Nice work! Any chance you could separate out the low profile cards into their own comparison table? :)

True, but those are only TDP ratings so they'd likely use much less that that.

Ummm... NO!

:P

That varies by brand essentially. Power readings by GPU will essentially still be the same though. Just find low profile cards you might like and compare them in the OP.

I had some issues looking for a GFX card. It seems you can get a pretty decent card for under $200 nowadays. I had to lower my specs somewhat because the target system was a Dell GX280 with a 350W PSU and no extra power connectors. I ended up purchasing the Gigabyte 9500GT (512MB) card because it didn't need extra power, and even though on the box it said I needed a minimum 400W PSU to run it, I haven't had any problems with it, and I [now] often play 3D games for hours on end without issue.

Also, There was no point going any beefier than the 9500GT due to the CPU bottleneck.

I've also come across a German website that measures graphics card power draw much like Xbitlabs do. Thing is, they use Furmark to stress the cards. This results in higher peak readings than what Xbit produce with 3Dmark06. I've done some basic testing and with my $20 power meter from Jaycar and I agree that with Furmark my 4870X2 draws a lot more power than under any other game I play.

Question is should I include these results in my data? For example the 4870X2 current peak 3d readings would go up some 100W. Now Furmark isn't what you'd call a benchmark that produces typical 3d game loads, but it does provide a max possible draw. What would you guys like to see in my data, typical 3D draw (what all/most websites show) or peak 3d as shown by this German site?

Some links:

Ok being a thread about the truth of graphics card power draw I'll be including the data I mentioned above in my information. As far as I can tell and can test myself those results are the real deal. Might be an unrealistic load put on the cards, but the truth of the matter is that they actually can draw that much with correct software and drivers.

I'm also updating this f*** off complicated excel sheet so it can cater for more info, as well as churn out an extra graph type and also show a rough "data accuracy" score for each card. So the more data I have on the card and the seemingly more accurate that data is the bigger the "data accuracy" score shown.

I got the new graph type (sorted by make/generation, ie like the ascii graphs in the OP) figured out yesterday. When I get home tonight I should be able to get the data accuracy thing happening.

Updates should be posted hopefully tomorrow if all goes well.

As you may have noticed I haven't updated yet. Although those more keen eyed than others would've noted the excel graphs have been updated and slightly revamped to include axis labels and title, data quality ratings etc.

I could've had everything done and posted yesterday but I started running into data integrity problems where I had 3D power readings that were seemingly quite accurate but were magnitudes apart in terms of the data I currently have. Turns out all that data were tests carried out using Furmark (as per the site two posts ago).

So what I think I'll do now is split out any Furmark or any benchmark in future that puts an unrealistic load on the GPU (thus drawing max power) and call those readings 'Peak 3D draw' whilst everyday readings taken using 3DMark or games (most current data, and what most sites test with) I'll rename as 'Typical 3D draw'.

So most cards will end up with at least the Typical 3D power draw, and usually also idle power, then as I find data will also include 2D draw and 3D peaks.

This'll probably take me this coming weekend to sort out, so major update should hopefully be early next week.



Another problem I have is keeping the ASCII graphs in the OP updated. It's rather labour intensive to up keep as I have to manually edit everything in them. And whilst it was necessary for the pre v3 forums, now that we can embed pictures, keeping them updated, especially after this coming update seems a waste of my time. I've already figured out an excel graph basically sorted in the same way the ASCII graphs currently are so I can just drop that in instead.

Any thoughts or objections to that?
I know that the ASCII version is good for being able to search it (also good for search engines) and for links, less bandwidth etc, but unless someone knows how to write VBA code to output excel data into ASCII graphs in a text file or something I'm going to have to drop it.
As for the linkage to the website where the data came from for each card, I'll post all current ones from the ASCII graph in a future post here for everyones reference, then any card I add in future after that I'll simply include a URL when I post updates.
