As a single chip computing cluster (multi cores on one chip) there a many advantages.
The Cores are asynchronous so this will average out the draw on the power supply.
Each core will have 4 to 6, 1+ Gigabit per second bi-directional serial interfaces to it's neighboring CPU cores.
Each Gbps serial will be addressable as a simple register read and write.
A patent is being filed for a cooling and power delivery system to allow for enormous clusters and ram on a very large chips. In theory it would be possible to build a single device running at 10 TeraFlops!
