Intel is preparing to expand its Skull Canyon line of high-performance NUC compact desktops, with new models based on its upcoming "Coffee Lake-U" silicon. The company is preparing variants based on 28W TDP Core i3, Core i5, and Core i7 ultra-low power processors, and 300-series chipset. The Core i3 based parts offer 4-core/4-thread CPU configuration, while the Core i5 and Core i7 ones offer 4-core/8-thread configurations. One of these could even feature a large onboard graphics core cushioned by on-package eDRAM L4 cache. The three "Coffee Lake-U" based NUCs could be released in Q2-2018, which is quite a wait.
