OCAholic came across the specifications of four six-core Coffee Lake processors from Intel. This includes two 12-threaded models and another two models without Hyper-Threading.
If the leak is accurate, these chips could be pretty potent. They're compatible with the current LGA1151 socket but at the moment it's not clear whether a new motherboard will be required.
These are the first six-cores in Intel's mainstream processor lineup, the most powerful model is the Core i7-8700K. This six-core, twelve-threaded 95W TDP chip features a 3.7GHz base frequency and hits a Turbo Boost frequency of up to 4.7GHz on a single core.
The specifications of the other chips are listed below.
