X1900GT vs. 7900GT

That has to be one of the worst Anadtech reviews ever done :eek: Absolutly no aa and af used in any of the benchmarks. And aa and af is where the x1900gt gets hurt greatly.

No mention of IQ and were not clear on what settings were used for any of the cards, except to say maximum for the screen shots. If Nvidia would just use good default settings, wouldn't be such a bother.

1800xt consumes more power.. Still I think you need a minimum of 450watts for this...

As for 7900GT you might be able to pull it off... One way is try it out.. What power supply is it? If it's generic dont bother..

It's a good quality psu made by Enermax. I do not know the specs for it other than it's one of the noiseless models. Would it be necessary to open the case to get all of the technical detail on it? Is this information written on the unit itself?

The following article says the power supply requirements of the 7900gt are same as a 6600gt.

Assuming the 6800gt sucks more power than a 6600gt, then my psu can handle a 7900gt just fine, right? That is, 6800gt>6600gt=7900gt in terms of power usage.

7900GT takes much wattage as a 6800 ulta..

NO it doesnt. Did you even click on the link he provided, genius?? A 7900gt under load uses the same wattage as a 6600gt which is MUCH lower than the 6800 ultra. Educate yourself before popping off ignorant comments. :rolleyes:





from the Xbit link.... "In fact, the GeForce 7900 GT consumes as much power as the GeForce 6600 GT that has only 8 pixel and 3 vertex processors! This graphics card could even do without any additional power at all since the PCI Express slot is capable of providing up to 75 watts to the installed device."

I did educate myself you non genius.. :rolleyes: Xbit isn't the only website that measures power consumption... How do we know this is accurate? Oh don't tell me you believe whatever any website tells you... :rolleyes: I don't take xbit too seriously... Their numbers always jump everywhere with benchmarks etc...

Under load 7900GT eats much power as 1800GTO... Which is basically a Radeon 850XT far as power consumption goes...

power.gif


6600 GT eats much watt as 6800NU... 6800NU eats about 50 watts less than the ultra

power.gif



So when does power consumption = exact power that is needed to run a card? These cards with 24 pipes need more to run... A 400 watt is really pushing it... Especially some off brand power supply... A good 450 watt should cover it... That is why I told him to try the 7900GT earlier in this post... He might get it to work or not... Really depends with what peripherals and what brand power supply...
 
Can't see how the 7900gt can compete with the 1900gt in a price/performance ratio. At least in Sweden (where i'm sad to say I live) the cheepest 1900gt costs 20% less than the cheepest 7900gt and from what i've seen the performance difference is nowhere near 20%. And if you want 512mb memory the cheepest 7900gt with that memory costs the same as the cheepest 1900xt which from what i've understood ourperforms it by a reasonable margin.
Granted I'm still on a old ti4600 so my hands on experience with either of the cards is nill but I would from what I know have a hard time to recommend anyone to buy the 7900gt over the 1900gt.

you said the 7900gt uses as much power as the 6800 Ultra and it clearly doesnt. is the top graph even from the same system they were testing? the system with 7900gt may have completely different components.

As much as the Ultra give or take few watts... :rolleyes:

edit:
They used exact same components for each card in each graphs... Those 3 graphs are from different systems... But you get the idea...

From Newegg minimum power requirement for EVGA 7900GT:

System Requirements Minimum of a 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 20 Amp Amps.)
Minimum 500 Watt for SLI mode system.
(Minimum recommended power supply with +12 Volt current rating of 28 Amp Amps.)
An available 6 pin PCI-E power connector (hard drive power dongle to PCI-E 6 pin adapter included with card)

I don't see 6600GT needing minimum of 400watts to run.. That is why I said 450watts should cover it... If he didn't have a recent good power supply...

yeah and a 7600gs agp says 400watt for its requirements. my point is that a 7900GT uses no where near the power of a 680Ultra so you should not have said that. heres a chart from Anandtech showing total system load. the 7900GT barely draws more watts than 7600GT. a 6800Ultra would use almost TWICE the wattage of a 7900GT which only uses around 50 watts!

EVGA 7600GS AGP power requirement
System Requirements Minimum of a 350 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 18 Amp Amps.)
An available 4-pin Molex hard drive power dongle

(sarcasm) Hey GENIUS did you see Anand's graphs? How do you know 6800ultra eats up twice as much watts as the 7900GT... (sarcasm) :rolleyes:

Last time I checked most people were running x850xt and 6800ultra's on a 350 watt without a problem... As this is the power requirement on manufacturer's site...

So a 6800 ultra requires more wattage than 7950GX2 since 7900GT are clocked faster and 7950 is really 2 underclocked 7900GT.... Bwahahaha... Nice one... Tell me when it's over... I'm finished with this thread...
 
Nvidia Lowers GeForce 6800 Power Requirements
ExtremeTech, May, 2004 by Mark Hachman

An Nvidia Corp. representative confirmed Wednesday that the company has lowered its estimated power requirements for its GeForce 6800 Ultra GPU to the point where only a single power connector is required.

When the chip launched last month, Nvidia said that cards using the chips would virtually require users to connect two Molex power connectors in addition to the power drawn by the cards.

"According to Nvidia, the card will run using a single power supply connector; however, this setup leaves almost no voltage headroom, and any variance in the power supply's output could cause system instability," ExtremeTech analyst Dave Salvator wrote in his review of the part. "For this reason, the GeForce 6800 Ultra has two 12-volt connectors."

On Wednesday, an Nvidia spokesman confirmed reports that the company had fine-tuned the chip's power requirements, and only one power connector will be needed by users who wish to run the chip in normal operation. However, overclocking the GPU will still require the use of the additional connector.

Instead of a 480-watt power supply, users can use a quality 350-watt power supply, Nvidia is now specifying.

The eVGA box says 400watts for a 7600GS agp. the 7900GT is not clocked faster than the 7950GX2. the 7950GX2
also has 1 gig of memory so of course its going to use more power.


these are just a few reviews on the 6800Ultra power draw.

From tomshardware: "According to NVIDIA's numbers, the 6800 Ultra draws about 110 Watts"


From http://www.spodesabode.com/content/article/6800upower......"123.5 Watts overall, absolute maximum"


From http://www.pcmag.com/article2/0,1895,1583523,00.asp "In contrast, the new nVidia top-of-the-line processor requires two slots and has a peak power draw of 110 watts."


From http://pcworld.about.com/magazine/2304p144id119585.htm "The GeForce 6800 Ultra graphics card from NVidia can draw over 100 watts at peak usage."


the lowest peak usage I could find anywhere was just under 90 watts and that was AFTER Nvidia "finetuned" the chip. guess what.... that is TWICE the power consumption of the 7900GT. get over it.
 
I think you love birds should take your tiff into pm ;) it ain't all about what wattage you pack ;)

The guy has made his decision ffs
 
X1900GT for the win. Just got one overnight shipped from newegg for 220 bucks. Can't really beat that. Seems much faster than my x800pro. Seems pretty nice. I like the desktop Avivo Color option which was much missed from my last Nvidia card. At least this Sapphire card has ViVo. The last few ATI cards i've had have worked out much better than my Nvidia cards as so, so far, so good. I'll stick with what works.

Oh, by the way guys, no problems running on an Antec 430 watt PSU with 20 amps on the 12V rail. I have two optical drives, two hard drives, an Athlon 64 overclocked to 2.4GHz, 4 sticks of 512mb DDR @ 200Mhz and a SB Audigy 2ZS hooked up to this rig along with about 4 USB devices. I figure that's a solid amount of things and so far so good. :)
