AMD’s Radeon HD 6870 & 6850: Renewing Competition in the Mid-Range Market
by Ryan Smith on October 21, 2010 10:08 PM ESTKicking things off as always is Crysis: Warhead, still the toughest game in our benchmark suite. Even 2 years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and the answer continues to be “no.” One of these years we’ll actually be able to run it with full Enthusiast settings…
For reasons we’ve yet to determine, Crysis continues to do a very good job serving as an overall barometer for video card performance. Much of what we see here will show up later, including the order that cards fall in.
As we’ve been expecting, the 6800 series cannot keep up with the 5800 series – Barts is still a “rebalanced” Cypress after all. The performance gap isn’t too severe, and it certainly couldn’t justify 5870 prices at today’s prices, but the 6870 and 6850 definitely aren’t perfect replacements for their 5800 series counterparts.
Focusing on 1920x1200, we have a 3-way race between the GTX 470, EVGA GTX 460, and the 6870. The 6870 comes out ahead, with the EVGA and then the GTX 470 bringing up the pack at under a frame behind. Meanwhile near the 6850 is the GTX 460 1GB, and it’s 2fps behind; while even farther down the line is the GTX 460 768MB, which officially is only $10 cheaper than the 6850 and yet it’s well behind the pack. As we’ll see, the 6850 will quickly assert itself as the GTX 460 1GB’s peer when it comes to performance.
Meanwhile taking a quick look at Crossfire performance we see an interesting trend: the 6800 series cards are much closer to their 5800 series counterparts than they are in single card mode. Here the 6850CF even manages to top the 5850CF, an act that nearly defies logic. This is something we’ll have to keep an eye on in later results.
Moving on to our minimums, the picture changes slightly in NVIDIA’s favor. The 6870 drops to the bottom of its pack, while the 6850’s lead narrows versus both GTX 460 cards. Meanwhile in CF mode now both 6800 series cards top their 5800 series counterparts. Crysis’ minimum framerate has always been a bit brutal to AMD cards due to how AMD’s drivers manage their memory, a problem compounded by Crossfire mode. Perhaps something has changed?

Well that's odd.After reading about the EVGA FTW, and its mind-boggling factory overclock, I went looking to see if I could pick one of these up in New Zealand.
Seems you can, or maybe not. As per this example http://www.trademe.co.nz/Browse/Listing.aspx?id=32... the clocks are 763Mhz and 3.8 on the memory?!?
What gives, how can EVGA give the same name to a card and then have different specifications on it? So good thing I checked the fine-print or else I would have been bumbed out if I'd bought it and then realised it wasn't clocked like I thought it would be..

So..how about that update in the review checking out the quality/speed of MLAA?CptChris - Sunday, October 31, 2010 - link
As the cards were compared to the OC nVidia card I would be interested in seeing how the 6800 series also compares to a card like the Sapphire HD5850 2GB Toxic Edition. I know it is literally twice the price as the HD6850 but would it be enough of a performance margin to be worth the price difference?gochichi - Thursday, November 4, 2010 - link
You know, maybe I hang in the wrong circles but I by far keep up to date on GPUs more than anyone I know. Not only that, but I am eager to update my stuff if it's reasonable. I want it to be reasonable so badly because I simply love computer hardware (more than games per say, or as much as the games... it's about hardware for me in and of itself).Not getting to my point fast enough. I purchased a Radeon 3870 at Best Buy (Best Buy had an oddly good deal on these at the time, Best Buy doesn't tend to keep competitive prices on video cards at all for some reason). 10 days later (so I returned my 3870 at the store) I purchased a 4850, and wow, what a difference it made. The thing of it is, the 3870 played COD 4 like a champ, the 4850 was ridiculously better but I was already satisfied.
In any case, the naming... the 3870 was no more than $200.00 I think it was $150.00. And it played COD4 on 24" 1900x1200 monitor with a few settings not maxed out, and played it so well. The 4850 allowed me to max out my settings. Crysis sucked, crysis still sucks and crysis is still a playable benchmark. Not to say I don't look at it as a benchmark. The 4850 on the week of its release was $199.99 at Best Buy.
Then gosh oh golly there was the 4870 and the 4890, which simply took up too much power... I am simply unwilling to buy a card that uses more than one extra 6-pin connector just so I can go out of my way to find something that runs better. So far, my 4850 has left me wanting more in GTA IV, (notice again how it comes down to hardware having to overcome bad programming, the 4850 is fast enough for 1080p but it's not a very well ported game so I have to defer to better hardware). You can stop counting the ways my 4850 has left me wanting more at 1900 x 1200. I suppose maxing out Starcraft II would be nice also.
Well, then came out the 5850, finally a card that would eclipse my 4850... but oh wait, though the moniker was the same (3850 = so awesome, so affordable, the 4850 = so awesome, so affordable, the 5850 = two 6-pin connectors, so expensive, so high end) it was completely out of line with what I had come to expect. The 4850 stood without a successor. Remember here that I was going from 3870 to 4850, same price range, way better performance. Then came the 5770, and it was marginally faster but just not enough change to merit a frivolous upgrade.
Now, my "need" to upgrade is as frivolous as ever, but finally, a return to sanity with the *850 moniker standing for fast, and midrange. I am a *850 kind of guy through and through, I don't want crazy power consumption, I don't want to be able to buy a whole, really good computer for the price of just a video card.
So, anyhow, that's my long story basically... that the strange and utterly upsetting name was the 5850, the 6850 is actually right in line with what the naming should have always staid as. I wouldn't know why the heck AMD tossed a curve ball for me via the 5850, but I will tell you that it's been a really long time coming to get a true successor in the $200 and under range.
You know, around the time of the 9800GT and the 4850, you actually heard people talk about buying video cards while out with friends. The games don't demand much more than that... so $500 cards that double their performance is just silly silly stuff and people would rather buy an awesome phone, an iPad, etc. etc. etc.
So anyhow, enough of my rambling, I reckon I'll be silly and get the true successor to my 4850... though I am assured that my Q6600 isn't up to par for Starcraft II... oh well.

The 6800 series my not beat the 5870 yet but it is the start of the HDMI 1.4 for 3dHD not available in any other ATI graphics cards.Philip46 - Monday, November 15, 2010 - link
The review stated why was there a reson to buy a 460(not OC'ed).How about benchmarks of games using Physx?
For instance Mafia 2 hits 32fps @ 1080p(I7-930 cpu) when using Physx on high, while the 5870 manages only 16.5fps, while i tested both cards.
How about a GTA:IV benchmark?, because the Zotac 2GB GTX 460, runs the game more smoothly(the same avg fps, except the min fps on the 5850 are lower in the daytime) then the 5850 (2GB).
How about even a Far Cry 2 benchmark?
Co'me on anandtech!, lets get some real benchmarks that cover all aspects of gaming features.
How about adding in driver stability? Ect..
And before anyone calls me biased, i had both the Zotac GTX 460 and Saffire 5850 2GB a couple weeks back, and overall i went with the Zotac 460, and i play Crysis/Stalker/GTA IV/Mafia 2/Far Cry 2..ect @ 1080p, and the 460 just played them all more stable..even if Crysis/Stalker were some 10% faster on the 5850.
BTW: Bad move by anandtech to include the 460 FTC !

Barts is the replacement for Juniper, NOT Cypress. Cayman is the replacement for Cypress. If you're going to do a comparison to the previous generation, then at least compare it to the right card. HD6850 replaces HD5750. HD6870 replaces HD5770. HD6970 replaces HD5870. You're giving people the false impression that AMD knocked performance down with the new cards instead of up when HD6800 vastly outperforms HD5700 and HD6900 vastly outperforms HD5800. Stop drinking the green kool-aid, Anandtech.
