AMD Radeon HD 6850 Overclocking Roundup: Asus, XFX, & MSI
by Ryan Smith on November 8, 2010 12:40 AM ESTMeet The Asus EAH6850
Our second card today is Asus’s first Radeon HD 6850, the EAH6850.The EAH6850 is the latest member in Asus’s Voltage Tweak subseries of cards, offering official voltage modification capabilities for overclocking through Asus’s SmartDoctor utility. It’s also the first overclocked card in today’s roundup, featuring a stock speed of 790MHz core and 1000MHz memory, a mere 15MHz over the 6850’s standard clocks. As a result the overclock is a token overclock at best - it’ll edge out stock-clocked cards in testing, but the difference is nothing to write home about.
In terms of design Asus has more or less completely thrown out the 6850 reference design for their own design. Starting with the PCB, Asus has gone with a custom PCB that runs a half-inch longer than the reference PCB, giving the EAH6850 a final length of 9.5”. With this extension Asus has moved the 6pin PCIe power socket to the top of the card, removing the need for additional clearance behind the card and in the process making the power socket much more accessible. Notably there’s a spot for a second power socket, and given the longer length of the card we wouldn’t be surprised if Asus ultimately released a 6870 using this PCB.
Meanwhile the component selection on the card is the usual mix of solid state capacitors and chokes. We haven’t been able to identify the VRM components in use, but we believe Asus is using a different VRM arrangement than on the reference 6850. The card also features a metal spine running down most the length of the card, providing the extra rigidity that a longer card requires and preventing it from significantly flexing.
Attached to the top of the card is the now customary Asus DirectCU cooler, Asus’s highly effective cooler which we have seen on a number of Asus cards in the past. This open-ended cooler uses a pair of aluminum heatpipes attached to a copper baseplate to transfer heat to the card’s aluminum heatsink, which runs roughly 2/3rds the length of the card. Embedded in the middle of the heatsink is the 70mm “dustproof” fan, and a partial shroud keeps airflow directed out the front and the rear of the card. Meanwhile the MOSFETs serving as part of the VRM circuitry have their own heatsink attached through springloaded clips, with airflow coming off of the fan keeping this second heatsink cool.
As is the case with the other partner cards in today’s roundup, Asus has ditched AMD’s 6800 series Eyefinity port configuration in favor of the 5800 series Eyefinity port configuration. This means the card has two DVI ports and the HDMI port along with one full-size DisplayPort, allowing the card to drive up to 5 monitors through a DP hub.
Because this is a Voltage Tweak card, Asus’s software plays an important role here by providing control for the card’s voltage modification capabilities. SmartDoctor has not changed since the last time we’ve seen it, providing a functionally competent but ultimately second-rate overclocking experience, as SmartDoctor lacks meaningful monitoring capabilities. Truth be told, the latest betas of MSI’s Afterburner software are able to program the EAH6850’s VRM controller, meaning there’s no practical reason to use SmartDoctor as the superior Afterburner is available.
As for pack-in items, Asus includes their usual collection for an AMD card: a quick-start manual, driver/utility CD, molex-to-PCIe power adaptor, short CrossFire bridge, a pleather CD binder, and a DVI-to-VGA dongle. Which on that note we had a chance to talk to Asus’s video card product manager last week and asked about the VGA dongle – it turns out that while VGA is largely dead & buried in North America, it’s alive and well in the Asia-Pacific region. Asus is simply packing their cards the same way in all regions, which means they all come with the VGA dongle.
Finally, the EAH6850 comes with Asus’s standard 3 year video card warranty. EAH6850 can be found for around $185, putting it at a $5 premium over AMD’s MSRP.

The EVGA GTX460 FTW used in the previous article can be found at newegg for $229.99/$239.99 (less $10 if you rely on MIRs).The cards in this article can be found at newegg for $184.99/$189.99.
Ignoring all the flak anandtech took for including the FTW card in the first place, you are still talking two different price categories.
While I'm in favor of comparing of including OC competition in an OC review, it isn't an absolute necessity.
Further, it would be irresponsible to compare cards in different price categories.
Given the variation in price from these OC units and how much they fluctuate, its near impossible to keep such an OC comparison relevant for long enough to be useful.
As such, I don't mind the lack of OC competition.
In fact, I think Ryan did a great job by focusing heavily on the AMD to AMD (6850 OC vs 6870 stock) comparison.
As long as the same rules apply when nVidia's new cards (stock and OC) come out, I see nothing to complain about.

I disagree. Very few people are hard-capped at exactly X dollars. If I see that $20 more buys me 20% more performance I may just decide to shell out a bit extra coin. Taking this a step further, what is the point in including the GTX480? It's not even close to being in the same price category. It's used as a metric to show just what higher-end cards can do, and allows for the reader to quickly judge how long a past top-of-the-line part still has life before contemplating replacement with a middle-tier part.Personally to prevent muddying the charts I think one step above and below the price category (say +/- $50-75 for low/mid-range parts) is really all that is needed, but that SHOULD include the FTW. It's up to the reader to decide if the extra money, heat, noise, etc. is worth it for better performance. I do have to admit though that I like comparing my aging 4870 to the competition and it was nice to see it displayed in this review to remind me of the performance increase I could be seeing on my gaming system (currently game at 19" LCD so it's tough to justify as everything still plays great at that low resolution).

7Enigma, read the title. If you are concerned with relative performance at given price points for the purpose of informed shopping, seek out articles similar to 'best graphics cards for the money' articles like Tom's runs. Also, criticizing their decision to include the 480 because of price seems irrelevant, they are measuring the performance of various 6850's as per the title, the rest of the cards are just simple reference.In this case, an additional $75 dollars represents around 40% of these cards initial cost. That's a pretty big extra expense. If i were in the market for a $20,000 car, I wouldn't see myself casually spending an extra $8,000 to take advantage of a deal. Presumably, this article is aimed at readers who already have decided on the 6850 and want to know more about those particular cards, not readers shopping different price points.
If Nvidia feels the OCed 460 is a better representation of that model, then they should respec the 460 at those speeds (i.e. GTX465). Until then, respect ATs decidion to leave out non-reference boards unless they are particularly relevant to the article (GTX 460 roundup). For reviews to remain relevant they must measure the nominal performance of specific models so average readers don't get confused/misled; people like you are already very well informed about the ever changing GPU market.

I would also like to see an overclocking comparison between Nvidia and AMD. I reveiewed the article here:http://www.anandtech.com/show/3810/nvidias-geforce...
The nvidia cards are behind by ~6 fps in crysis and more or less equal on Bad Company 2. That appears to be the only apples to apples games comparison.
However, there is a key difference. No attempt was made to overclock the Nvidia memory, which you claim is key in the AMD article. I'm no expert, so maybe nvidia memory doesn't overclock well and the comparison is fair. However, there does not appear to be an apples to apples comparison in the recent AMD article, and I think this is worth a revisit.
Willhouse - Tuesday, November 9, 2010 - link
Oops, sorry. I re-read the 6850/70 launch article and the GTX460 FTW performance is a pretty fair comparison (the memory was overclocked somewhat) to the cards from this article. Its omission from this article is strange to me though.blandead - Monday, November 8, 2010 - link
why would the gtx460 ftw it has nothing to do with this, go cry a river.its about 3 overclocked cards and reference others. not super super overclocked 460 ftw which is a competitor to 6870 in first place. so yea go look if you want.

The damage to Anandtech's image is already done. Before I easily trust every words it says. Now I look at these articles with grins of salt. It's a commercial website after all. Just read it as a joke.Minion4Hire - Monday, November 8, 2010 - link
??????Are you kidding? You're kidding, right?
Anandtech is a site that gives a shit about its readers. They respond very well to feedback and always try to do well by their audience. You have literally NO clue about what this site is about and what they have done over the years.
This supposed OC 460 debacle is a joke. I read the original article without the slightest problem with it and was entirely surprised when a bunch of oversensitive people got all butt hurt over nothing. What's wrong with comparing any given card(s) at any given price point(s)? The data speaks for itself. EVGA managed to offer one very competitive GTX 460. Kudos to them. I really don't care where or how Anandtech sourced said 460, they were able to include it in the article and that's awesome. The more data the better.
Seriously, Ryan, Anand, just do your thing. Don't worry about offending anyone and don't hold back. You guys serve up great content, and have consistently done so for some time now. I and many others look forward to the rest of your Barts coverage as the other 6000-series products trickle their way into the market.

This "supposed OC 460 debacle" is a joke to you because you are a NV fan. I am using a GTX480 but I'm disgusted by NV's PR actions.Did NV PR called Anandtech asking him to include an OC 460? Yes he did. And he included a limited edition that has the highest OC percentage. No matter what you say.
AnnonymousCoward - Tuesday, November 9, 2010 - link
Limited edition? Is that why it has been for sale, in stock, ever since the article came out??The debacle was a complete joke. As if it shouldn't be allowed to compare a product with "OC" in the model number, because model numbers really mean so much.
