So what should we expect from Ati's r800 and hd5800 series?

Well there seems to a lot of speculation that these could be dual core gpu's, which if true could really be something. The chip has been codenamed the 'Lil Dragon' and will be made on a 40nm process. Each processor is expected to have 1000 shaders so if rumours about a dual core GPU are true that would be 2000 in total. If the Dual Core claim is true it could remove the problems that can be entailed with Crossfire and SLi. Lastly, the power consumption has been reduced probable due to reduction in size.

So 2009 could be interesting year, a card that could maybe play Crysis easily with everything maxed out

Edit: Apologies typo, the title should be Ati r800 GPU

Every bloody chip since G80 has been rumoured to be 'dual core' at some point or another. No. It doesn't even make sense since the chips are essentially made up of lots of very small cores anyway!

</rant>
 
I think ati are moving in the right direction for dual gpu as the 4870x2 moved on the technology from the 3870x2. I don't think anything is gonna play crisis well the more power that gets added does not seem to give the gains expected and tbh the games gonna be really old by the time this does happen and nobody will really care.
 
I don't see why they would bother with dual core - it just seems a lot of R&D money when Crossfire on a single card works so well.

Yeh a bit like Far Cry was as that took a while before it could be played at max
 
Why have dual core when you can punch twice as many stream procs into one chip and have essentially the same thing? Is it yields or something?

I don't think it's that simple. The stream processors can only compute certain things and you won't necessarily get twice as much performance by simply doubling the stream processor count.

Ideally, what you want with a multi-gpu card, is something that is completely transparent, i.e. the card should behave as if it is a single-gpu solution at a hardware level and not driver level (like it is with crossfire/sli).
 
Dual cores would be great, if they worked.
CPU's don't and SO FAR GPU's only do so in a stressful and half assed way via Xfire and SLI.
If every single one of your games doesn't support Xfire/SLI then you're buying a GPU, and a big case heater.

Make it work, and it'll rock though.

I like how you put that thegoonden lol.
 
Multi-core CPUs do work though :confused:

They just work in an entirely different way to multi-GPU setups. New technologies like Hydra will hopefully make true multi-threaded rendering in 3D applications, just like CPUs do for supported applications now.
 
Dejavu i clearly remember this thread being done before.

You mean Nvidia surely.;)

Im no expert and these are just my thoughts, but im guessing that it will be down to how the two cores talk to each other and are made / allowed to interact with the drivers. If the two cores could have a bridging chip which interacts with the drivers then for all intents and purposes the two cores could interact with the outside environment (ie games etc) as one large group of shaders etc.
 
Multicore CPU's will "work" only when some sort of hardware layer is introduced to enable them to appear transparently as a single unit, because that seems a far easier problem to solve than basically "starting again" with programming.
 
I love it when people say "ah yea, will def not work, no way in hell is it gonna work" when we see both ATI/AMD and Intel head towards multi-core gpu's. Surely if two giants of the hardware world are both doing it (and Intel have said that theirs is going to be software controlled), it cant really be the "wrong" direction for hardware to go. We have seen games appear that are designed for multi-core use, we know its coming, we know hardware manufacturers as well as game designers want it, it was just a matter of time before it happened.

Would require some sort of hardware load balancing built-in to the die in that case, at least at the moment the software can dedicate tasks to whatever core is free as needed.
 
i think its going to be same thing 5850 , 5870, <-single core cpu

and 5870x2.

me waits for 5870 should be significant speed bumb from 8800gts g92
 
Besides the shared memory problem on multi GPU, both multi core CPU & GPU share the problems with getting things to scale.

The multi core CPU for most apps/games don't scale unless the apps/games have been made multi threaded. But you get the benefit of better multi tasking ether way.

The multi core GPU has a bigger problem that most games are not made for multi GPU & its the drivers & gfx hardware that makes it work most of the time, so intact multi GPU is already doing a better job at scaling software than multi CPU that was not programmed for multi scaling.
 
To be honest, I'm regularly questionning whether the 8.8 drivers were made for my 4870 as it stands now - they're awful. Trying to see something more complicated worked out on a driver level for the future makes me cringe.
 
Well most people were saying that it was impossible for crossfire/sli to scale 100%. You only have to look at cod 4 and all top range ati cards using crossfire do this so it is possible. They need to figure out how this was done and try repeat it in all games surely if 1 game can do it in the future all games should be able to.
