"AMD Radeon’s Next Gen Southern Island GPU’s release dates have been leaked on Yahoo Finance Forum. According to the release dates, AMD would be launching its High End HD7000 Series graphics cards in January 2012 while the Mobile Discrete chips would be launched in next month in December 2011, AMD also plans to launch a Dual Chip flagship card codenamed HD7990 in March 2012.

The High End HD7900 Series would consist of the HD7970 (Tahiti XT) and HD7950 (Tahiti Pro) Graphic cards which would feature the new GNC (Graphics Next Core) Architecture. These higher end models would use the XDR2 memory featuring double the memory bandwidth against GDDR5 – 6Gbit/s (GDDR5) Vs 12.8Gbit/s (XDR2). The use of XDR2 and 28nm design would also lower the total power consumption by 30% resulting in a much cooler and efficient GPU design. Also, XDR2 memory has been confirmed by AMD’s official Twitter Account:

AMD would also equip its new Liquid Chamber Cooling design with its High End Series which also include the Dual Chip HD7990 which is based on two HD7970 Cores. A few slides detail the new Liquid Chamber Cooling design and Technology, For Complete details head over to TechPowerup.

The Leaked release dates also show the IGP’s which would be used in AMD’s Upcoming Trinity APU’s (Accelerated Processing Units). These include the Devastator based HD7450/HD7550 which would launch in Q2 2012 along with Trinity Launch and will feature the VLIW4 Architecture.

Release dates of the Mid End Card such as the Thames XT/Pro based HD7850/7870 are yet unknown but they are most likely to be die shrinks of past gen HD6900 Series and would feature the VLIW4 Architecture. http://videocardz.com/29696/amd-hd7...mory-and-new-liquid-chamber-cooling-confirmed

My guess on the specs

Going by the 100% jump in performance from HD4870(55nm) to HD5870(40nm) i would say the new HD7970(28nm) will be around 100% Faster then HD6970(40nm) and slightly faster than two of them in crossfire

that would be seriously insane-in-the-membrane performance at that price and would kill any hopes of ever selling another 6990. which is why i think the timeline isn't realistic.

 

[videoclone]

The HD6990 costs AMD and the add in board companies allot to make, they dont sell many of them and so if they can replace it with a more profitable part sooner rather then later thats probably a good thing!

They could be trying to release bulldozer with a bang and have both a New GPU and New CPU out at the same time so people can match up both parts for an AMD powerhouse system maybe!

 

[Blitzvogel]

All the specs are certainly plausible. Remember the "good 'ol days" when the 4850/4870 had a mind blowing 800 SPs!

I don't think the chip would be clocked so high, probably around 900 MHz default. The memory clock seems high too, but unless AMD goes with a larger bus, they need to keep up by increasing that memory speed using lower process RAM modules.

 

[happy medium]

I think the 7970 will be as fast as 2 6950's in crossfire and have 2816 sp's. I believe it will include some cpu/gpu like features kinda like the fermi chips and with better tessalators. Core clocks around 850.

 

[Grooveriding]

I don't think we'll see the new AMD 7970 until September. And while it may release before nvidia has anything ready on 28nm, I certainly hope nvidia does not screw the pooch again and have nothing ready for months like they did at the 5870's launch.

I prefer the usual situation of both of them releasing new cards within a few weeks of one another so if one ends up being far and away better than the other I can go with that card.

When AMD releases on 28nm, if we have nothing from nvidia but announcements of announcements and no actual confirmed release date, it's going to be a sorry state of affairs for nvidia again. I don't think they'll screw up that badly twice and do it consecutively at that. It put a hurting on them with 40nm.

Buyers in the market for the latest high end will remember the history of the 5870's launch and the seven months it took to see the 480 and just buy AMD at the get go if nvidia has no release date announced.

Hopefully we see the single gpu halo from AMD at the start of the fall.

My guess is that these will be the last DX11 cards.

DX9 lasted for 2.5 years. DX10 ~2.5 years. I'm guessing DX12 in Summer '12.

 

[happy medium]

I don't think we will see the new 7970 cards untill somewhere after Halloween.
I do believe however we will see a mid range AMD 28nm gpu sometime in August.

 

[blastingcap]

4770 = 40nm pipe cleaner GPU to make sure 40nm works

???? = 28nm pipe cleaner GPU to make sure 28nm works

Whatever ???? is, it won't be the 7970. It will probably be in the 6850 or 6870 speed range, with lower power draws, and MAYBE more features other than VLIW4. Like more RAM or something. But don't hold your breath.

 

[OCGuy]

100% jump from 55nm to 40nm? Don't remember that....

No matter what, just hearing rumors means that 28nm is going well, and we can all use some good news in that regard

I am with other people in this thread in saying that a mid-range will be released well before the 7970.

 

[cusideabelincoln]

AMD will probably want to keep die size in check. As such I don't expect to see any bigger performance jump between the 6970 to 7970 as we saw from the 4870 to 5870 - since the 4800 to 5800 was the last jump in high end in correlation with a node shrink. Unless, of course, they manage to make some nice gains in performance efficiency.

We're going to see a really huge jump in performance per watt, though, much like we saw from 4800 to 5800 where the 5800 cards had lower power draw than the 4800 cards.

unless they bet on 28nm and go with the high performance card first, to deliver a one-two punch with bulldozer.

if bulldozer lives up to all the hype, and the new gpu comes out at the same time late this summer or early fall, I, for one, am sold on both.

I have a feeling that isnt how it is going to turn out, but hey, you never know.

 

[3DVagabond]

I think we might not see a 2x shader/performance increase with the 7000 series. I think the 7000 will have more gpgpu capabilities, dp, etc... They'll need to come out with new fire GL/pro cards to try and compete with Fermi @ 28nm or they'll get trounced.

 

[Spikesoldier]

absolutely, anything is possible. but wouldnt one expect this behavior out of the underdog?

 

[StrangerGuy]

My bet is we get a 28nm VLIW4 "6930" card first, and the whole 7 series will be completely VLIW4.

:thumbsup: I agree.

 

[santz]

wow, we are jumping on shadows of shadows already

 

[CFP]

Haha we will not be seeing a 100% performance increase.

 

[Skurge]

Haha we will not be seeing a 100% performance increase.

what makes you say that?

 

[Silverforce11]

Whats the news on TSMC 28nm production capability? GF isn't due for 28nm ramping til 2012.

 

[AtenRa]

4870/90 to 5870 was double the Stream Processors (100&#37 and ~double the transistor count (959M vs 2154M) but only ~50% more performance.

http://www.techpowerup.com/reviews/ATI/Radeon_HD_5870/30.html

We always get double the transistor count and ~50% more performance with a process shrink.

 

[DarkKnightDude]

Good thing I waited to upgrade to my 5750. I'll probably get 7870 or whatever they have in mind.

Will the jump to 28nm mean less power consumption and temps? My knowledge on gpus sin't all that good.

 

[VirtualLarry]

Here's hoping that they put back FP64 support into their 28nm chips, since they removed it from the second batch of 40nm chips.

Temperature has nothing to do with process. Having a smaller process, bigger process, more, fewer transistors, higher, lower clockspeeds don't matter when it comes to temperatures. The heatsink and fan is the main determining factor.

In terms of power, it means less power use at a set level of performance.
That doesn't mean the top end GPU uses less power, it means it uses an amount of power which could be higher, lower or equal to the previous top GPU, but it runs faster.

28nm = more transistors in a given die space, more performance at a given price point.
