***News*** Linear performance scaling on multigpu systems!!!

I don't know if this has been posted before, but it's certainly very news worthy:

In summary: This Hyrda chip intercepts DirectX and OpenGL calls to the GPU driver, determines which GPU's render what, then sends the balanced workloads to the GPU driver. The GPUs then render the image, then send it back to the Hydra chip for display. All the while achieving linear scaling (they demo'd Crysis at 60 FPS with two 9800 GT's). You can't mix and match different branded cards (ie HD4870 + GTX 280 is a no no), as the OS only accepts one display driver.

That's my very simple, broad summary. I recommend that everyone reads it for themselves, as this certainly sounds like the 'Holy Grail' of multi-GPU systems. Performance scales linearly from 1, 2, 3 and even 4 GPU's!

And so it would be possible that 2 HD4870x2 or 4 4870 in CF/ Tri GTX280 SLI to give 4x times HD4870 performance / 3x timesGTX280 performance respectively. :shock:

This is what SLI and Xfire should've had to begin with. It will no longer be a waste to buy 2 or 3 cards with each one being fully utilized 100% instead of 30-50% like we see now. Makes you wonder why nvidia or ati couldn't come up with this......

Jesus, this means I wouldn't have to upgrade my 2 8800GT's! So when's this coming out?holmes88777

first half of 2009 according to techreport:D

Holy hell, Crysis at 60FPS with two 9800GTs. There will be no need for Tri-SLi then. Elann2008

...and that's why Nvidia and ATI don't want you to know about it.

Why spend $500 on a brand new GPU, when you can get 2 $120 GPU's instead?

Sneaky sneaky..

I cant wait for this thing to release.

Now 4 4870x2 (8 rv770) could give insane powa!

R700 supports 4 way crossfirex!

This chip will be included in motherboards based on intel right?and intel doesn't support sli, this means that nvidia users won't be able to make use of it until nvidia allows (or sells) sli technology to intel,which they won't because this will put an end to their mobos as people are only buying it for it's exclusive sli.Games_pro

It also be cool if it was a addon card for pci or pci_e 1x slot which is like a phyics card type of thing and it assisted sli.04dcarraher

From what I've read, all information passes through this chip before going to the CPU or GPU. I don't think you want to bottleneck that with PCI or PCIe. It'd be nice, but I don't see it happening. I hope the boards with this chip aren't too expensive.

Hopefully!
