The AMD Opteron 6200-series processors feature four to sixteen cores per CPU, and can be used in two- or four-way configurations. Each pair of cores is actually two integer processing units with a shared floating point unit, but this focus on integer performance allows substantial increases in the processing capability of the whole computer under most workloads. The sheer number of cores available on this platform make it great for servers and high-performance computing, especially with software that is built to run in parallel. These configurations are also ideal if massive amounts of RAM are needed.

Using a four CPU setup with these processors will give you up to 64 cores to work with, but the massive motherboard needed limits case selection. A two CPU motherboard is much more manageable in size, giving additional chassis options, and provides up to 32 cores.
