We typically see the flagship K-series chips first whenever Intel launches a new family of desktop processors. These show the maximum potential for improvement in generational performance, such as IPC and core clock speeds, and show off the latest family to the best possible effect. Usually, a few months later, Intel launches their non-K-series SKUs, which have lower TDPs, with minor drops in core clock speeds, but offer the same level of core configurations for a usually lower price.
