HD 2600 XT (DDR3): 19-23/36-50 W (Sapphire is best)

Could you please tell me the exact numbers for that Sapphire card?
Is it the Ultimate edition?

I suspect there are many factors involved in the errors between one place and another. I have some suspicions. First off, the methodology is not the same everywhere. I'm not actually sure about the proper way to test a graphics card. For example, you can use a multimeter to measure the current and voltage at the 12V power input, that is relatively easy. However, this doesn't account for power usage through the PCI-e slot.

Perhaps a good way would be to use a card with a known power consumption, and then use that to calibrate the system, then insert the new card. ?

Also, almost every 8800GT card out there right now is running different memory and GPU speeds, which definately plays into power consumption. Something else to think about.

I'm shifting between 8600GT and 8500GT. The specs of 43 and 40 watts must be for the GPU only on equal draw or something. Just looking at the passive cards from ASUS and Gigabyte the 8600GT looks more like 70W and 8500GT maybe like 40W. I dont know how much DDR3 draws compared to DDR2 but there must be a significant difference among others.

On the other hand if they function well with undervolting 8600GT might be the way to go nevertheless.

I've made a new data compilation from xbitlabs:

[outdated chart]

I'll try to update it when new reviews from xbitlabs are released.

Any idea of 8400GS power consumption? I assume it's similar to 7300GS?

Thank you :)

There are some missing popular cards, for example:
- Radeon HD 2400 Pro
- Geforce 8600 GT

Can anyone help me to get correct data for these cards so that I can add them to the table?

How would the HD 3450 256mb card fit into the scheme of things, as far as heat goes? I would specifically love to see the numbers for that card, and to know if it gets hotter than teh HD 2400XT when doing normal 2D stuff (photoshop). I just want a snappy little card that is the coolest card possible. I wouldnt imagine a video card would speed a system up as far as normal (non-gaming and non-rendering) computing goes.

According to these sites:
http://www.legitreviews.com/article/652/13/
http://www.hothardware.com/articles/ATI ... ve/?page=9

Idle power consumption of the HD 3650 and 3450 is almost the same than HD 3850.

So, for the purposes of cool and quiet, modern 2D cards, the 2400XT should be quieter. Although, if you want HD encoding (i dont) then the 3450 looks pretty impressive and inexpensive.

"For example, you can use a multimeter to measure the current and voltage at the 12V power input, that is relatively easy. However, this doesn't account for power usage through the PCI-e slot. "

Its possible.. Tyan S5396 work station board has a seperate 12v power connector on it that only powers the top pci-e slot... figure this out cause I didn't have all the power connectors needed. Got Tyan to confirm too. Using this you could basicaly get perfect current draw on 12v rail. I think all PCIe cards draw almost nothing on the 5v rail... no idea on how to get this... but this isn't the biggest issue imo. The biggest issue left woudl be how do you get 'peak' 3d power draw? What game / benchmark / whatever?

I'd say a benchmark or stress tool, like rthdribl or the ATITool artifact checker. Games tend to be processor bound in various circumstances, and the load tends to be uneven even if processor power isn't the issue.

Does the Radeon 2400 XT still have the lowest idel power consumption? I have a x1300 now and would love to save 10 watts at idle.

Thanks,
Chris

Yes, the 2400XT is probably the lowest-consuming discrete card available. An Intel GMA onboard system will be lower still, but those are obviously difficult to add retrospectively.

In the spirit of this thread, this is the most comprehensive and up-to-date list I've been able to find anywhere. Apologies if it's already been posted here and I missed it:

Thanks for the reply. My guess is most of the 2400XT cards are just 'reference' boards and that the "best" memory in terms of power consumption on the 2400 is GDDR3. (The review @ xbit mentions GDDR4 in the title but my guess is that's only for the 2600.)

How is it really with the idling temeprature of passive radeons 2400pro/xt please? Does anybody have personal experience with it? I found not very optimistic reviews on newegg:

Cons: The heatsink on this card gets very hot. A customer of mine actually claimed to have smelled melting plastic from her computer earlier today, and I can think of no other culprit. For the money we will be putting into a PCI fan, it would have made more sense to have bought a fan cooled 2600 in the first place. Maybe it's not too late.

thank you.

finally we got numbers for the hd 4850, from a half way reliable source (xbitlabs):

Lets hope that the 4850 idle power listed here is still being worked on and will go down with the 8.7 drivers as posted in the other thread.

New low consumption card are 4350 and 4550. Under 20w at load.
HD4350 have DDR2 memory, 64 bit
HD4550 have DDR3 memory, but just 64bit.

Consumption is very similar, but power is not.
HD4350 do in 3dmark 2006 2300-2600 points, HD4550 do 3700-4600 points.
Price: 4350 - from 33$ , 4550 512mb- around 50$

Hi, Great topic, but still I am a bit overwhelmed with the new vga cards.
I currently use the TNN 500 AF with a core2duo and a 7900 NVidia VGA card. I intent to update it to a quad-core 3Ghz, and now I am looking for a better VGA card, that does not exceef the 75W heat dissipation the chassis can handle. I'd prefer NVidia and 2x DVI-D outputs. Any suggestions?

Here are a couple of new articles dealing with graphics card power consumption with tables listing most of the newer cards:

guess this is the right place to post some numbers I got the other week testing some of my old cards.

This is just for reference, if you have an old system you want to make a fileserver of or something, and any gfx will do to make it work, AGP or PCI. Over the years I've gathered a few cards, and while I was clearing out all my other pc stuff I thought I'd better test these to see if they even worked.

numbers are total W numbers for an old board, think it had a Celeron 500 and an oem 235W PSU.

Code:
                               MB   bios   idle       
S3 Virge                 PCI    2     44     32    passive
Matrox G450 DH           AGP          48     34    passive
Diamond/Nvidia Riva TNT  AGP   16     51     36    passive
Asus LP 7100             AGP          51     37    passive
Asus 7100/Deluxe/Combo   AGP   32     56     41    passive
Asus 7700                AGP   32     57     44        fan
Asus 9450TD              AGP          66     50        fan


All could do 1024x768 ,24bit @75Hz minimum in XP, so are perfectly fine for remote controlling and surfing.


These result made me change the deluxe combo I had just slapped unthinkigly in my 24/7 internet machine to the riva tnt, (have a use for the 2 lower cards) and finally undervolting the cpu as well, which saved me 30W in total.


Those old 2MB pci cards are very cool running and should do fine for most things, so I'll be looking out for any in the rummage/rubbish bin of old pc parts...
Plus they work on both AGP and PCI-E systems, handy if you don't have a 2nd PCI-E card around when you're switching your working system to a new one.

A new 4670?

Looks to me like the new 4850. Power numbers barely lower, performance barely higher than 4850.
