The specsheet of a Lenovo IdeaPad S530-13IWL has allowed us to know the existence of the new Intel 9000 series mobile CPUs. These are the Core i7-9550U, i5-9250U and i3-9130U. The laptop datasheet, spotted on Twitter by @momomo_us
, confirms new members of that family , with "IWL" at the end of the model name meaning "Intel Whiskey Lake", a family launched last October with the Core i7-8565U, Core i5-8265U and Core i3-8145U. There is no confirmation from Intel on this rumor, and there aren't much details about the CPUs either: clock speeds and core counts are not specified, though should remain quite similar to the previous members of the 8000 series.
This information points to a light rebadge of Whiskey Lake CPUs according to NotebookCheck given that there is no mention of the 9th generation of processors. This is weird because the 8000 series is basically a synonym of the 8th Gen and the same happens with the 9000 series and the 9th generation. It seems the Core i7 will be a quad-core CPU with Hyper Threading support and 8 MB of L3 cache, while the Core i5, with the same core count, will have 6 MB of L3 cache. The Core i3 CPU would be a dual-core chip with 4 MB of L3 cache. We'll have to wait for an official confirmation to confirm the specs and advantages over the older models.
