According to CPCHardware, the Intel Core i5 8400 will feature 6 CPU cores and 9MB of L3 Cache, won't support Hyper Threading, will be clocked at 2.8Ghz, and its TDP will not be exceeding (theoretically) 65W. On the other hand, the Intel Core i5 8600K will also feature 6 CPU cores and 9MB of L3 Cache, won't support Hyper-Threading, will be clocked at 3.6Ghz and its TDP will be at 95W. Regarding the Core i7 CPUs, CPCHardware revealed two models: Intel Core i7 8700K and Intel Core i7 8700. The only difference between them is that the non-K version will be clocked at a lower frequency (Core i7 8700K is reported to be clocked at 3.6Ghz whereas the non-K version will be clocked at 3.2Ghz). Apart from that, they feature the exact same features. Both of them come with 6 CPU cores and 12MB of L3 Cache, support Hyper-Threading, and offer a TDP of 95W. What's also interesting here is that according to CPCHardware, this CPUs will be compatible with the LGA 1151 socket, meaning that those already owning these mainstream motherboards will be able to upgrade to the newest CPUs without any issues.
