Synthetic benchmarks

Each row says whether a higher or a lower number is better (ranks and times are lower-is-better). Scores come from 3DMark, Notebookcheck, Forbes / Tirias Research, UL Solutions, CpuTronic, TopCPU.net, PassMark and AskGeek.io; 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.
