A few weeks ago the French hardware magazine Canard PC Hardware has published information that the upcoming AMD Ryzen CPUs should allow overclocking to 5 GHz with an ordinary tower cooler.
According to an experienced overclocker from PCGHX this information might be not right or at least incomplete. In other words the new AMD Ryzen chip could hit 5 GHz with just one core and the overclocking headroom with all cores activated could be somewhere above 4 GHz.

Apparently all of this is pure speculation and so far there are no reports available, where the overclocking headroom of AMD’s Ryzen CPUs has been tested.

During the past years we have learnt that all the "large" CPUs with more than four cores struggle in achieving very high clock speeds. Looking at Intel’s Broadwell-E CPUs for example we see that it’s hard to drive them well past 4.0 GHz with all cores and Hyperthreading enabled and under full load.

Since the upcoming flagship CPUs from AMD are also going to feature eight cores it could actually be a surprise if they would be capable of hitting clock speeds in the region of 5 GHz having all cores activated. It would all be even more surprising if that was possible with only a tower air cooler.

If all the past rumors are correct, the upcoming AMD Ryzen should be pretty competitive and as fast as an Intel Core i7-6900K which features eight cores running at 3.2 / 3.7 GHz.
