AMD’s Radeon HD 6870 & 6850: Renewing Competition in the Mid-Range Market
by Ryan Smith on October 21, 2010 10:08 PM ESTThe latest game in the Battlefield series - Bad Company 2 – remains as one of the cornerstone DX11 games in our benchmark suite. As BC2 doesn’t have a built-in benchmark or recording mode, here we take a FRAPS run of the jeep chase in the first act, which as an on-rails portion of the game provides very consistent results and a spectacle of explosions, trees, and more.
Our experience with Bad Company 2 more or less matches our experiences with other shader-heavy games at 1920x1200. The GTX 470, 6870, and EVGA GTX 460 all vie for the top of their pack within a frame of each other, while the 6850 enjoys a clear lead over the GTX 460 1GB. However what’s interesting is that the Radeon 5800 series takes a very obvious lead here, a lead that’s larger than in most other games. If you ever wanted to know just how shader-bound Bad Company 2 is, there’s the answer you’re looking for.
As for the Crossfire situation, once again the 6800 series closes the gap. Even the GTX 470 in SLI can’t quite keep up with the 6850CF, which is much a story of how well the game runs on AMD cards as it is a story of what’s clearly going on with the 6800 series and Crossfire.

No it more looks like NV have been playing around with rivatuner.Their cards at stock speed is a toaster. Overclocking again just before an AMD release does not make it better.
If they can sell cards at higher speeds do it. Release it. Dont talk about it, or coverdly hide behind factory overclocked cards. Pathetic and weak.
The sad thing about it is they made Anand change their methology.
What a sad result when the start was just bad gfx cards.

Not sure it was mentioned before: Cypress and RV770 run FP64 at 2/5th the FP32 speed, not 1/5th as written on the first page.MrS

It's 2/5 for addition, but 1/5 for multiplication and FMA as I recall it.krumme - Friday, October 22, 2010 - link
I you want real world testning for solid buying knowledge and no idiotic mixing of oc and non oc cards go to HardocpAnand needs to do a solid review of his own gfx reviews. This is stoneage methology with a fishy smell.
For the ssd there was an excellent revision with the real world bm suite introduction, - a revision far deeper is needed here.

I agree. Comparing a non-OC'd card to an OC'd one is in no way fair. The 6870 clearly clubbered 460 gtx in virtually all benchmarks, at stock speeds.krumme - Friday, October 22, 2010 - link
Yes. Think about this scenario: For this review anand (kyle) decided to use an overclocked Sapphire 6870 and compare it to a stock speed 460.What would happen? How would that look?
Its the same thing happening here.

if they are in the same price range, they should be compared.it gives the consumer more information on his purchasing decision.
idk why this arbitrary oc/non-oc rule comes into play. It was a factory overclock, and required nothing on the part of the end user.

Okey. Now take an OC 6850, 900Mhz, and compare it to a far more expensive stock 460 1G?Where does this end. AMD and NV suplying the sites with factory overclocked cards for reviews. Its going to be a f..king mess. No one knows about availability, time period and so on.
Regarding pruchasing decision all the methology is plain wrong. Go to Hardocp if you consider buying a card. Here you have real world testing. Not like this old bad - and now fishy - methology of anand.
Why does he change methology just when he is getting the new cards. Hmm. Thats simply very bad science.
NV should concentrate on making cards that performs instead of using ressources putting pressure on sites like anand. If they have faster 460 models release it, or stop spinning.
Its a pain to read and watch. And its a shame for a site, that have the ressources to do proper testing, but dont have the balls any more.
We dont like AMD, Intel nor NV to influence the reviews. Right now there is an obvious bad influence from especially NV. And you, and everyone can see it. Dont underestimate the consequenses.

You COMPLETELY missed the point. *IF* the OC 6850 was a factory overclocked card, sold at a price that puts it in the range of cards reviewed, then it *WOULD* make sense to compare it.So your example just further makes the point.

Well as it stands now they dont release oc cards at launch day, but that will soon change..., if Anand and others dont stick to their policy
