The Core i5-8265U is a quad-core processor with eight threads, it has a base clock of 1.6GHz and a 3.9GHz Turbo. Presumably, it has a 15W TDP and an integrated graphics solution comparable to the UHD 630.
Next there's the i7-8565U, another quad-core part with eight threads. The 3DMark listing shows a base clock of 1.8GHz. The Turbo is listed at 4.6GHz, but that seems inaccurate.
Whiskey Lake is aimed at laptops and is the successor to Coffee Lake-U. Furthermore, Intel will also be launching Amber Lake-Y, a 4.5W TDP series also fabbed on 14nm+++.
