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 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.
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)
But I think the most interesting detail is the die shot of a Cypress on one of 'em slides.
Check this page: www.compusa.com/applications/SearchTools/item-details.asp?EdpNo=6799926&CatId=3585 according to that the 6870 is gonna be around $270. It lands in HD5830/GTX460 zone.
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.
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.
( 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:
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.
Good catch.
:D
