Synthetic benchmarks

Each row says whether a higher or a lower number is better (ranks and times are lower-is-better). Scores come from The FPS Review, Notebookcheck, GadgetVersus, Electronic Clinic, Silent PC Review, PC Guide, Geekbench Browser, NanoReview, PassMark, Tom's Hardware and numberworld.org; 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.
