Now the schedule for bringing the older models of Intel Skylake-X processors to the market is no longer a secret: next week it will be possible to buy processors with up to ten units, in August there will be a model with 12 cores, and more "large" processors with the number of cores up to 18 pieces will have to wait until October.
According to the source, traditionally Intel uses three types of crystals for the release of its server processors: with a small number of cores (LCC), an average number of cores (MCC) and a large number of cores (HCC). To make the whole range of desktop processors Skylake-X it was decided to use two versions of the crystal: LCC will give life to models with the number of cores to 12 pieces inclusive, and variants with 14-18 cores will use the MCC crystal. Its heat dissipation needs to be adapted to the specifications of LGA 2066, so it takes some time to prepare the announcement of older Skylake-X models.
Resource Bits & Chips concurrently reports that Intel may even need a new revision of the LGA 2066 connector, which withstands a higher TDP to accept without complications the Skylake-X processors with more than 14 cores. In this case, you will have to change motherboards in order to move from a "low-core" processor to a "multi-core" processor.
