Radeon HD 7970 Raw Specs Leaked

If slide leaked on Orb-Hardware is to be believed we GPU consumers are in for a pretty big treat in the next month or so. The slide shown below states that the AMD 7970 will have a default core clock speed of 925MHz and a whopping 3 GB of GDDR5 memory.

It also sports a 3.5 TFLOPs precision floating point. Which would put it well beyond the NVIDIA flagship single GPU solution. The slide states the a ROP count of 32, against an earlier speculated count of 48. This could be because AMD may have delinked ROP clusters from memory bus. The cooler itself is under the trademark AMD black shroud so there is no way to see if it uses the rumored "vapor chamber" as seen in after market solutions.

Looking past all the beastly prowess of this slide one cannot help but think about power draw. The "leaked" slide states the 7970 will have a peak power draw of 300 W and an idle draw of 3 W. We will have to wait for review to see if any of these amazing stats are true.

meh only impressed by the 4.3 billion transistors and the fact that its still 8 pin and 6 pin power plugs. Hopefully it will run well, (that is as long as it doesn't have the same fate as BD).

32 ROP's, so they release new series improve on 20% maybe over 6970, so GTX580 already better than 6970 with good overclocking it pass about 30% over 6970 so it will same performance of 7970.

Did you happen to notice the precision floating point?

wait for reviews, i think another billdozer will come again.

The GPU part of AMD is a COMPLETELY DIFFERENT animal man. This will be no Bulldozer. At worst it will be another 2900. At best it will be the next 5850/70.

right bro, but i am comparing with GTX580, so the 7970 should be have overkill performance over GTX580, that is new series roles.

My crystal balls tell me that this will be 30% faster than the 6970 and 10-15% than the GTX580 in gaming benchmarks.

I think (nothing other then my gut) that the 7970 will devour the 580. It has almost tripple the floating point. But its all rumor. No one knows.

HD6970 has 2.7 TFlops, so it also has almost triple that of the 570. There's no need to point out that it doesn't devour it.

3.5 TFlops is 30% more, and that's exactly the performance increase I think we will be seing. 128 TMU is also 30% more than Cayman so...

On GPGPU tasks Tahiti might trully eat GTX 580 alive though.

That slide isn't from the ACTUAL amd slides dude :toast:

Notice it was the only one with OBR plastered all over it.

Other clues are less than 3w power draw.

It's either bullshit or they including the entire range.


So that floating point stuff is probably the dual GPU card or BS.

And the less than 3w at idle is probably the lowest end card. Even then that's a crazy low number.

I agree man. But I cant help but wonder if this new achtecture will take advantage of the floatingpoint advantage for a change. Hell this thing could be a paper tiger like the 2900.

Of course it rumor. Ive stated that many times. That and its from the ORB as you said so........yeah. Just rumor news man.

I know, but it seems you want to believe it your self.
You covered your self well in terms of posting it as a news story.

No criticisms there :toast:

I'm just playing devil advocate. I'm saying a lot of "IF". IF this or IF that is true. Do I personally believe it? Nope. I believe W1zz and Cadaveca reviews. Until then I don't believe anything.

However I do want the 79xx series to be a success. I want the same for NVIDIA. I like a good fight. Only thing is sadly games hardly take advantage of the 58xx series or the 4xx series by NVIDIA now. Both companies better watch their pricing because its becoming less and less justifiable to drop 500 bucks to play console ports.

Now for our folding buddies I REALLY hope these specs are true.

Still won't be an improvement in folding though ( much of one) AMD/ who ever makes folding needs to get off their arse an do something. : [

There's a how bunch of GPGPU stuff where AMD doesn't do nearly as badly because the developers have taken the time to code with their architecture in mind.

the V7 F@home client works well and gives good ppd on 5800 cards as is:)

i am hopeing 7xxx will be even better though obv

Well apparently I've not been paying attention to the world of folding :laugh:

I thought AMD performance was still abysmal.

i only have a 5850 a 5870 and a gt240 but the ati cards roughly do double the admitedly meager nv one so not great but acceptable

3W idle draw? I can't figure out how that's possible?

well i figure if you take a future view of it, one day this 7xxx gpu having 400-800 shaders and sitting next to 4 BD cores in trinity or the APU after that, then it would make sense to work hard to cut idle power, i mean this core is going to get used in everything from tablets to possibly smartphones media players(poss) ,consoles;) in altered form so pre engineering in such things would make sense if slightly surpriseing

32 ROPs on a 384bit 3GB GDDR5 ram '__'
kinda ties in to it having a 128bit iommu only bus alongside a 256bit memory bus or something

As per clock performance goes up clocks can be set lower and lower. Add in the smaller manufacturing process and it adds up.

Maybe they can have all units turned off except for 1 of the scalar units.
