Hmm ? No, IOMMU is used for I/O virtualization.
That makes it so you can run VM's with much better speed/features.

For the memory bandwidth, that limitation is from the CPU/chipset design, and I think this will be much improved when quad channel memory support is available. Unknown if that will be made available for all chipsets AMD makes.
