Coffee Lake is another architecture made on the 14nm process, some rumors claim we'll see these chips in September. The Coffee Lake chips will stick with LGA1151 and are a further development of the Skylake architecture. Probably the biggest change here is that Intel is bringing 6-core processors to its mainstream segment.
Here's a look at the specifications of Coffee Lake engineering samples that are circulating right now:
Core i7 8700K: This is the high-end model, it reportedly has a 3.7GHz base frequency. It has six cores, twelve threads and a TD P of 95W. There will also be a Core i7 8700 non-K model with a 3.2GHz base clock.
Six-cores in the Core i5 series? If the rumors are right, we'll see six-core processors in the Core i5 series but these versions will lack Hyper-Threading. CanardPC talks about a six-core Core i5 8600K with a 3.6GHz base clock and 95W TDP, as well as a six-core Core i5 8400 with 2.8GHz clockspeed and 65W TDP.
Six-core for the mobile market. The laptop market is expected to see the first pure mobile six-core parts. These versions are expected to have a 45W TDP and will run at lower clockspeeds of around 2.0GHz. Quad-core versions of Coffee Lake mobile are expected to hit a TDP as low as 28W, placing them in Intel's low-power U-series for the first time.
