With 80 cores I can get 40 2-core VMs all pegging their CPUs on a single processor without any core contention. Multiply up by the number of sockets. That might be the more interesting application for cloud providers than going for a single use case for the entire box. Where this might get interesting, depending on how the pricing stacks up, is that if you're in the cloud function business, this will increase the number of function instances you can afford to keep warmed up and ready to fire. In those situations you're not bottlenecked on the total bandwidth for the function itself (usually), your constraint is getting from zero to having the executable in VM it's going to run in, and from there getting it into the core past whatever it's contending with. If there's nothing to contend with and it's just waiting for a (probably fairly small) trigger signal, execution time from the point of view of whatever's downstream could easily be dominated by network transit times.
