R700 Inter-GPU Connection Discussion

What about ambient occlusion ? For next game ?

 

And here it is:

 

Man, that's a terrible packaging job.



And now i know what Digi's phallus in bubble wrap looks like.

 

Any information about the NDA date for this card?

 

AFAIK, AMD went for a preview with a couple of websites on the 14th of July and then a launch 2/3 weeks later.

 

I hope something leaks out soon.

I really want it to be something special - they figured out a way of, idk, violating the space-time continuum to transfer infinity data to and from each die, every ns.

But I know that it's just going to be silly little bus with a few GB/s...

 

Lol I kind of hope that if someone figured that out they'd have the perspective to know that GPUs - and indeed computation and the universe as we know it - would be fundamentally altered and there would be much more significant consequences than faster gaming

 

Nonsense!

 

See, now that's just crazy talk right there.

 

... alright I'll just go back to making pretty pictures then

 

Exactly

 

R700 up to 80 % Faster than GeForce GTX 280

 

Interesting. Is this the first we've heard of a 4850x2 to go along with a 4870x2 ?

 

Confucious say, "Man who take 'up to' at face value before release probably needs someone else to cut his food for him."


The claim of 50% "on average" is much more interesting looking, but there are no doubt some unspoken caveats there as well --like, "once we've got the CrossFire profile for a particular game released". That's if we're lucky and it doesn't mean "at 8xaa 2560x1600".

 

Guessing at 4800x2 performance is certainly likely to be a bit more accurate than guessing at the performance of a new unknown part. Is anyone really expecting it to be significantly better than 4870s in crossfire?

 

There were some claims of it being up to 15% better than crossfired cards (on what, I don't know), but I don't know if everything else about the cards such as clocks and memory capacity would be equivalent.

 

Does anyone have a good breakdown of just how much bandwidth was being used by crossfire setups in the past? I know the cards are a good deal faster but I don't remember as much of a performance hit when using mobos with less than 16x/16x PCIe configurations.

Could it just be a matter of the interconnect actually having enough bandwidth to support two chips on top of slightly lower latency? With how ATI has been mapping memory on the cards it wouldn't really surprise me if they were sharing memory. I'd think a pair of x2 boards would saturate things fast. Might also explain why they seem to have beefed up the cache a bit.

 

Just about everyone, I think.
