hum this seems like it would be a repeat of the past

somehow this seems the most probable option but still since the HD4870 I would have thought NVidia would slow down on doing always bigger GPUs...

overall the rumours seems to be based on extrapolations from what happened in the past

It would be nice if they would start downsizing on the actual size of these cards.

the die on the recent cards have been HUGE. it would be nice to see how this stacks up against the 5870, my money is on ATi this time around, and plus i have recently prefered ATi drivers (due to 0 problems and monthly updates), compared to multiple WHQL releases where things have been broken for nV. But lets not turn this into "flame gilly" or driver criticism. Point is... ATi is making money now on the new cards, and nV is still putting theirs togeather

Oddly, I don't really care about the die size, or the cost of GT300 (although if it's ridiculously expensive then there is no way I'd even consider it) but the bit that has me most horrified is that power consumption figure... 300w.

For those that missed it:

300w

Unless it's literally twice as fast as the 5870... it's not worth it.

...

Bloody hell...

After ATi did so well to get the power consumption of the 5000's down, it seems nVidia are going in the opposite direction.

I have just 3 words, BRING. IT. ON.!!! A nuclear powered Nvidia DX11 card that wipes the floor with any single GPU card and competes even with rival dual GPU cards.

This all comes down to what you believe in this article and/or what you want to put in your system. The power consumption for a single 5870 is 188 watts. According to this article the GT300 may give even the 5870 X2 a run for it's money, which some speculate will have 340 watt consumption.

If these numbers are true, personally I'd rather have a simpler solution in a single GPU card as powerful as the GT300, vs a dual GPU 5870 X2 that will no doubt run hotter and be more likely problematic in some games (As dual GPU cards often are), even if it means slightly less FPS in most games.

(EDITED)
Another article that sheds a bit more light. I wasn't happy hearing of Fudzilla being VR's main source. Even HardOCP is spreading false rumors about release dates.

http://www.tweaktown.com/news/13215/nvidia_says_40nm_yeilds_are_fine_gt300_on_schedule_for_q4/

Excerpts:

"They (Nvidia) are claiming that the reports of less than 2% yields were based on a mistranslated report from AMD’s competitive analysis team.

Also they say that the reports that the GT300 is a rebranded/respun GT200 are baseless. According to the report the GT300 is a ground up redesign and a new GPU."

I wouldn't expect anything better from ATI's reps, they often speak total garbage, like their CS reps do to their customers.

Indeed, I'd like to see something solid too. Because until we do, we have no idea. Except we know about the Radeon 5870, because it's out. So we have a rough idea, presuming clockspeeds aren't altered, how a 5870X2 will perform. But on GT300 it's all still FUD or fanboy supposition.

From the shots of the 5870X2, it's got 8-pin and 6-pin PCI-E power connectors... that would mean 75w from the slot, 75w from the 6-pin and 100w from the 8-pin.

How anyone managed to get 340w out of 75+75+100 is beyond me.

PCGH have something too. Although it seems to be mostly repeats of elsewhere (FUD via VRZone). If GT300 can match the 5870X2 (when each are released) as a single card, then it'll be exciting times. Let's hope both the X2 and GT300 hit before Christmas. :D

edit: I vaguely remembered seeing somewhere that video cards are allowed to break PCI-E specs and draw in excess of 75w from the slot, but the standards sheets are explicit: 75w max and only. Further, from other reports, most graphics cards will draw power preferentially from the 6-pin and 8-pin connectors, rather than the slot, as the power is cleaner coming straight from the PSU rather than through the mobo traces.

edit 2: There is a paper on PCI-SIG covering a proposed PCI-E 16x 150w specification. I don't belong so can't get to it, but it seems like PCI-E 3.0 might, potentially, allow 150w per slot...

From what I've read even the 4870 X2 has been known to show as high as 370+ watt consumption in synthetic bench tests. I think you're oversimplifying your method of trying to determine max power consumption.

And as far as the talk of the GT300 being "all still FUD or fanboy supposition", not necessarily.

This would appear to verify 3 key things, 2 of which falsify earlier rumors. A 40nm process, contrary to ATI's so called report that was likely intentionally mistranslated ( I think Nvidia was being kind with those words), a non GT200 architecture, and 3 friggin billion transistors!

I say again, 3...BILLION... TRANSISTORS!

So I ask you at this point, does it really sound like the GT300 using 300 watts makes it inefficient, or that it makes it a stand alone, no SLI required freak of nature?

My only concern at this point is what speed a 920 will need to be clocked at to avoid a bottleneck. Preferably I'd like to avoid overvolting the CPU, but at this point I'm wondering if it will be necessary just to run this monstrous GPU without the system being unbalanced.

The only figures I can find that really hammer a 4870X2 (with Furmark) is on Overclock3D. 495w for a system about as close to my Core i7 rig as I've seen - 3.8GHz 920, 6GB Corsair, Gigabyte UD5, XFX 4870X2... I've got more HDDs though... that's from 336w idle in Windows, so that's a 160w idle/load jump. Now I know that the 4870X2 (and the 4000 series in general) isn't all that efficient at idle, but it's not horrible...

http://www.overclock3d.net/reviews.php?/gpu_displays/xfx_ati_4000_series_round_up/6

Just found some TechPowerUp data showing card power figures. 4870X2 idle is 73w, average 236w, peak is 273w and maximum is 381w, which yes, seems a little scary. I bet that was Furmark hitting all 1600 shaders for everything it could.

Compare that to the 5870 at 19w (idle), 122w (average) 144w peak, 212w (maximum)...

On paper, adding up the power provided from each possible source of power should be sufficient. However it's obvious that in specific scenarios designed to hit the cards as hard as possible, there is no limit on what they draw, short of blowing the PSU.

Does make me wonder what the maximum power draw of GT300 will be, though... :shock:

And as far as the talk of the GT300 being "all still FUD or fanboy supposition", not necessarily.

Actually, I meant about both the 5870X2 and GT300. Pics and figures are all very well, but I'll only be happy when we've got solid figures from multiple sources, rather than fifteen places all referencing one Fudzilla, Inq or BSN article... because all three of those places are good at 'imagining' stories for page hits. ;)

Yeah, looks sweet. You did notice the [Rumour] tag, though, yeah? ;)

Only solid info we've got to go on about performance of any of these cards is the fact that the 5870 is released. All the other cards are guesswork at best or outright lies at worst...

the spec is the spec though Frag. The power consumption for the whole system might be that high, but depends on what you mean. Im sure if you work the wattage out of the card it would be no where near 370w.

The card itself should only draw max 100 + 75 + 75 = 250w.

if the card draws too much im sure that would cause problems. I can understand however... you can get more than 75w from a PCI-e cable. Im sure if you stress it a bit, you can pull a lot more from that, you can draw more current than you are allowed I am sure.

As for how much I dont know. We could also only speculate on the connectors for the GT300.

300w - 75 leaves 225w for the PCI-e slots, that would be 2x 8 pins and a molex or something. Holy crap :P
