Lucid Hydra - Multiple GPU's with no need for SLI/Crossfire or Profiles

Will that prevent microstuttering? sounds good btw.

If they both operate on the same frame, then yes :) Microstutter would be a thing of the past.

But, as they say up norf... "you don't get owt for nowt". Having multiple GPUs operate on the same frame is generally not as efficient as having each GPU operate on a different frame. There is an additional overhead associated with the analysis of the frame and the distribution of the workload, and an associated increase in communication overheads. Given this, I'm expecting that it will scale less efficiently than existing crossfire or SLI methods.

That said, unless the difference is massive, in my eyes it will be well worth it. I've never been a fan of AFR.
 
MSI have a P55 board called "The Big Bang" that has a lucid chip on board, not sure on it's release though. I read that Intel have invested millions in Lucid, multi gpu Larrabee anyone?

Both those things were covered in the OP link; 30 days it said.


So would this finally enable you to use an ATI card and nvidia for physx without jumping through hoops? You'd only need drivers for the physx card so...

Very unlikely.

It's a driver compatability issue, rather than a hardware issue, with regards the physics processing problem. What this technology does is intercept GPU calls and distribute them.

The claims about being able to mix and match AMD and nvidia GPUs would still require some degree of co-operation between the two drivers, and this is something that I'm sure both ATI and nvidia would strongly oppose.
 
If you assign the nVidia card to be the primary GPU, PhysX should work. As I understand it its only disabled if the ATI card is used for display. We will find out in a month.
 
I have to say I'm looking forward to some hard figures for this, looks very promising. To be honest I'm surprised that Ati or Nvidia have tried this route.
But the cost of the chip alone may be a clear reason why none have tried before, I get the impression Intel is investing so heavy cause they want the IP for Laarabee which makes sense to me.
Fingers crossed for a 80-90% speed boost from the second card with no micro stuttering.
Always felt SLi and CF was a bit of a bad premium for the improvement they have for the second slot.

Fingers crossed this is going to work good :)
 
are they going to do it on MSI AMD based mobos , although I don't trust them from what happened last time I had MSI and AMD

29/10/2009 I guess we will know then.
But I wouldnt get to excited about it 20% performance increase methinks.

I think your figure is far to low, the investment for the project is so large and the chip cost so expensive I can't see this being less in performance than a CF or SLI. I would say it has to be better or they will never see a reasonable up take of such an expensive addition to a mobo. But that's just my thoughts on the subject.
