AMD Radeon 7000-Series 28nm (Southern Islands) | 7990 7970 7870 7770 | Discussion

Don't expect so much from the new consoles. I believe it is 2013, right ?

I would figure them for a 28nm GPU with the power of a future 7870/660, performing better than those on PC due to games being coded to the hardware on consoles and lacking the overhead PC systems have. To put it in current terms, I don't think you'll see a GPU any more powerful than a 6970. They only need to push 1920x1080 and don't need to run MSAA, they'll almost certainly be running DX11 on the new Xbox and using FXAA. I wouldn't even be surprised to see them again doing 720P and just upscaling it to 1080P for most games.

I also agree with the post up the page that they won't be using dedicated GPU and CPU, it will be a fusion type chip most likely using shared high speed RAM.

Would be nice to see them throw a 90GB SSD in there as well, but won't happen. They're going to build these things as cheaply as possible.

I hope the hardware review sites will be brave enough to attempt to edit bios on the 'review' versions of their 7950's to bump shaders and clocks to 7970 levels :awe:

I hope so too, if it is a repeat of 6950/6970, I'd like to be able to pick up a few of the cheaper cards and just mod them to 7970 levels.

I'm sure some sites, likely techpowerup, will try the mod on them if the specs when released indicate a closely related cut down card. We may see the 7950 with 1.5GB and the 7970 with 3GB though, that would encourage some buyers to go the 7970 route to get the additional VRAM.

I may be wrong but I thought ROPs are directly tied to memory controllers? The 69XX had 32 ROPs * 32MB module to make 1 GB of memory. The 2 gig models had 64MB modules to make 32 ROPs * 64MB module = 2GB memory cards.

Assuming the memory module size didn't decrease in the next gen card, the 79XX should have minimum 64 ROPs * 32MB module = 2048 memory. From the provided specs, it looks like the modules are 48MB in size. 64 ROPs * 48MB module = 3GB memory.

It is VERY strange that the 7950 is listed as having 60 ROPs (compared to 64 of 7970) and still maintains 3GB of memory. Something tells me they're fudging the specs there, as a portion of memory is actually not physically addressable.

Except that you can count the number of memory modules on the leaked card. It is not 256-bit.

 

[MrK6]

Shouldn't it be 48 ROPs per the 384-bit bus? And to get 3GB they'll use 64MB modules? Or 32MB modules if they want 1.5GB? VR-zone picked up on that, they're usually pretty knowledgeable. I wonder if it's just people conning these FUD sites like OBR; I hope he didn't pay too much for the picture D:

So long as they "START" on a 28nm designed GPU then the next gen consoles will at least have an extra few years of tech in them as the GPU shrinks over the lifespan of the consol..

If they start on 40nm Designed chips then these consoles are going to be outdated very quickly....

All indication is they are taking a 40nm designed GPU's (HD6750) shrinking it to 28nm and popping it into the next xbox and play station consoles to pair up with a 4 core 45nm IBM CPU that they are shrinking to 32nm ...

So the next gen consoles will be almost 5 years behind in technology VS whats in a PC's before they even hit the shelves... VERY sad day for PC Gaming

Unlike the last gen consoles that were only 1 year behind, but still has managed to hold back advancements in graphics and game dynamics from limited hardware.

I wouldn't be surprised. Sony already voiced its opinion that the PS3 was way too expensive to manufacture which resulted in them losing too much $ for a long period of time before actually breaking even. The system initially cost around $900 and even by the end of 2009, it was still about $336 to produce. So I don't expect that next generation of consoles will only be 1 generation behind the PC. If they put anything as fast as an HD6870 in there, I'll be ecstatic!! By the end of 2013, we'll already be on Kepler and HD7970 refreshes I bet. You'd think that the next generation of consoles should have at least a 28nm HD7870 in there by end of 2013, right ?

Wasn't this due to the complete farce that is Cell though? Didn't Sony spend billions on its R&D thinking that it would also act as a graphics solution only to find that it couldn't do the job at the last minute?

IMO, MS or Sony should just use a nice fat GCN core (say between 1000-2000 shaders) and that's it. Hopefully it would be flexible enough to run graphics and everything a cpu would? Stuff 2GB of RAM in there, a 1TB HD (when supply is reasonable again) and bam you have a console that can last years.

 

[Grooveriding]

Multiple early rumours and past history points to Microsoft using an AMD designed GPU for the next Xbox. Just don't expect so much from the consoles.

I think we'll see 7870 performance with 1-2GB RAM and a fusion chip with CPU/GPU on board. That is enough to give the console crowd some graphics that will make them swoon, but still budget enough to make them cheap to produce.

Console players have proven they are just fine with upscaled 720p and 30FPS. So even an upgrade like that, heck they could use a 7770, would be enough to satisfy the console players.

I would be shocked if a fusion chip comes out within the next 3 years that will have GPU performance equal to an hd7970 or hd7870. I'm sure that you're right MS will use AMD for it's next xbox GPU, but I don't think the performance is anywhere close to being high enough for a next generation console with current or foreseeable fusion parts.

But on the thread's subject, looks like AMD is now officially shipping 28nm GPU's. http://techreport.com/discussions.x/22170 I do hope that you guys are right and it is in fact the high end GPU's. It will be somewhat of a letdown if the Jan. 9th release ends up being just a specs sheet or paper launch. Regardless, good news all around that 28nm GPU's are now officially on their way to AIB's.

I thought part of the reason for not using "standard" off the shelf components was to combat piracy? The PS3 did last a while before it was hacked.

 

[Olikan]

some new images....

 

[Soccerman06]

lol at the blocked out areas...

I still find it funny people say the ps4 will use IBM cpu...

 

[Screech]

BREAKING NEWS: recent reports indicated that the 7970 will be at least 2.5% faster than the 6970! (from blocked out area )

Man, I wish the NDA would lift but meh, it is what it is.

To get you to go to the site and drive traffic to it. I'm gonna pass. I have no basis to judge whether these are real or not anyway. I can wait a couple weeks for the launch and reviews.

Missing the x-mas holiday is terribad. Are they pagans Satanists? lol

 

[tviceman]

Nice, it looks like idle power really is <= 3 watts. That is pretty great but I wonder if it needs an integrated GPU to achieve this. But I can't say I'm impressed with the tessellation performance. At a glance it looks like it will just match the gtx580 tessellation at best.

 

[MrK6]

Hosted!

3.5x tessallation performance is awesome, looks like they fixed the scaling. Also, 50-70&#37; performance improvement in games is awesome. Even if that's best case scenario, 30-40% is still great, especially considering the minor clock speed boost, and puts it well ahead of even the GTX 580.

And just kidding, it's evidently fake:

Dec 22nd ?

Even if they were real, what's the utility of these slides? Relative performance at what resolution? Visual settings? There's no context to form actual useful conclusions. They're so patently edited and framed to present the rosiest picture, usually by omitting needed info. It's kinda insulting.

 

[hdfxst]

i don't know if these slides were posted but it looks like the dual bios switch is there http://translate.google.com/transla...yanin-en-guclu-ve-en-gelismis-ekran-karti.htm

here's the whole slide deck if you can read them http://3.bp.blogspot.com/-F-4_jGKGLXU/TupC4-IPznI/AAAAAAAABjk/q-g8HFo-Xy8/s1600/slides.png

Even if extremely limited it would be great to see some actual benchmarks from a Dec 22nd launch.

I'll have newegg up at work that day. If it turns out to be true, I'll pay the extra shipping to get it before christmas. Fingers crossed...
