Intel is hours away from launching its new Core i7-8000 series of processors, with the new Coffee Lake CPU architecture being led by the flagship Core i7-8700K, which has now been officially delidded.
Intel's new Core i7-8700K was delidded by HKEPC, wherer we see that the new Coffee Lake-S processor has a die size of roughly 151mm2, making it longer than the die of the 7700K. This means that for the additional 2 CPU cores on the Core i7-8700K, Intel is using around 29mm2 more die area.
We should expect nearly all Core i7-8700K processors to reach 5GHz with some good cooling, think AIO coolers. If you want to go higher than 5GHz, you're going to want to delid the 8700K, to which we should expect delidding tutorial videos on YouTube any day now.
