ATI's Multicard Solution Revealed?
by Alec Matias, May 06, 2005 1:26pm PDTHexus.net posted the first details on ATI's dual-card technology, dubbed Multi Video Processing units (MVP). The first card that will take advantage of MVP will be the PCIe Radeon X850 XT, which Hexus speculates will be shipping in the near future. The neat thing behind ATI's MVP tech is that you don't have to pair cards of the same model. As long as the two cards are MVP compatible, they'll work together. For instance, you buy the X850 XT in a couple months. Then two years later you buy ATI's latest and greatest, the "X1050 XT." Don't throw out the old card, just set it as the slave to the X1050 XT and you're good to go with MVP!
Nothing kinky here folks, the "Master/Slave" reference tells you which card is in control of assembling the final image in its frame buffer. Just like NVIDIA SLi, the ATi MVP solution will require a compatible mainboard (first seen by HEXUS on the ASUSTeK booth at this years CeBIT exhibition) and so it will be interesting to see which core-logic technology ATi will be supporting with its MVP. ... Having developed military solutions based on up to 32 cards in the past, it appears that ATi has decided on a "tile" based rendering approach as the default technology and perhaps the judgement was that this method offers the most ideal balance of speed and image quality (minimum size 32 pixels square). However it's more than likely that the ATi MVP solution will be flexible to offer other rendering modes like AFR (Alternate Frame Rendering) as well.Not only that, but another scenario given was if the motherboard had an on-board ATI graphics processor. Guess what, that also gets included into the mix! So it will be possible to have three VPUs running at the same time, powering our games.

I am already running a PCIe Radeon X850 XT? Does this mean all I need is a bois flash or driver update?

If it works well then I can see myself doing this.

Fanatic comment for this thread:
"ATi needs to get their current drivers up to snuff before they deside to tackle something this complex which will take a robust driver set"
Thanks!

nVidia technically had this roadmap in their drivers set for this with their 'unified architecture'.
It is taking it one step further that both companies will benefit off of.
It will be tricky to get to work I would think. After all, it would be diffacult to see whether the older (slave) gpu's/memory would actually speed it up, or hinder the performance lagging the (master) behind.
Sounds interesting.

In terms of fill rate, this is a good thing (on the surface), but there are a lot of question that come into mind for the REAL performance gain (sure, offload a specific frame or section to the other GPU, what's the overhead in getting that back). The SLI solutions are pretty "clean" b/c of the requirement of 2x nearly identical cards, but I really see potentially more issues with this ATIs solution than Nvidia.
Time will tell which is "adopted" better. GPU manufacturers are going to start putting "dual core" onto their systems (Nvidia has some out there already), this will yield the highest of gains in the coming years.

First I've heard of using multiple cards. Would your FPS be improved if you had 2 instead of the usual 1? Curious
