HD6850 is a bit better than the GTX460.
HD6870 is a (little more) bit better than the HD5850.

So?

HD6850 > GTX460 in EVERY aspect.
HD6870 > HD5850 in EVERY aspect.
HD6870 vs GTX470 is the current competition (from HardOCP).

AMD is in a win-win situation. Consumers are in a win-win situation.

*sips a cup of tea*
Life is good.

I can tell you the EXACT performance of the 5900 series.
October 23, 2010 1:01:32 PM

6850 ($188) is 4% faster than 460 1G, priced $10 more
6870 ($240) is 7% slower than 470, priced $20 less

these are main competitions.

460 768Mb is now priced at $150, and has no competition from AMD. This is a good buy now if you are in that price range.

NV cards seem to have more head room for OC, while AMD cards all supports 3+ displays and draw less powers.

PS. Anandtech actually reviewed a 460 FTW OC version in their official review of 6870/6850 due to the pressure from NV ( they did wrote several paragraph disclaimer saying its not right, but then they turn around used it anyway)

Keep in mind the HD6850 achieved 900mhz without a voltage bump. The HD6870, though, already has an extraordinarily high clockrate of 900mhz and can probably achieve 1-1.05k with a voltage bump.

Pfft, then my GTS 250 Sli is better than a 6850 because my GTS 250 in SLI and better than a single 460.

I'm an AMD fanboy and now i'm so screwed, I was planning to purchase an HD6870, the high-end chip from AMD's next generation GPUs, but NO it's not. The good AMD turned down their iconic naming schemes and the 6870 is now a main stream !!!! a name that represented a GTX480 killer in my head, it's not even close. Too bad AMD, now you're nothing different than the biggest evil, Nvidia. Moreover, the card does present little architictual improvements, too little to be called a next generation card at least. Better Tesseliation !! Anandtech is telling me it's only at mid-level tessilation factors :( . The card is good but maybe i could have considered an overclocked GTX 460 earlier, and please don't tell me the HD6870 can overclock as well, cause it's already clocked very high. I know it consumes 30 watts less than an overclocked GTX460, but electricity is too cheap in my country, which makes little to no difference to me. Both the cards are around the performance of an HD5850, but anandtech is telling me that the older cybress had better shaders and better compute capabilities. I know it might be cheaper to produce than Nvidia's counterpart, but hell i don't care about their profitability, i'm an end user and i only care about performance/price .. and AMD bring almost nothing new according to this measure.

Zen you're...not too bright. The HD6870 is better than the HD5850 in EVERY aspect. Tessellation, power (only idle, really), price, performance, size, efficiency, EVERYTHING.

The HD6970 is the GTX480 killer...or it should be, anyways.

a single gts250 uses more power then a single 6850, so a sli gts250 setup is using alot of power. no dx11 either. costs more then a single 460 and 6850 for slightly more performance im guessing. plus theres the issue that sli doesnt scale the same in every game so in some games the single 460/6850 will be faster.
October 23, 2010 7:38:02 PM

Does anyone have a 6k series card yet that would like to discuss their experience with it?

Such as: Display experience? noise? frame rates? over all game experience? over all card experience?

I'm a nvidia fanboy and I'm seriously considering the AMD 6870.

Actually,the forum was crawling with lots of HD 68xx threads;therefore,i decided to make one which contains both reviews and discussions.Also its stickied on top(At least for now)
Furthermore, the other topic was a "rumor thread" and these cards are now released and available.

October 23, 2010 10:30:09 PM

I doubt the rumors that the Northern Islands will be literally Twice as fast as the previous generation. Maybe 40-50% faster like the ATI 4K - 5K series.

The HD 5xxx and the SI are almost identical in performance. Except the SI scale much better in CF, and use less energy.

The revolutionary GPU performance milestone won't be until 2013 with Nvidia's "Maxwell" cards, which are said to have roughly 16 times the performance of the current Fermi's - the real Crysis killers!

Imagine running Crysis/Warhead on very high/enthusiast at 2560x1600 with 8x AA, maybe even with graphical mods, and get over 100 FPS!

If the 6970s are double the 6870s, and if the new arch is more effective, in DX11 games, add in MLAA, its very possible

If rumors are true, first, were looking at an improved arch, one even moreso than the 68xxs
Then, were looking at 1920 or 2240 shaders, which, as Ive said, scales much better in higher numbers, whether its a simple MC, the 4 wide or other tweaks, or possibly all of the above, it will be a monster, and I dont say this lightly
It may also just be a 1600 shader card, which will still be close to 5970 levels

For one, this is northern islands. Second, my guess is anywhere between 50-100% gains. Second, northern islands has proven to be quite a bit faster than Cypress and the likes. These are only mid range. Look what they have done to the 5770, 5830, and 5750. 2nd, that was a prediction 3 years in advance. For all we know Nvidia might be bought be intel by then. They have NO idea what it will be like, and its 16x CUDA PERFORMANCE PER WATT, not 16x FPS or 16x PERFORMANCE, not even 16x FPS PER WATT.

OT
Heres a nice overview of Fermis arch
http://www.beyond3d.com/content/reviews/55/1

The wriggle room weve seen already shows a +25% improvement, if the 6970 has 1600 shaders
If theyve made better improvements, as the drivers are stating they have for the 69xx cards, and theyre bigger, you can at least double that 25%

You are mistaken in looking at the naming scheme as a means to compare the 2 generations.

The HD 68xx series is the new midrange cards. Comparable to last generations HD 57xx series. The upcoming HD 69xx series will be their new high end cards. The HD 6xxx series already seems to have your "40%-50%" increase over the HD 5xxx series.

I'll grant the new naming scheme has thrown most people off since it seems logical to compare the HD 5870 with the HD 6870 but that's an invalid comparison for the cards themselves. You have to look beyond the card name.

It feels like a number naming mix between the HD 2-5xxx series and the 1xxx series. Just glad they didn't bring back XT, XTX, Pro, PE, GTO, XE, GT crap. Now THAT was confusing.

How long do you think before the launch price of 68xx series will increase? Will it increase before the 69xx series come out?

a b U Graphics card
October 24, 2010 1:09:11 PM

Well...the only reason AMD prices increases with 5xxx was because when they stuck their head up, Nvidia didnt have squat. No competition=higher prices, so they jumped the prices up. AMD has competition time, and while it seems to me 6850>460 and 6870>470, its still relatively close. If AMD jumped prices up by even just $10, it would be bad. So they likely wont raise them. HOWEVER, theres a rumor circulating these Nvidia price drops are only 3 weeks. Maybe to make them not look as good in the beginning. Maybe its wrong. However, if its true, then AMD would likely raise prices as well. AMD has control in a way, if Nvidia lowers prices, they lower them to make their cards look still better, Nvidia raises them, AMD is free to raise them. Somewhat like staying 1 step behind and 3 steps forward.

Why do people keep thinking these are replacements for the 57xx?

It is the 58xx that they replace, they may not over take the 5870 but were no designed to.

The 57xx are being retained the 68xx replaces the 58xx.

i seriously hope the 6750 and 6770 aren't just the 5750/5770 rebranded. wont fit with the generation, the 6670 might have better performance than a 5750. no increase in performance for tessellation. no power adjustments (the 5750 does still give good performance per watt). if they could get the 6770 to compete with the gtx 460 768mb version then it could be good competition.

October 24, 2010 4:53:50 PM

i don't know what prices in the US are like, but in Canada these cards seem like gods. The cheapest GTX 460 1gb is 215$ after sale and rebate and the 6850 is 184$ and it out performs it in virtually every benchmark? Then the 6870 is consistently 30$ cheaper than the closest 5850 and it outperforms it in every respect!
These cards are awesome!

They may not release a 6770/6750 at all, at least not this year.

5770 is sold for $125, its obviously not competing against 460 768MB. More like 450.

I suspect they will release a 6830 to fill $150 market.

CLearly they do not see a point in going to the trouble. The 57xx probably tick all the boxes needed and so fit into their plans as is. Perhaps a bit like how the 8800/9800/gts250 served nvidia all these years. Well sort of like that bar the underhandedness of nvidia's method unless they did just rename the 57xx's.
