There is nothing here that will trickle down to the enthusiast market. The fabric does not creat multi-cpu systems, it allows you to connect multiple servers together. It sits below the chipset, not between the CPUs.
Take a look at the back of the rack and see all of the cabling and redundancy, taking up space and consuming power. That is what this system solves. It doesn't let you combine 64 systems into a single supercomputer, it helps you better manage the deployment of 64 individual servers.
Perhaps you can still dream, but you are dreaming about a capability that does not exist.

Yup, this fabric is only useful for the enterprise..... especially workloads that are relatively atomic and heavily threaded..

Because you are not looking at the whole picture but selectively choosing a point.

PCIe latency is in the 200-1100ns range. HT latency is in the 150-600ns range. This is a big deal.
