AMD’s Radeon HD 6870 & 6850: Renewing Competition in the Mid-Range Market
by Ryan Smith on October 21, 2010 10:08 PM ESTNVIDIA’s 6870 Competitor & the Test
As we mentioned on the front page of this article, AMD and NVIDIA don’t officially have competing products at the same price points. The 6870 and 6850 are more expensive than the GTX 460 1GB and 768MB respectively, and above the 6870 is the GTX 470. However NVIDIA is particularly keen to have a competitor to the 6870 that isn’t a GTX 470, and so they’re pushing a 2nd option: a factory overclocked GTX 460 1GB.
As a matter of editorial policy we do not include overclocked cards on general reviews. As a product, reference cards will continue to be produced for quite a while, with good products continuing on for years. Overclocked cards on the other hand come and go depending on market conditions, and even worse no two overclocked cards are alike. If we did normally include overclocked cards, our charts would be full of cards that are only different by 5MHz.
However with the 6800 launch NVIDIA is pushing the overclocked GTX 460 option far harder than we’ve seen them push overclocked cards in the past –we had an EVGA GTX 460 1GB FTW on our doorstep before we were even back from Los Angeles. Given how well the GTX 460 overclocks and how many heavily overclocked cards there are on the market, we believe there is at least some merit to NVIDIA’s arguments, so in this case we went ahead and included the EVGA card in our review. As a reference point it's clocked at 850Mhz and 4GHz memory versus 675MHz core and 3.6MHz memory for a stock GTX 460, giving it a massive 26% core overclock and a much more moderate 11% memory overclock.
However with that we’ll attach the biggest disclaimer we can that while we’re including the card, we don’t believe NVIDIA is taking the right action here. If they were serious about having a higher clocked GTX 460 on the market, then they need to make a new product, such as a GTX 461. Without NVIDIA establishing guidelines, these overclocked GTX 460 cards can vary in clockspeed, cooling, and ultimately performance by a very wide margin. In primary reviews such as these we’re interested in looking at cards that will be around for a while, and without an official product from NVIDIA there’s no guarantee any of these factory overclocked cards will still be around.
If nothing else, pushing overclocked cards makes for a messy situation for buyer. An official product provides a baseline of performance that buyers can see in reviews like ours and expect in any cards they buy. With overclocked cards, this is absent. Pushing factory overclocked cards may give NVIDIA a competitive product, but it’s being done in a way we can’t approve of.
Moving on, for today’s launch we’re using AMD’s latest beta launch drivers, version 8.782RC2, which is analogous to Catalyst 10.10. For the NVIDIA cards we’re using the WHQL version of 260.89.
Keeping with our desire to periodically refresh our benchmark suite, we’ve gone ahead and shuffled around a few benchmarks. We’ve dropped Left 4 Dead (our highest performing benchmark) and the DX11 rendition of BattleForge for Civilization 5 and Metro 2033 respectively, both running in DX11 mode.
With the refresh in mind, we’ve had to cut short our usual selection of cards, as we’ve had under a week to (re)benchmark everything and to write this article, shorter than what we usually have for an article of this magnitude. We’ll be adding these new cards and the rest of our normal lineup to the GPU Bench early next week when we finish benchmarking them.

Can you provide a link to your website so I can read your review of the cards? That would be awesome.Natfly - Friday, October 22, 2010 - link
Sure, right here: http://tinyurl.com/36ag36dBlendMe - Friday, October 22, 2010 - link
So you're telling me I can get two 6870 and spend lest money, use less power and have more performance than a GTX 480? I like the idea of going back to what made the 48xx cards so great. Small, cheap and expandable.Can't wait for the rest of the line up.

how is it that the nvidia cards go UP in framerate when you increase the resolution from 1650 to 1920 and add 4xAA? Did you mix up some test run numbers?mapesdhs - Friday, October 22, 2010 - link
It's a pity the charts don't include SLI results for the EVGA 460. I would like to have seen
how close it came to 470 SLI, given the 470s inferior power, GPU load temp and noise
results. The 470 GPU load temps under Crysis for just one card are particularly scary;
the idea of using two 470s SLI, and even more so oc'ing them, seems like a recipe for
thermal mayhem - alien astronomers with IR telescopes would wonder what the heck
they've spotted. :D
The price drop on the 470 is interesting, but the EVGA 460 still looks like a better buy
because of the power/heat issues, especially so for those considering SLI (as I am),
and also the fact that the EVGA is as good or better than the 6870. This graph is the
one that interests me:
http://images.anandtech.com/graphs/graph3987/33232...
The stock 460 SLI is clearly nowhere near as good as 6870 CF or 470 SLI, but given
a single EVGA 460 matches the 6870, I'd really like to know how two EVGAs perform.
Any chance you could add the data later?
On the other hand, one could assume the 6870 should have some oc'ing headroom,
but toms' review didn't show that much of a gain from oc'd 6870s.
The 6870 here in the UK seems to be about 200 UKP (Aria, Scan), though the XFX
version looks to be an exception (178 from Scan). The EVGA is 174 (Scan, but no
stock yet). For those who don't want to spend that much, the 800MHz Palit Sonic
Platinum 460 has dropped down to only 163 (last week it was 183). I almost bought
two of the Palit cards last week, so I'm glad I waited.
Obviously the pricing is all over the place atm, and likely to wobble all over again
when the next 6xxxx cards are released. Either way, despite the lack of major
performance increases atm, at least there's finally some pricing/value competition.
I think I'll wait until the dust settles re pricing, then decide. Quite likely many others
will do the same.

Why did you run at 1920x1200 and not 1920x1080 ??most 1920x1200 monitors are extincted from the market and 1920x1080 is becoming the defacto resolution.

Well with bowing down to nVidia on the selection of "what" GPU to use, you have lost all credibility in my eyes. Even Tom's Hardware took a higher road and agreed to use the "hand picked" GPU, but limited the clocks to near stock settings, so there was a more "real" world comparison. Who nows if this isn't the first time that this has happened at Anandtech. I notice no rebuttals on Anand's part, so I'm guessing that they are quite amazed that people are seeing how one sided this issue is. This article wouldn't affect my purchase, since I look a several sites to draw a conclusion from. But my confidence in quality and fair reporting from Anandtech's reviews have been compromised, IMHO. I don't know if I will put any merit to any on Anand's reviews, time will tell.Sunburn74 - Friday, October 22, 2010 - link
Gee. You know whats all this about Anandtech losing credibility? Nvidia specifically asked them to test one card and the consumer benefits from having this information. Its not like anandtech didn't include the reference gtx460 as well. Anything that tells the consumer more about how valuable his dollar really is, is a good thing imo.I currently have an oced radeon 5850 and it annoyed the hell out of me trying to justify whether or not the extra 30 bucks I eventually ended up paying for it, was worth it. There weren't any reviews at the time you see...

You can't gauge value of an overclocked card against a stock card. You have no idea what the other card can do. What you are saying is nonsense if you really put two seconds into thinking about what you just said.mindbomb - Friday, October 22, 2010 - link
we are talking about factory oc'd cards.It's not like Anand was playing around in rivatuner.
