As the topic suggests, what CPU would give me the best odds reaching a stable 5+ GHz overclock on all cores? The CPUs I'm considering are: 8086K 9700K 9900K The 8086K is a good contender I guess since it's a "factory binned" 8700K out of the box. The 9700K is not as power hungry as the 9900K and thus would produce less heat meaning better chances to reach a stable and high overclock without the temps going through the roof. The 9900K is more power hungry vs both the 9700K and the 8086K but since I won't need the HT meaning I can disable it, maybe that would increase my chances reaching a high and stable overclock while at the same time keeping the temps healthy. I'm also wondering if the 9900K in fact might be a 9700K binned by Intel to make sure it will be able to reach its listed clocks with HT added and then get the 9900K label rather than the 9700K label? However, since it also comes with more cache I guess they indeed are two completely different CPUs? As for motherboards, I'm an MSI guy and have been looking at the MEG Z390 Ace or the MPG Z390 Gaming Pro Carbon. Not sure if the latter would do the job just fine or if the Ace would increase my odds reaching a stable 5+ GHz overclock? Many thanks for any tips and input!
