The overclock was achieved on the ASRock Z370 Professional Gaming i7 motherboard in combination with watercooling. The Core i7-9700K has eight cores but lacks Hyper-Threading. Interestingly, this chip and the Core i9-9900K mark the return to soldered heatspreaders, which should result in better thermals and easier overclocking.
There are some Cinebench scores too:
In Cinebench R15 the new CPU reached 1827 and 250 points in multi- and single-threaded tests respectively. This puts it in Ryzen 7 2700X territory, and 200 points above Core i7-8700K, which this SKU is replacing. The single-thread performance is without a doubt a great achievement here (check the OC3D review for reference). Or was it the fact that no Z390 motherboard was required to achieve this score?
