AMD released its fourth beta of the ATI Stream SDK version 2.0, that provides the first complete OpenCL development platform. The release is certified to be fully compliant with OpenCL 1.0 by, the Khronos Group. A wide range of AMD GPUs as well as any x86 multi-core CPU supporting SSE3 instruction set are supported. For more information on this release, and to download, visit this page.
An interesting discovery by TechConnect Magazine shows that in these OpenCL drivers, are identifiers for a yet to be announced "Radeon HD 5900 Series", with the device IDs 689C and 689D, both marked under "Evergreen", like other members of the Evergreen family, such as Radeon HD 5700 and Radeon HD 5800 series. The most plausible explanation for "Radeon HD 5900 Series" could be that it is the name of the graphics cards based on the Hemlock GPU architecture, which pairs two Cypress GPUs onto one board. The driver also gives away device IDs, if not product names of GPUs based on the upcoming entry-level Redwood and Cedar GPUs.

HD 5900 Series ??? device IDs 689C = x2 and 689D = x3 ???
5870x3 WOW
Or Its should be.......:cool:
5870x2 = 689C
5850x2 = 689D
5870x3 WOW

5870x2 = 689C
5850x2 = 689D
I knew ATI would bust a 900 :D
by: saikamaldossNo. 689C = HD 5950, 689D = HD 5970.

HD 5900 Twice is powerful as HD 5800, which in turn is twice as powerful as HD 5700.
by: btarunrHow do you know this?
No. 689C = HD 5950, 689D = HD 5970.

It would be absolutely awesome, if true.
Because 2 of the same gpu on on card = twice as powerful :D

Because 2 of the same gpu on on card = twice as powerful :D
That is, if there is support for 2 GPUs from the application. Unless it's no longer 'internal crossfire' and is actually 2 GPU cores, with a 512-Bit Memory bus, and 3600 shaders etc, not just 2 cards on one.
Ha, i'm glad i didn't bought a 5800, now i'll save for one of those. :P
by: pantherx12Hunh, what is really interesting for me is redwood and cedar..... :laugh:

Hemlock will never be for sure and cypress must get to $100.00-$130.00 so I can buy two and crossfire! :laugh:
July of the next year maybe ? :toast:

Well, HD 5970 is HD 5870 "X2", and HD 5950 is HD 5850 "X2".
Whutt........... upgrade soon.....:eek:

sweet :)
Good -- "5970" is a lot better than "5870X2". Always hated the extra bit at the end.
meybe they went the way of the Pentium Dual Core aka 2 cpus on one die instead of 2 cores on a die hehe with the HD 5900 chips
by: wiakHell, even that would be an improvement over the current "sticking two chips on one board" design.

well I see it easily, it says HD5900, meaning either there are faster single GPU cards than the current HD5870 coming(which would be a real suprise) or the HD5900 series will be comprised of dual gpu cards, which would make more since, this could also mean that ATI managed to create the first true dual gpu with 2 gpu's combined into one chip but this might be impossible due to the high tdp of the R870

i'm guessing they're simply renaming because they aren't planning a fab process shrink and want to use up the 57xx and 59xx numbering becuase of that. afterall, the 3xxx series didn't have a shrink and a 37xx, 39xx, or even 3790 (although 3xxx was almost just a die shrink itself :laugh:).
now the only room to grow would be 5890 and/or 5990...
Suddenly ATi's naming scheme has gone from frustrating to fantastic.
If there's the 5750, 5770, (5790,) 5850, 5870, (5890,) 5950, 5970 (5990) and they are all progressively more powerful, it's great naming.
No doubt the 5x90's will come out in time, those will only fit in nicely if 5790 < 5850 and 5890 < 5950 and 5990 = nVidia pawned.;)

by: inferKNOXgood point. it was confusing when 4770 beat 4830 and was nearly as fast as 4850 in some cases.

oh ya, there are pictures of the hemlock out there, it's definately not two gpu cores on one die. it's an X2.
I've never ran ATI Stream, am I missing anything here?

Yeah, I saw that too and was/am hoping it ain't true:

Erm ... there's three 5700's in that list.
So what is the third one?? 5730 or 5790? 5790 would make sense and would slot in nicely in the performance gap between 5770 & 5850.

appart from all those new GPU's you're missing one important point for me and any other consumer running ati gpu's
Finnally the got something maybe USEFULL before nvidia,
I hated ATI for my x1900 because it was one of the best cards with my 9800 Pro back in the days but they promised to accelerate Video, or codec to be loaded to the x1900 which worked but was weak....
then i went with my hd4650 in favor of an ultra cheap HD3650 because my 8600 GT died on me.
Hell was i frustrated with HDTV Videos and no CUDA support for ATI, ok DXVA running fast like Hell but not comparabel with Cuda as it was multi purpos for anything....
and now ati supports opencl, maybe we will see NOW some GGPU Software and please with WIDE support as it is one point to spread tec!

From this list it seems there are going to be a lot of Cedars and Redwoods? A Radeon HD 5690, 5670, 5650, 5630 and a Radeon HD 5570, 5550, 5350 and 5350? These SKUs seems to be a bit excessive?
Why there is no support for hd2000/3000?
