Is the 4 core limit really an issue? Really big deployments, where they are most sensitive to performance per watt, are finding it more cost effective to go with fewer cores per server because it gives a more optimal balance between processing power and memory bandwidth. Look at those google compute containers, each node has pretty modest specs. Lack of 64bit support is likely a bigger issue.
