Not on 14nm lpp it wont.I'm not ignoring what Papermaster said, but people may be reading into what he said incorrectly.
Tock does not necessarily imply a new CPU core, and the roadmap that just leaked just showed it.
Process and circuit optimization is a totally and completely legitimate way to gain more performance. If 1800X could OC to 4.4GHz on all cores reliably, rather than the 4GHz-ish, then that'd be a solid improvement, no?
It will a HP process for that, samsungs 14nm lpu would do the trick, BUT i cant see AMD doing that for a meagre upgrade, expensive so i think some low hanginging fruit will be fixed, netting 5-10% ipc, not sure if they would make the jump to 14nm lpu, be great if they could.
