Intel created the Core i9 brand to differentiate two key groups of Core X series HEDT (high-end desktop) processors, with the Core i7 X-series parts featuring 28-lane or 16-lane PCIe interfaces, while the Core i9 X-series parts featuring the full 44-lane interfaces present on the “Skylake-X” silicon. The Core i9 brand also earned a degree of exclusivity as it allows Intel to ask upwards of $999 for these client-segment parts, with the top-end i9-7980XE scraping the $2,000-mark. Intel sees the potential for a similar segmentation for its mobile processor lineup, even if not on grounds of PCIe lane budget or core-counts.
The Core i9 mobile processor family could bring the highest-levels of 6-core “Coffee Lake” desktop processor performance to the notebook platform. Intel is giving final touches to the Core i9-8000 series “Coffee Lake-H” processor lineup, which could feature the full 6-core/12-thread configuration of the “Coffee Lake” silicon, alongside 12 MB L3 cache. The first SKU in the lineup could be the Core i9-8950HK, sniffed out from the change-log of the latest FinalWire AIDA64. These chips could enable large (>17-inch) gaming notebooks with one or more high-end graphics cards, the latest advancements in cooling, 4K UHD or curved displays, etc.
