There has been more than one leak suggesting that Intel is getting ready to launch an 8-core Coffee Lake processor, though the strongest evidence to date is a series of technical document listings on the company's website.

A user on Reddit discovered the listings, of which there are three that reference an unreleased "Coffee Lake S 8+2" part. Unless Intel suddenly changed its nomenclature, the 8+2 designation points to there being 8 CPU cores and 2 integrated GPU cores on this particular chip. For reference, CPUs like the Core i7-8700K are listed as being Coffee Lake S 6+2 parts, indicating 6 CPU cores and 2 integrated GPU cores.
