Synthetic benchmarks

Each row says whether a higher or a lower number is better (ranks and times are lower-is-better). Scores come from Notebookcheck, Tom's Hardware, CGDirector, technical.city, Puget Systems, GadgetVersus, NanoReview, HardwareDB, Geekbench Browser, PassMark and HWBOT; each row links its sources, and where they differ the cell shows their median. Empty cells mean we don't yet have that benchmark on file for the SKU.
