One thing the authors did not emphasize is the improved Crossfire scaling on the 6870, compared to the 5-series Radeons... based on AVP, at least, the 6870's multi-GPU scaling is as good, or better than, SLI'd-460's... considering that was one of the major selling points of the 460 (for me, at least) that could be pretty bad news for Nvidia. Of course, maybe scaling isn't as good in other games. Would definitely be nice to see an article on the subject soon... This also bodes well for the new 6970, or 6870X2 or whatever they call it with the new nomenclature.
Hope some of these cards make it into the next SBM.
 
Why would you run these benchmarks without the GTX460 768? That is the part the 6850 is targeting!
6870 v GTX460 1G
6850 v GTX460 768
That's the most important part of these benchmarks.
Why are people getting hung up on the naming scheme?
I dont buy a GFX card by numbers I buy it on performance/price after looking at bench's.
 
[citation][nom]scrumworks[/nom]You seemingly want to talk more about nvidia and their magnificent Fermi than AMD. The whole introduction was almost concentrated on downplaying AMD and telling "Nvidia's Answers". It's like you wanted to review another Fermi but were forced to review a new Radeon.[/citation]

You never disappoint, sir.

Truly, I can always trust you to spin anything and everything into an AMD-hating article, scrum. No matter how positive for AMD it might be, you can rustle up a conspiracy. 😀

Because it's better than that.
The 6850 is plenty good enough to go up against the 460 1GB, and judging by Nvidia's pricing response they're worried about it, too.

Both Anandtech and Guu3D have crossfire reviews up. You can check them out if you're interested.

A magnificent specimen... Please study closely fanboys.
 
I know a lot of my uninformed friends are gonna jump at this thinking 6850 = "5850 successor"... Good for me I read up on Toms, but what about the other poor souls

Still, awesome..Awesome cards for the midrange scene!
 
I didn't expect anything big to come out of this refresh. The next biggest thing should be the Radeon 7xxxx series, that's where it's rumored to have a completely redeisgned chip that will be based on the 28nm die support DirectX 11.1.
 
Results speak for them selves: HD6850 > GTX460 1GB, HD6870 > GTX470. Wins in power consumption and noise tests are substantial for AMD. What you forgot to mention that HD6800 die size is almost 50% smaller than GTX460 which makes everything a lot more impressive.
 
This is similar to 2 years back when one could get a great card like the 4890 for $200. This is simply great. I am waiting for the high end Radeons, but I am also waiting the fully featured GF104 card, which will make the competition even fiercer.
 
"These are the cards that lead AMD’s charge into the realm of stereoscopic 3D, the cards that make six-monitor Eyefinity a much more accessible possibility, the cards that add the first post-processing based AA mode, the cards that bring AMD’s tessellation performance much closer to the GeForce-based competition."

That was the best part of the review, at 180.00$ for the 6850 and 240.00$ for the 6870 you are getting excellent performance + improvements at a great price . I actually thought they would cost at least 20.00/30.00$ more but I guess I was wrong. Bravo to AMD, I can't wait for the 69xx series to drop.

On the other hand what I didn't like was the fact that the 6870 seems to be a 5850 with a higher clock speed. Of course not all numbers match when it comes to the spec's but that is basically what I see here.
 
Something fishy in the last "average" performance graph. HD6850 practically always wins GTX460 when the resolution is cranced up. Lower resolutions shouldn't count!!!!

It won't be 6870x2 by any means because 6870x2 means nearly twice the 6870 performance which will still be comparable to 6970 (guessing). Anyway, it is rumored that the beast Antilles will be named Radeon 6990.

Not really. the last performance graph uses the common high-resolution of 1920x1080.

Not a lot of folks out there with 30" 2560x1600 displays, Cynergy. :)
 
Although I'm not happy with the deceptive new names, I'm glad AMD finally has gotten around to focusing on some of the smaller details, like basic 3DTV support. It looks like even the XFire efficiency is pretty decent.

If it wasn't for the fact I picked up a GTX 460 1GB for $180 on sale two months ago, and already invested in NVidia 3D Vision Glasses&Monitor, I'd totally be all over these new ATI cards. I always thought the 5870 was too hot/loud anyways.
 


So you are saying that 1680x 1050 doesn't count?

The 6850 is basically as fast as the 460 1Gb, it depends on the game..

I say they are pretty much equal...

 
how can average be less than min value in the above graph,is it relative to what?
 
I don't know if I made a mistake in buying a 768mb gtx460
I can overclock it pretty far (920mhz) but damn-it I should have waited a month! Stupid canadian pricing tempted me - i bought the thing for only $180 to my door back when it was 220 and 1gb was 250.
 
Even though I had no inside info, a careful ear to the rumor mill and the two or three leaks earlier from other places left me quite prepared for these results. SO GTX 470 and 6870 are neck and neck for performance, but 6870 has the advantage in noise, heat, cost, power consumption, and a few minor (to me) features. Seems pretty clear.
It does seem like you guys were drug kicking and screaming to the same conclusion though? Maybe it's my imagination but that's the impression I got?
Anyway, I'm off to find some further game benchmarks... OH, a BIG thanks for the Civ V bench.

Kicking and screaming... that might be a little over the top, but yeah, if you mean we sound like we're pretty tired of getting constant calls from PR staff trying to convince us that everything is changing at the last minute, and that what everyone else is saying is wrong.

Yeah, we're tired of that. But the conclusion? the conclusion is inevitable, it's where the data leads. Certainly happy to get there, just unhappy with the way we were pushed around on the way.

...I think what you meant to say was "This is what happens when a company comes late to the show with less-than-amazing hardware."

Not only were their fermi cards so late, but they were a bit of a letdown as well (with the exception of the 460). And now they are finding themselves falling behind even more with this new pressure from AMD. That's what happens when you end up coming late to as big a show as this.
