VGA Power ConsumptionLife is not as affordable as it used to be, and items such as gasoline, natural gas, and electricity all top the list of resources which have exploded in price over the past few years. Add to this the limit of non-renewable resources compared to current demands, and you can see that the prices are only going to get worse. Planet Earth is needs our help, and needs it badly. With forests becoming barren of vegetation and snow capped poles quickly turning brown, the technology industry has a new attitude towards turning "green". I'll spare you the powerful marketing hype that gets sent from various manufacturers every day, and get right to the point: your computer hasn't been doing much to help save energy... at least up until now. For power consumption tests, Benchmark Reviews utilizes the 80-PLUS GOLD certified OCZ Z-Series Gold 850W PSU, model OCZZ850. This power supply unit has been tested to provide over 90% typical efficiency by Chroma System Solutions. To measure isolated video card power consumption, Benchmark Reviews uses the Kill-A-Watt EZ (model P4460) power meter made by P3 International. A baseline test is taken without a video card installed inside our test computer system, which is allowed to boot into Windows-7 and rest idle at the login screen before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for each specified test product:
* Results are accurate to within +/- 5W.
The Radeon HD 6870 requires two six-pin PCI-E power connection for proper operation. Resting at idle, the AMD Radeon HD 6870 consumed 20W by our measure. Compensating for a small margin of error, this falls roughly in-line with AMD's 19W expected power draw. Once 3D-applications begin to demand power from the GPU, electrical power consumption climbed to full-throttle. Measured with 3D 'torture' load using FurMark, the AMD Radeon HD 6870 now required 162W. AMD's stated max TDP is 151W, and when factored with efficiency rating this is also within the margin of error. Loaded power draw matches the ATI Radeon HD 5850 and older ATI Radeon HD 4870. On the NVIDIA side, these figure compare to the GeForce GTX 460.

I love this review ( but would have likes multi gpu setup test)
With sandibridge around the corner, the entrylevel gpus will be dimineshed, AMD is stepping up its game in the mid level gpu section. ( because it will soon be entry level and not midlelvel)
I don't like that ATI and NVIDIA cards are so far apart as to how they do Phys-X and other newer game technologies. I'd like to see them both cleave to standards so we could rate them in a better and fair way against one another. ATI says that Phys-X is closed by the other guy, and NVIDIA say's it isn't,..........what a crock. They should both do it all.
Not knowing if Phys-X and Cuda will take off and be a part of every game makes me lean towards buying the cards that have it built-in to them just to ensure that I don't have to buy all over again later just to be able to play the next new wazoo games that developers are dreaming up. Thanks for the considered look at these new AMD Cards.
thats what i get, cause with the new prices 460 worth more and better tesselations VS non
otherwise ati boys stay with the 5850
So the 5830 doesn't exist anymore !
ROFLMAO - It's a hoot seeing so many geeks claiming to know something, and the entire red rooster set of intertards cannot bring themselves to type 5 8 3 0 .
Wow.
What card has 1120 shaders ? LOL
There are no less than 8 different 5830's available on the egg right now, exceeding a few other " quantity models".
Out of the 20-30+ reviews, I've seen ONE that logically and honestly claimed one of the cards "being replaced" was the 5830.
We have 5870, 5850, 5830 - not like it's easy to miss the 3rd card. You really have to work at it.
Those the masses and the two competing companies rely on for releases, affect the market quite substantially, yet they miss the single 1120 shader card ATI had on the table, when the 2nd 1120 shader hits ? Widely IT'S NOT EVEN MENTIONED NOR CHARTED IN ENTIRE ARTICLES.
"It's low in production" is a joke.
I have no idea if it's pressure or brainwashing or incompetence, but in any case no excuse will satisfy, period. I'm certain you understand that.
Now that AMD has released another set of competitors to the 460 in very short order, the 5830 falls into the amnesiac category. 8 different 5830's are currently available on one of the very popular online purchasing sites.
I've seen just one review actually mention the 5830 when reviewing the Barts 6000 release.
Those of us who are awake, obviously in the minority, have reason to be disturbed.
26 cards in total.
No 5830.
I'm not here to criticize you, but your last response is quite surprising to say the least. I don't suppose any card other than the GTX460 1gig "has anything to do with a $250 6870" , or perhaps we could just have a review with the 6870 compared to the 5850 or just the 5870, whichever the 6870 happens to be closest to. I suppose by your statement that's the 5850.
I will find more than the 5850 in the bench charts won't I.
I am sorry logic and comprehension and honesty isn't in the mix, all too often.
Believe me, it's not a conspiracy. I don't think it could be even if we really, really tried.
While you're at it, go back and re-read the 6850 review. It was re-written to compare against the 5770 and 5830.
i wanna play crysis2 on max settings so... which graphic card sholud i bu.
plzzz help me :(
ma budget is around 350-400$
