AMD’s Radeon HD 6870 & 6850: Renewing Competition in the Mid-Range Market
by Ryan Smith on October 21, 2010 10:08 PM ESTFinal Words
Going in to our first meeting with AMD, we weren’t quite sure what to expect with the Radeon HD 6800 series. After all, how do you follow up on the blockbuster that was Cypress and the Radeon HD 5800 series?
The answer is that you don’t, at least not right away. With AMD’s choice of names in mind, Barts and the 6800 series isn’t the true successor to Cypress; but it is the next generation of Radeon for another market. That doesn’t mean it isn’t a great product line though – in fact that’s far from it.
The 6800 series hits the one market segment that AMD couldn’t reach with either the 5800 series or the 5700 series: the $200 market. As we said back in July when we crowned the GTX 460 the $200 king, the most successful chips are those chips that are designed from the get-go for the market they’re being sold in. The GTX 460 succeeded where the Cypress could not, as the penalty for using a harvested Cypress chip for that market was too severe and AMD had little else to work with.
Now 3 months later AMD has their appropriate answer to the $200 market in the form of Barts and the Radeon HD 6800 series. The Barts GPU is small enough to cheaply produce for that market, and with AMD’s rebalanced design it’s capable of trailing the 5800 series by only 7%, making Cypress-like performance available for prices lower than before. It’s the missing link that AMD has needed to be competitive with the GTX 460.
As a result, even with NVIDIA’s latest round of price drops AMD has managed to dethrone the $200 king, and in the process is reshaping the competitive market only recently established by the GTX 460. With AMD and NVIDIA’s price stratification there are very few head-to-head matchups, but there are a few different situations that bear looking at.
At the top end we have the Mexican standoff between the recently price-reduced GTX 470, the newly released Radeon HD 6870, and the overclocked GTX 460 as represented by the EVGA GTX 460 1GB FTW. At $260 the GTX 470 is several percent faster than the 6870, and at only $20 more NVIDIA has done a good job pricing the card. If performance is your sole concern, than the GTX 470 is hard to beat at those prices – though we suspect NVIDIA isn’t happy about selling GF100 cards at such a low price.
Meanwhile if you care about a balance of performance and power/heat/noise, then it’s the 6870 versus the EVGA GTX 460; and the EVGA card wins in an unfair fight. As an overclocked card in a launch card article we’re not going to give it a nod, but we’re not going to ignore it; it’s 5% faster than the reference 6870 while at the same time it’s cooler and quieter (thanks in large part to the fact that it’s an open-air design). At least as long as it’s on the market (we have our doubts about how many suitable GPUs NVIDIA can produce), it’s hard to pass up even when faced with the 6870.
Without the EVGA card in the picture though, the 6870 is clearly sitting at a sweet spot in terms of price, performance, and noise. It’s faster than the 5850 while drawing only as much power and yet it’s still slightly quieter. Meanwhile it completely clobbers the reference clocked GTX 460 1GB in gaming performance, although with NVIDIA’s new prices and the $30 premium we would hope that this is the case. If nothing else the 6870 wins by default – NVIDIA doesn’t have a real product to put against it.
As for the Radeon HD 6850 however, things are much more lopsided in AMD’s favor. It’s give and take depending on the benchmark, but ultimately it’s just as fast as the GTX 460 1GB on average, even though it’s officially $20 cheaper. And at the same time it draws less power and produces less noise than the GTX 460 1GB. In fact unless the GTX 460 1GB was cheaper than the 6850, we really can’t come up with a reason to buy it. For all the advantage of an overclock when going up against the 6870, the stock clocked card has nothing on the 6850. Even the GTX 460 768MB, while $10-$20 cheaper than the 6850, still has to contend with the fact that the 6850 is almost 10% faster and only marginally louder.
In fact our only real concern is that while the reference 6850 is a great card, the XFX card is less so – XFX heavily prioritized temperatures over noise, and while this pays off with a load temperate even better than the GTX 460, it comes at the price of noise levels exceeding even the 6870. Shortly before publication we got a note from XFX that they’re going to work on releasing a BIOS with a less aggressive fan, which hopefully should resolve the issue. In the meantime we suggest checking back here next week, as we’ll have several custom 6850s arriving next week that we’ll be reviewing as part of a 6850 roundup.
Wrapping things up, we believe this will probably go down as being the most competitive card launch of the year. AMD and NVIDIA reposition themselves against each other with every launch, but by first launching the Radeon HD 6000 series against NVIDIA’s mid-to-high range GTX 460, AMD has gone head-first in to one of NVIDIA’s most prized markets, and NVIDIA is pushing right back. If you would have told us 3 months ago that we would have been able to get GTX 460 1GB performance for $180 only a couple months later, we likely would have called you mad, and yet here we are. The competitive market is alive and then some.
Ultimately this probably won’t go down in history as one of AMD’s strongest launches – there’s only so much you can do without a die shrink – but it’s still a welcome addition to the Radeon family. With a new generation of Radeon cards taking their foothold, we now can turn our eyes towards the future, and to see what AMD will be bringing us with the Radeon HD 6900 series and the Cayman GPU.

There was a graph where a 4XXX series card beat the 6XXX series card...There were many where the 5XXX series was higher...Tesellation performance is higher on the 460 GTX and SLI scales better than crossfire...What the tesselation performance graph really means is that if you were to take an 460 GTX and 6870 and turn off tesselation and play a game....the 6870 gets a higher framerate, but if you turn on Tesselation on Both cards and go full force with Tesselation and other features (considering that Nvidia has support for PhysX and most games now have some physics implementation)...the outcome shows the 6870 taking such a performance hit that as far as framerates go....a 460 actually matches it or beats it outright.
What ATI/AMD really needs to work on is Integrating more technologies on its card to actually have more options during a game. No physics processing, Just an optimization on AA and AF...and tesselation performance that doesn't come close to a 460, along with horrible linux support...I really wonder and hope that their flagship card shows something steller....
Not to argue against it, but for the deserving ATI/AMD fans who have stuck with them over the years. ^_^

Prices are high for both in my country (Belgium).199 Euro for the 6850 and 279 euro (in the cheaper shops, upto 350 in others) for the 6870.
Very bland release for us, nothing to get excited about at that price point.
I also take offense to the naming scheme, why pick a name that will inevitable deceive many people into buying a sidegrade.

There was not nearly enough discussion on DTS HD MA and TrueHD pass through in this article. Gaming is 50% of the reason to upgrade, the rest of my focus is HTPC use. Please compare the GTX 460 vs the 6870 regarding bit-streaming, video quality and hardware decoding.Thanks.
P.S. Nvidia usually does a pathetic job on anything not related to gaming.

I think you guys are a little off on calling the 6870 the $200 price point King. The cheapest retail for the card right now is $239.99 for any model and then you have to add in another $5~10 for shipping. That sticks it at $245 - $250. That's no where near the $200 price point. And with most GTX 460 1GBs sitting at about $170 - $190 (w/ shipping), this card is not competing with them on price at all. Maybe in a few months if prices drop, but not now. It's more in the GTX 470 range and that is much tougher competition. I'm sorry, but the 6870 is NOT the $200 price point King. It's not even close.Lolimaster - Sunday, October 24, 2010 - link
HD6850 offers better performance tha 460 1GBHD6850 costs $175
HD6870 kill both of them, and also 470 performance/power consumption (80w less)
Scootiep7 - Sunday, October 24, 2010 - link
Ok, I'm sorry, but I have to laugh at this. Where the hell are you finding a 6850 for $175. The cheapest ANYWHERE is $199 and you still have to factor in #8ish shipping. Re-read my post and realize that the prices I quoted are accurate and you're still looking at a $30 price difference between the 6850 and the 460 1gb. Yes the performance is better, but it's not amazingly better and I don't think it justifies it. Hey, I'm all for the red team this time around. I picked up a 5770 which is an amazing bang for the buck card. I'm just saying that calling the 6870 or the 6850 the new $200 price point king is wrong. Too many variables.orthancstone - Friday, October 22, 2010 - link
I'm especially pleased to see the 4870 included in some benchmarks. As someone who owns one and who was never impressed with the performance boost/cost ratio of the 58/59xx lines, I've been wondering how the 6xxx line would compare to the two generation old stuff. I'd love to see it included in the third party 6xxx reviews.Edison5do - Friday, October 22, 2010 - link
As a owner of a HD 4850 was planning to get an HD 5770 but at this point it looks like HD 6850 looks like a better option with a few more bucks.. or wait to see if the HD 5770 will drop price a little more....Sando_UK - Friday, October 22, 2010 - link
Anandtech is one of my favourite review sites and it's a real shame to see what's happened here. I don't know the reasons why you guys needed to include the 460 OC in this review (does sound like a fine card btw, but this wasn't the place for it) - can't see any reason this wouldn't have been much better compared in a separate article. The fact Tom's hardware did a very similar thing makes the whole thing fishy...New generations/architectures don't come along very often and deserve proper comparison and coverage - I'm not an AMD or Nvidia fanboi (happy to go with whichever is best price/performance/extras at the time) but we rely on you guys to give us the facts on a level playing field. I'm sure you have in this case, but even the suggestion of impropriety damages you (extremely good) reputation, and I think it's something you should really try to avoid in the future - be it AMD or Nvidia reviews.
Otherwise, thanks for all your hard work.

It's sad to say, but this review fucking sucks. UVD and the display controller have been overhauled but you make no mention of any of the changes. Are there still only 2 RAMDAC clocks? Or can you now use passive DP converters while using both of both DVI ports?And including an OC'd card because nVidia pushed you into it? Way to take a shot to your credibility. And no mention of its clocks or price... AND no overclocking numbers for these new cards when you are specifically comparing it to an OC'd card? I mean wtf, this review is not up to previous Anandtech standards.
