AMD Barts GPU OverclockingAMD's Cypress GPU was well-known for accepting massively overclocked speeds. The new Barts GPU is based on Cypress, and should in theory yield a similar overclock. This presumes that AMD hasn't already stretched the Radeon HD 6850 and 6870 as far as they could go. For this project, we used MSI's free Afterburner program to overclock the video cards. The MSI Afterburner "Graphics Card Performance Booster" application offers several adjustable variables to reach the desired overclock. Afterburner allows for voltage changes (increase/decrease), but this project aimed to stretch the AMD Barts GPU as far as it could go without any extra power applied. Beginning with the maximum stable GPU clock speed, I slowly increased the settings until I began to see tearing or the driver crashed. Once I reached the most stable speeds for both GPU and GDDR5, I put the video card back into action with high-demand video games for additional benchmark tests. Here are the results: AMD Radeon HD 6850 Overclocking Results
AMD Radeon HD 6870 Overclocking Results
Radeon HD 6870 TemperaturesBenchmark tests are always nice, so long as you care about comparing one product to another. But when you're an overclocker, gamer, or merely a PC hardware enthusiast who likes to tweak things on occasion, there's no substitute for good information. Benchmark Reviews has a very popular guide written on Overclocking Video Cards, which gives detailed instruction on how to tweak a graphics cards for better performance. Of course, not every video card has overclocking head room. Some products run so hot that they can't suffer any higher temperatures than they already do. This is why we measure the operating temperature of the video card products we test. To begin my testing, I use GPU-Z to measure the temperature at idle as reported by the GPU. Next I use FurMark's "Torture Test" to generate maximum thermal load and record GPU temperatures at high-power 3D mode. The ambient room temperature remained at a stable 20°C throughout testing, while the inner-case temperature hovered around 37°C. FurMark does two things extremely well: drive the thermal output of any graphics processor higher than applications of video games realistically could, and it does so with consistency every time. Furmark works great for testing the stability of a GPU as the temperature rises to the highest possible output. The temperatures discussed below are absolute maximum values, and not representative of real-world performance.

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 $250 6870" , or perhaps we could just have a review with the 6870 compared to the 5850 or just the 5870, whichever the 6870 happens to be closest to. I suppose by your statement that's the 5850.
I will find more than the 5850 in the bench charts won't I.
I am sorry logic and comprehension and honesty isn't in the mix, all too often.
Believe me, it's not a conspiracy. I don't think it could be even if we really, really tried.
While you're at it, go back and re-read the 6850 review. It was re-written to compare against the 5770 and 5830.
i wanna play crysis2 on max settings so... which graphic card sholud i bu.
plzzz help me :(
ma budget is around 350-400$
