Videocardz has leaked the Nvidia Official Reviewer's Guide Performance Charts. More numbers and charts at the link. In GeForce RTX reviewer's guide, NVIDIA is not using any other resolution than 4K. So all benchmarks (except VRMark Cyan Room) were performed at 3840x2160 resolution. In fact, the RTX 2080 series were 'designed for 4K', as the document claims. NVIDIA reference system includes: X299 Rampage VI Apex, Core i9-7900X 3.3 GHz, Corsair 16GB DDR4 (no frequency specified), Windows 10 (v1803), NVIDIA 411.38 drivers.
