Consumer rebadges of old cards (77xx, 78xx) based on the 6000-series VLIW4 arch. coming out first, new 79xx series cards based on totally new architecture coming out Q4'11 or Q1'12.

Also a 7990 "New Zealand" dual gpu coming spring next year.
28nm process and later shrink to 22 or 20 which means less power consumption, potentially smaller cards, more performance per dollar.

It's still up in the air whether the new generation from AMD will be introduced in 3rd quarter or 4th quarter. It could be either at this point.


Consumer rebadges of old cards (77xx, 78xx) based on the 6000-series VLIW4 arch.
Even if the VLIW4 microarchitecture may be reused, it won't be fair to call it rebadging. You can only call it that if they take the 40 nm Cayman, and let it remain 40 nm, yet call it 78x0 or something like that.

But this time, hopefully everything will be shrunk by two halfnodes down to 28 nm, in this case they will be entirely new chips.

That's exactly what happened with 6750 and 6770 cards :|

They are literally 5750 and 5770 Juniper chips rebranded as a 6xxx series card, only the BIOS is different.

I know. But AMD was locked at the 40 nm process at that time.
Barts was 1120 shaders.
Turks was 480 shaders.
They needed something inbetween. Instead of redesigning a new 800 shader asic at 40 nm, they reused their current chip. Redesigning new chips at the same shader numbers would waste millions of dollars.


This time it's different, they are no longer locked at 40 nm, and you know that.

Well AMD/ATI can use 28nm HPL (low power) process thats ready to go. Nvidia have to wait for the 28nm HP process which will knock them to at least 1st Quarter next year till they have ANYTHING! Sept is my guess at ATI 7 series, weather the 7950/7970 will be there is another question. As someone said, they may be going to 28nm HP also with this but my guess is you'll have a full range on 28nm HPL and then a refresh when Nvidia release there montrosity onto unsuspecting victims....mmm... customers....... which will also use the same process as nvidia's with the fix's/mods they maked in the quarter that AMD owns the market, i.e, christmas and NY

Explanation of 28HP and all the other stuff here... mind you, its charlie Tongue

Nothing besides rumors, expectations are only based on the fact 28nm lithography allows for 30% more transistors.
Biggest news bomb is the fact they are abandoning VLIW based stream architecture and moving onto SIMD instead of VLIW3.

Most sources incl. donanimhaber & chinese leaks confirm what m3sSh3aD posted, the powerful 79xx series GPUs will arrive Q1 2012 at the earliest. Hoping Nvidia will release their Kepler arch. fast to pressure AMD into an earlier release.

Consumer level GPUs (76-78xx) are slated to arrive much earlier, Q3/4 this year.
Mobility radeon's (laptop) will be among the first

Mobility chips have traditionally always been slower to release. It goes like this:
Desktop cards first
Mobile cards second
Workstation cards last

That's not what m3sSh3aD meant. He's guessing that they will release the entire top to bottom range in Q3/Q4 (using slightly inferior manufacturing process, but available earlier).

Looked long and hard to find confirmation on whether anything would come out Q3/4 this year,
only to find potential problems with the manuf. process of 28nm chips.

http://lenzfire.com/2011/07/nvidia-kepler-2012-and-maxwell-2014-release-date-official-2-84329/

It seems Kepler is pushed to 2012 earliest, since AMD uses the same company (TSMC) that could mean delays. Other sites also report the problem with making 28nm chips.

Sucks for miners, things are already getting pretty unprofitable in the short term with current hardware price/performance + electr. costs.

I found this news article which was just released a few hours ago.

http://www.pcper.com/news/Graphics-Cards/AMD-CFO-States-They-Will-Have-28-Nano-meter-GPUs-Out-Year
Quote from: Thomas Seifert, AMD CFO
“We also passed several critical milestones in the second quarter as we prepare our next-generation 28-nanometer graphics family. We have working silicon in-house and remain on track to deliver the first members of what we expect will be another industry-leading GPU family to market later this year.
We expect to be at the forefront of the GPU industry's transition to 28-nanometer.”

Hoping he's right and they beat Nvidia to 28nm this year & it's not just marketing

Not necessarily so, what you fear is completely unfounded. Traditionally, ATI/AMD has always been better than nvidia at utilizing newer manufacturing processes.

HD 4770 was built on 40 nm. It was released in April 2009.
GT 240 was built on 40 nm. It was released in November 2009.
ATI was 7 months ahead.

HD 5870 was released September 2009.
Gtx 480 was released March 2010.
ATI was 6 months ahead.

HD 4870 was 55 nm, released June 2008.
Gtx 285 was 55 nm, released January 2009.
ATI was 7 months ahead.

Do you see a pattern? The two companies specializes in different competencies. It would be unwise to attribute some of nvidia's weaknesses to the ATI team.

AMD had a momentarily weakness when TSMC cancelled the 32 nm process. This incident screwed ATI over because their strength was taken from them and they were trapped on 40 nm.
But this time, it's back to business as usual.


Looked long and hard to find confirmation on whether anything would come out Q3/4 this year,
only to find potential problems with the manuf. process of 28nm chips.
The SI tapeout happened in February

Like I said, ATI tends to be more competent on newer processes, so nvidia's problems may not necessarily be ATI's problems.

you missed my point. that's the 28nm HP, 28nm hpl is ready to go. people make chips on it now. weather it has the.power for top end cards I'm guessing not but we can live in hope and a nice revision in January would lower the cost of the first revision cards. but I guess 79xx at q1 2012. 78xx and below will be here soon....

No clue what hashing speeds would be but I assume it would be inefficient at the brand new price point. What will really be interesting is the price drop in the earlier series and what new opportunities we might have with currently inefficient cards.

Bad news, interview of TSMC CEO confirmed 28nm chips will be delayed because AMD/Nvidia have canceled their major orders for this year.
28nm chips will only account for some 1% of their revenues by end of Q4 this year

http://seekingalpha.com/article/282679-taiwan-semiconductor-manufacturing-ceo-discusses-q2-2011-results-earnings-call-transcript?part=qanda

Quote
You mentioned that 28-nanometer is taking a bit longer. Can you kind of describe if that is relate to just maturity of the process? Was it related to just customer not ramping the design that they have and you were previously, maybe previously expect them to ramp. And finally, how much of yourself do you expect to come with 28-nanometer for the second half or for the fourth quarter of this year?

Quote from: TSMC
The delay of 28-nanometer is not due to their quality issue, actually we have regular tape out and it is unplanned. The July ramping is mainly because of softening economy for our customers, so customers delayed a tape out to us. So therefore, the 28-nanometer revenue contribution by the end of fourth quarter this year will be roughly above 1% of our total wafer revenue.

Doesn't sound too promising for a 2011 launch

Where does it say this?  Huh


1% could still be a lot of wafers. Do you have any data of how many of their existing customers are still utilizing their 65 nm process for example?
It was never a big secret that high end videocards have always been low volume.

How can you be sure this has any relevance to AMD at all? Southern Islands taped out already back in February...

From what I read, in Q2

http://www.xbitlabs.com/news/other/display/20110422111145_AMD_Expects_Two_28nm_Tape_Outs_This_Quarter.html

Quote
AMD Anticipates to Tape-Out First 28nm Chips in Q2 2011

"We expect several 28nm tape-outs during the current quarter. We balance our loading according to risk performance and price. But we also said that there is, of course, a natural incentive for us at this point to work closely with Globalfoundries, and that is, of course, something we continue to do," said Thomas Seifert, interim chief executive officer of AMD and chief financial officer.

Also, AMD and Nvidia account for nearly all of TSMC's business.

I'm just posting the news as they come because the delays are relevant for mining

http://uptonews.com/07/tsmc-admits-28nm-ramp-up-is-taking-longer-than-expected.html

Quote
A little more than two weeks ago, the foundry stated their 28nm fabrication process is on track to enter mass production in the fourth quarter of 2011 and that it is expected to account for 2-3% of its total wafer sales in the last quarter of the year.

However, it now seems like this figure was exaggerated, and that chip sales based on this node will hardly go over 1%.

Quote
TSMC hasn’t revealed any information regarding the customers that are expected to mass produce chips based on this advanced fabrication node in 2011, but both AMD and Nvidia rely on this process to build their next-generation graphics cards.
