Intel seems to be preparing a refresh of its existing Tiger Lake-U and Tiger Lake-H CPUs with faster quad-core models. The lineup will be pitted against AMD's Ryzen 5000U and Ryzen 5000H Cezanne CPUs that are available in several configurations.

Four models have leaked out by several retailers & OEMs. The models include two Tiger Lake-U & two Tiger Lake-H CPUs. Now you may be wondering that why is Intel offering a refresh for its yet-to-be-released Tiger Lake-H SKUs already but the refreshed lineup is mainly for the H35 variants that feature quad cores while the H45 variants launch in mid of 2021. Both lineups are based on the same Willow Cove cores and feature quad-core-only configurations.
