Synthetic benchmarks
Each row says whether a higher or a lower number is better (ranks and times are lower-is-better). Scores come from Tom's Hardware, CGDirector, Hardwareluxx, Notebookcheck, TechPowerUp, PassMark, CpuTronic, Geekbench Browser 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.
