Intel is obviously cllose to the release of the an 8-core/16-thread processor on its mainstream platform, since entries in the SiSoftware benchmark database already reveal a 2.6GHz processor with 16MB L3 cache.
Intel's weapon in its fight to beat AMD's Ryzen processors seems to have a large 16MB cache, considering that the already released Core i7-8700K has 12MB, but it is listed to have a lower than expected clock speed.
The results you see were measured on an unknown Kaby Lake client system, we can assume that the new processor is compatible with existing Z370 motherboards.
WIth the new 8-core CPU, Intel obviously aims at AMD's 8-core Ryzen CPUs, which have stolen a lead in multi-threaded benchmarks against Intel's similarly-priced 14nm Core i7-8700K. But don't forget that Intel is also offering the high-end desktop X299 platform, with 8-core CPUs available there.
It remains to be seen how AMD will plug the performance gap between its 8-core Ryzen CPUs and its current mainstream flagship, the Core i7-8700K.
