AMD Radeon HD 6800 Series Specifications Leaked

Specifications of the upcoming Radeon HD 6800 series GPUs have already been doing rounds for the last couple of days, and ChipHell.com finally managed to leak an alleged press-deck of the HD 6800 series that discloses the GPUs' specifications and some key features that AMD will introduce with this generation. What can be said looking at the slides is that AMD seems to have stepped up performance/die-size big time (up to 35% increase in performance per mm²), with some reconfiguring of key components. It also redesigned the GPUs to have up to 100% increase in tessellation performance, new image-quality enhancements, a new video acceleration engine (UVD 3), and a redesigned display IO with 2nd Gen. Eyefinity technology that can let users of standard variants drive up to six displays with a single card.

Specifications of the HD 6870 are: 1120 stream processors, 32 ROPs, 56 TMUs, 256-bit GDDR5 memory interface holding 1 GB, clock speeds of 900/1050(4200) MHz core/memory(effective), and idle/max board power of 19W/151W. For the HD 6850, it's 960 stream processors, 32 ROPs, 48 TMUs, 256-bit GDDR5 memory interface holding 1 GB, clock speeds of 775/1000(4000) MHz, idle/max board power of 19W/127W.

I hope they got drivers ready for 35% increase of speed as they say on first slide!

cadavecaI know...but the default...it's not the same as it was at launch, now. I've seen an increase of a bit over 10c at idle thanks to the clock increase.

Buggalugs, I have been running one monitor for some time now, as i RMA'ed one card a bit over two weeks ago. My idle clocks are 400/900. UVD clocks are 600/1250, and full speed is 900/1250.
I disabled ULPS for my cards and then pressed 'default' in CCC ATI Overdrive - reset clocks back to 157/300. If you're interested?

You altered its settings to result in increased power draw/voltages. If you use it according to its default specifications, idle power draw will be as mentioned. There is no false-marketing on the part of the GPU manufacturer. Both manufacturers rate their idle power draws (and we test to prove) in the same conditions.

I didn't alter any settings. See the post above yours...it was a driver edit that increased the idle clocks. I cannot remember which driver it was, maybe march/april, but there was TONNES of people complaining about it. I haven't modified anything quite intentionally because of all the issues I had. You're more than welcome to come over to my house and see what's up.

I don't even unlock the lock in CCC..no vga overclock here. Yes, I have overclocked my cards, but I use a completely seperate OS for that.

EDIT: You may be right though, BTA, and it's the overclocked bios from XFX that are on my cards causing the issue...but whatever the problem is, it has nothing to do with anything I personally did.

So, if the 6870 is equal or slightly faster than a 5850 (just like i said it would, in other thread), it would be a huge win, if its direct competitor is the GTX 460 1GB (even o/ced).
Which means nvidia could lower the price on the GTX460, nice!
Or, AMD could rise the price of the 6870 lol.

An overclocked 6870 would be on par with a GTX470 or slightly faster (dependeing on overclocking room, of course)

"New and improved image quality features. AA and AF". Is that implying the MLAA mode?

^Atleast there's hope they fixed HD5000s broken AF...

But I think the most interesting detail is the die shot of a Cypress on one of 'em slides.

Yeah, there was a slide refering to a new AA mode...can't remember the specifics though. I want to call it morphing AA or something..morphalogic?

If these specs are accurate, my aging 4850's will be replaced in the next couple of weeks with a pair of 6870s. WOO-HOO!!!

Hey man, i can back you up. When i installed 10.9, defaults went up to 400/900. They started back at 157/300. I dont OC my gfx cards. It was/is a driver issue, perhaps only affects crossfire set ups that way?

Here is to hoping that AMD releases the the "Real Meat & Potatoes" HD 6000 series (6970 & 6990) this week.

Honestly, I do not know, but I do know it's one of the things that I am looking to be "fixed" with these cards.

I'm not really too concerned with performance with these cards. I'm more focused on the outstanding issues that myself and many others are still left dealing with when using the 5-series cards.

5870 is a great card, performance-wise. i've not had a single issue since i sent my second card off for RMA...the idle clock thing is a bit frustrating, but not really an issue, as it solves flicker/artifacting issues. AND I really do think that THAT particular behavior, the new ULPS settings in driver, is what causes the cursor corruption.

See, thing is with many ASUS motherboards, the lower pci-e 16x slot is actually the main slot for dual vgas, but if you plug your monitor into the lower card, you don't get to see any image onscreen until windows boots and loads the vga driver. So the monitor gets plugged into the top card...the slave card...which gets the ULPS clocks of 157/300. The main card, the lower card, gets the 400/900 idle clocks...but doesn't have anything plugged into it, so that particular fix fails, and I'm stil left with cursor corruption, and flickering screens.


Why ASUS does that with the pci-e slots I do not know. I don't even know if that's the actual cause, but it could be...just one of the many possibilities that has come up over the last...damn..almost 13 months now.

I never got increased idle clocks with my 5850's in CrossFire through 10.9's. After 10.7's (maybe), idle clocks increased only when I overclocked the cards.

Well that's it...my cards are overclocked out of the box, so maybe that's the issue..I honestly don't have the slightest. You also edited your 2D clocks, erocker...


All I know is that on a fresh OS I just installed over the weekend, I do not get 157/300 idle clocks, and I have not plugged in a second card, nor anything other than my single 3008WFP.

If I could actually find a cause for these issues, they'd not be important. The biggest problem with all of it is that so many users have problems, and few do not.

Cadaveca, does this occur with single monitor also?

( making sure eyefinity is switched off properly)

I think eyefinity ups the idle clocks due to the flicker problem.

If no, I've no clues as to why it's going up at all D:

Yeah, never connected more than one monitor on the current OS.

Here's a good thread about the idle clock issues, grey screen, flicker:

HD 5XXX, 2D Clocks & Video

Several users edited idle clocks, and fixed issues, and then if i remember correctly, ATI rolled that into the driver...there were other single card, singlegpu users complaining of the higher clocks...some got it lowered by reseting to factory defaults in CCC, others did not.

Anyway, "we" increased clocks @ 2D to fix some issues that I hope aren't a problem in low-power mode with the new cards.

If you look closely, that die shot is of a Barcelona Opteron.

:laugh: I didn't want to step up and say anything, but I kinda wondered about that too..cause it really does look like a quadcore. :laugh:

Good catch.

I stopped editing 2d clocks after the driver that came out that raised them when overclocking. When that driver came out I noticed that while playing video (where I had problems), the clocks would actually raise to "video mode" instead of staying at 157/300 like with previous drivers. Only thing different I did was always disable ULPS mode.
