The 5GHz OC number has become public:
Quote:
...Ryzen sample single-core overclock is 5GHz on air, primary bottleneck for all-core OC was low-quality VRMs on the motherboard
..Ryzen overclocks out of the box and if the single core OC is any indicator, the primary hurdle enthusiasts will have to overcome will be one of the quality of motherboard and of course, electromigration.
.. [speculate] you can realistically expect cherry chips to overclock up to 3.8-4.0 GHz on all cores with a high-end cooler and a mature enough revision of the Ryzen processor...
Electromigration becomes a bigger issue as architecture shrinks (Ryzen is 14nm), I speculate. This causes premature aging. However, its a trade off -- that fanatics may be willing to accept
