Synthetic benchmarks

Each row says whether a higher or a lower number is better (ranks and times are lower-is-better). Scores come from Digital Trends, esports.hwbot.org, 3DMark, HWBOT, ComputerBase, UL Benchmarks, TechSpot, Micro Center, Notebookcheck, PassMark, PCBench, Guru3D, Tom's Hardware and Vic B'Stard; 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.
