is that video card any different than the current powercolor fanless 5750? it looks like the same cooler.

"Power Color Go! Green HD5750 consumes 21% less power than reference board."

Only difference, that and the price of course.

I'm guessing they removed the need for the 6-pin PCIe power connector?

This card was rumored last monht, it's without power connector.
From design point of view, I'd rather see that HS goes to the back of the card, something like HR03. I think this is better for most cases of passive use, as the heat goes up and does not hang below the card.

More interesting to me is saying how they kept power down... and brings me back memories at 4670 launch, where review cards had so much better power consumption compared to retail cards. At last something is moving.

Lower voltages in combination with selected GPUs and a simpler (less parts) voltage regulation i'd guess.

As far as I remember, the first fanless Powercolor 5750 that came out, used a lot more power than the reference 5750's.

Does anyone know for a fact, that their Go Green edition uses as little power as the reference, or even less? If so, I'll purchase it right away.

I couldn't find this in stores, I wanted it so badly.

I went with the powercolor 5750 fanless (non-green) and it doesn't use that much juice. I'd say between idle and Furmark-loaded it changes about 60 watts on my Kill-a-watt.

But the green one doesn't have a power plug and so it definitely will use less.

This site has some photos of the card. I can't wait until there's a review, hopefully from spcr!

Am I wrong or all these 5750 are like ghosts?
I've never seen one of'em here in Italy, nor on the web.

In Italy there is runstore.it who sell the Powercolor and the Club3D, but not the "green" one

This card was discussed in another thread http://www.silentpcreview.com/forums/vi ... p?p=494520

I still haven't found one for sale.

PowerColor Go! Green HD5750 1GB GDDR5 AX5750 1GBD5-NS3DH

According to the danish importers, we won't see the card here in Q1.

I'm extatic that someone finally makes an EE 5750 but still waiting for the single-slot 5750 EE to replace my XFX 9800GT EE with it's 66w board power. By single-slot I don't mean the HSF as I don't mind hacking up the side of my shuttle as I have extra covers but I just want a single pci bracket with a DVI, HDMI and DP.

Anyways, thanks for getting my hopes up by making me think I can retire my 9800GT OP =.=

===EDIT===

Ooh, I just noticed the PCB provision for a 6-pin PCi-E connector, good for modding one on should someone ever want to OC the card

Finally available for preorder in EU.

http://geizhals.at/eu/a496815.html

Price is currently a bit steep, 35 euros more than non green passive 5750.

In stock in some german shops as of today.

One Canadian site is listing it for sale now, backordered, for $180cad.

Come on newegg!

Yes NCIX has it advertised the PowerColor Go! Green HD5750 1GB GDDR5 aka AX5750 1GBD5-NS3DH for $180, so I guess we can expect shipment shortly. I myself personally am trying to keep this card under wraps, because I wonder about the demand. To my knowledge it's the fastest card available with passive cooling, assumably working under 75 W, bitstream and passive and everything else that a 5000 series graphics cards would bring. As much as others are suggesting that the 5650 would be the perfect HTCP graphics card, I believe this card has the potential to be the best.

However, I have a couple of concerns. First ATI has not yet demonstrates that there graphics cards driver can handle Bitstream audio without any difficulty and ATI is not known for great drivers in the first place and particularly with regard to there are 5000 series graphics cards and more particularly with regard to bitstream.

See the expert's advice, and let's all pressed ATI for drivers to properly support the features that they advertise on their graphics cards, ie Bitstream, see below

avsforum*com/avs-vb/showthread.php?t=1224697

Secondly: I really wonder if this card can live up to its expectations; that is to say that it can rival stock 5750 ATI cards in terms of performance. I guess before purchasing I would really like to see a comparison between this card and say Sapphire Radeon HD 5770 Vapor-X Video Card both in terms of performance, temperature and noise levels. Granted PowerColor Go! Green HD5750 1GB GDDR5 is a passive card and one would expect no noise, but it's difficult to know whether or not the Sapphire Radeon HD 5750 Vapor-X Card (for example), can compete to a passive card in terms of sound (everyone says it’s the quietest card and makes no noise, but others say it makes the most noise in their system). So if it has an acceptable noise level then one would assume the 5770 would also have, ie. the same acceptable noise level, why would one buy a 5750 that has a cooling fan, when they could purchase a 5770 with the same fan and noise level. So in my mind, if the noise level of the 5770 is indistinguishable, then one would buy it, making the other two cards obsolete. If in fact the noise level of the 5770 is noticeable from a HTCP connoisseur's point of view and the performance level of the Green HD5750 is equal to the stock 5750, then one would choose that the Green HD5750, making the stock 5750 video card obsolete. (Price being of no consequence, within reason)

Let's hope that anandtech*com/ or extremetech*com/ or some other reputable source can get a hold of this card and make some comparisons between it and the most silent 5750 and 5770, both in terms of performance, sound and features, such that the HTCP community can make up their mind.

I mean let's face it; HTCP has got to be the highest growth computer segment out there. It's all about convergence, we have all dreamed about our computers sitting next to our televisions streaming music, video, and everything else that the Internet has to offer in our living rooms. But who wants to sit by their television and listen to the hum of a fan or the noise of a hard drive. We want quiet, we want 1080P, we want native audio and want to play the occasional game at levels above that of the PS3.

My last comment is to Nvidia: As much as I love you and appreciate your driver support; I hope you’re listening, because if you don’t have bitstream, quiet performance, etc. (YOU COME BACK…. TWO YEAR)

zipzoomfly has it listed now as well. $170 US.

Hi Folks,

I finally got one of those Cards!

First results, without any tweaking in Bios and standard C&Q:

MB: MSI 770T AM2+
CPU: Phenom II X4 910e with boxed Heatsink
Ram: Standard DDRII 800
HDD: WD 1GB Greenpower EADS
Power: Seasonic S12II 330

Idle: 75W
Furmark: 150W
3D Mark 06: 135W (Canyonflight)

This is much better than my hand tweaked Brisbane 5000+ and Bios edited HD 3850!

When the Rig is finished (watercooled etc.) I will post final Results.

I also tested it Briefly in a 785 Minix Board with the same CPU and it seems to have ca. 15W idle Power draw (which is the same as the other passive Powercolor with plug).

Looking forward to hearing more about it.

Newegg now has it. 5750

thats as much as a 5770

I Just read the Release notes of the latest RBE and noticed that it's not possible to tweak the GPU voltage of the reference HD 5750 due to a different VR Chip.

But....

Good News...

The Go!Green has the programmable VT1165MF for the voltage regulation. So it should be possible to tweak the power consumption even further.
The voltage regulation hardware is completely overhauled on the G!G.



I just checked the default voltages:

boot and high 3D: CPU 700Mhz @ 1.1V
2D: CPU 157Mhz @ 0,95V
low 3D: 500Mhz @ 1.0V
UVD/TV/Bluray: 400Mhz @ 0.95V

Does anyone know the default voltages of the reference HD 5750?

Greetz Audiodude

It's definitely not ideal cost performance, but it doesn't have the PCIe power connector and putting a passive heatsink on another 5750 would end up at a similar price point anyway.

Alright, I have waited for two months to get a passive HD5750 from a danish shop, but it will never get in stock.

Can someone help me find an online shop in Germany or UK who wants to ship to Denmark and accepts Mastercard or Visa payment?
For some reason, those I've found who actually ships to Denmark, only accepts Paypal and bank transfer.

hey kvik,

did you try http://www.alternate.de/html/product/details.html?artno=JCXOV7&? That's where I bought my Card and they offer Payment on delivery to denmark and I think credit card should be possible to. They are not the cheapest though.

Edit: Credit Card isn't possible, but payment on delivery (postman collects the money in exchange for the goods) this is called "Bar Nachnahme".

Greetz Audiodude

I searched and couldn't find it. I really appreciate the post with pics and voltages!

I just compared some Bios files from TechPowerUp! and it seems that the voltages are the same as with other Boards.
This would mean, that the lower power consumption is solely achieved by the more efficient voltage regulation circuits.

Greetz Audiodude

Why that?

If they had lowered the voltage, the card would already be at its best.
But with standard voltage there ist still the possibility of tweaking it even further...

By the way, i am really pushing this card today. The GPU is running dirt2 replays for hours now to heat up my Reserator. After that I ran Furmark for hours without overheating anything on the Mainboard (that's where the power comes from). I really think the claims of Powercolor are right.
The vr heatsinks and the mem heatsinks are at 65°C (measured with a decent ir thermometer).
Furmark measures 57°C for the GPU watercooled with ZM-GWB3 and the water Temps are at 40°C which seems high but is perfectly alright for the Reserator (ambient is 24°C).



So everything is cool.

Edit: I tried to measure the cards power consumption as good as i can(with a Conrad Energy Check 3000 at the wall socket).

From the Test with my minix board i know that idle power consumption is around 15W wich is pretty much the same as a good standard card.
In my rig with the MSI 770T-C45 and a
Brisbane dualcore @5x200 @0,8VCore fixed with crystalcpuid
the idle consumption is ca. 83W.

When Furmark kicks in (wich creates ca. 95-97% use), the consumption rises to 134W. That means a rise of 51W. If we add 15W standby consumption, we get 66W at load without taking into account that the cpu also uses a little bit more power at load (1 core is used 60-85%)

I think this definitely shows that Powercolor did their homework.
This card is a nice piece of efficient engineering.

Efficient engineering of power circuits has proven to save up to 20W at load with recent motherboards so why shouldn't that be possible with graphics boards where some vendors don't even bother to put the right circuitry on their products to get the reference consuption values.
