only modest performance improvements.

I wonder if the midrange cards will consume more than 100-120w.

To put some light on topic anyone can tell what power consumption have XBOX360 GPU??
It is 90nm, it is unified shader, but it is only 48 'way' and it is around 30% less sophisticated than upcoming R600.
100% utilisation and 60% utilisation may have for example only 10% difference in power consumption! Why? Because if you use 1 pixel shader from 1 quad power is delivered to 1 quad! We even don't know if Ati can switch off any quads dynamicaly!

Not even close buddy:stick: You physicaly CANT'T have 300 watts cooled in the space of 3 slots, let alone 2. The Big Typhoon cooler maxes at about 200 watts cooling power. I seriously doubt the r600 can be 300watts. Not to mention the PCI-E x16 specification is 75watt for the main connector, and 75watts per 6 pin connector.

That's the whole system, a measly 264 watts for a X1900XTX system. I bet the PSU companies are celebrating, everyone will think they'll need a 1kW PSU for their system. :rolleyes:

Power consumption and power dissipation are two different things ;)
And imo nobody prevents vendors to add second power connector to the VGA

For 300watts of heat out put, you need 300watts of electrical input...looking through some PCI-E specifications, it apears to be a max of 150watts per card total power draw. The only cards i've seen with dual 6pin connectors were some early 7950GX2s, now they only have 1 connector.

For the R600 to use 300watts of power, it would need 3 6pin power connectors, ATi is not THAT dumb to do that. Most if not all PSUs only have 2 6PIN connectors

Current X1900XT cards push out around 120watts full load on STOCK speeds. A relatively dinky looking Zalman VF900Cu can already handle it + some OCing as well. Doubling that isn't too much of a problem for running @ STOCK speeds.

From what i've head, the vf-900 can bearly handle the x1900XT at stock

from what i know it depends.some cards can easily be cooled by a vf-900 and other x1900xts are hotheads and cant get decently cooled by a zalman.

I'm SOOOO glad, that I already have a sepperate H2O system for my GFX. Danm it's going to be a hot loop otherwise.
Triple radiator's for a CF setup alone, and that will still not be adequate for heavy OC'ing :eek:

I'd bet money it will. Anything over 500W is overkill unless you have SLI or CF. If it's not then your PSU has low efficientcy. X800XL <--- last card I owned that ran with out a 6pin ; ;

They cannot go over the specification of PCIe which only allows <150W.

leviathan18,
The PCIe spec max of 150W includes the wattage both slot (75W) and the 6pin connector (75W) provide combined.

An external PSU (http://content.answers.com/main/content/wp/en/thumb/5/59/250px-Voodoo_5_6000.jpg) will be needed if they'r going to go over 150W.

they are using more than 150w right now......

AFAIK, X1900XTX is the worst current hog of the GPU hoard with a max power draw of 120 watts (http://www.xbitlabs.com/articles/video/display/gpu-consumption2006_4.html).

Depending on when the big name games Crysis, and Ut2007 hit, i might go For a dual GPu setup, but then id need a new Mobo.

Hmmmm. Guess ill have to wait and see. If they run well on a single card ill go for it, but i can afford a top of the line dual card setup, and i want one, ehehe.

maybe even sell the lot, and go for Conroe when Vista hits?

You may need a new psu as well as the mobo. I dont think your 520w powerstream will keep up coming the end of the year when newer gpu's hit. My 600w powerstream is probably seeing the end of its life too.

Indeed, thats why im either thinking keep everything and get 1 R600 (which is what i had planned), or do a whole system upgrade next year. Depends if Vista slips and the games i suppose.

cantankerous

07-31-2006, 05:39 PM

Im in the same boat, if im going to upgrade its going to be all out otherwise ill stick with what I have which is doing just fine and add 1 R600 for the next while.

Curious... since we know the R600 is out at the end of the year has there been any rumours on when exactly the next ATI card after that will be? Anything mentioned?

nn_step

07-31-2006, 05:50 PM

if the R600 is greater than 150w. there is no way in Heck that anyone would use it. the Cooler costs alone would prohibit it from being popular...

STEvil

07-31-2006, 08:06 PM

i'd use it.

Vapor

07-31-2006, 08:32 PM

I'd use it...I already bought a WC loop with an MCR220 dedicated to a single graphics card.

Heck, even 2x 250W (175W cores) would be doable with the set up....

I actually kind of like the idea of power-hungry GPUs....it'll make better cooling more worthwhile, but only acceptable if they can idle with low power-draw (don't want to pay for energy and heatup the room if I'm not doing anything).
