looks good it true
 
Haven't we seen this before? Pretty much proven to be fake, especially given the 'Steam processors'.
 
it's just random numbers.

i thought the 7000 series is using the same architecture as the 6000 series but at 28nm

Looks in the right ballpark, but undoubtedly just speculation. By the way, that compute power figure implies a ~15% bump in clockspeed in addition to the 108% increase in shaders. Seems unlikely that such a beast could fit into the power envelope for a single card, even on a 28nm process. Most certainly not for <300W.

While it doesn't seem that likely this soon, its certainly possible.

Also remember, the steam processors have 64 per cluster, 64 into 6400 most certainly works, infact, it should be more than obvious :p

Why wasn't the 6970 1600 sp's, very simple, it would have been 25 "clusters" of shaders, while chip design certainly doesn't have to be symmetrical life is generally just "easier" when it is.

When you double up the shaders on a new gen, 25x2 = 50, or, a nice round number a symmetrical core can easily be made up of. So yes 3200 shaders per core and 6400 total in a dual gpu card is VERY possible.

But will the 7990 be the first card they make, that soon, who knows.

I wouldn't be surprised if the next real big gen step doubled up shaders(or came close).

Though if they manage to get some of the front end efficiency from the 6870/50 added to the new shader architecture of the 6970, they might not need to hit double the shaders to come close to doubling the performance, something closer to double a 6870 could be all thats required in terms of shader count.

Of course, if they have the 28nm part working fine, or if they are only making the high end cores at TSMC and therefore only then that would be the only thing they would tape out there.

I'd assume the specs are guessed/fake, but that doesn't mean that aren't a close guess.

bump in base clock, considering its going from 40 to 28nm, and a BAD 40nm, really shouldn't be surprising.

What's the dillio with these Steam processors? Better than the Stream Processors we all know an love?

/coat
 
Rule of thumb for me is AMD card coupled with a non-power-of-2 bus tends to be fake.

Although steampunk graphics cards could be cool.
 
If 7990 Flops specs are true then that would make 7990 about 60 times more powerful than PS3 Cell processor in single precision whose maximum theoretical output is 204.8GFlops
 
Fake - not saying it won't be those specs, tho I think unlikely, but even AMD only have a rough ballpark atm for what their next gen multi GPU would be spec wise.

I love the part about Steam processors. So Valve finally decided to team up with AMD. Good thing AMD are ditching those stream processors, I've got 1536 of them in my pc and I want to drive a screwdriver through my brains cause they are so annoying.... those steam processors are going to make everything better.... o0
