EHM, WE NEED MULTI GPU SOLUTIONS.
However, multi gpu gotta evolve, i think this is what ati is going to do
lower end cards, in multi gpu. however, this card is locked to intel and amd chipset's (and uli ofcourse)
sucks abit.
But, people just, do we need multi cpu's ?, and the answer was yes.
Multi-cpu's was necessary because they are general purpose computing devices. You have to replicate all the features of the entire chip in order to boost performance.
GPUs are different. It is easy to add more power within a single GPU by adding more units of a particular kind--more ROPs, TMUs, and shaders. Adding more units by adding a second GPU is less efficient because of the need to duplicate redundant parts, because of the limited bandwidth for communication between them, and because of the computational overhead of combining the results. That is why new-generation GPUs with more units on a single die always outperform the multi-GPU configs of previous generations, and why multi-GPU configs scale so badly. Multi-GPU != Multi-CPU.
If CPUs were made up of lots of simple, specialized, scalable units like GPUs are, the same would hold true. Because they are not, the brute-force multi-core method is all that can be done. Maybe a future CPU architecture will change that, but it will probalby have to drop backward compatibility to pull it off.
