Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

"AMD Extends the UltraScale+ Product Portfolio"
If you just need a system to practice VHDL / Verilog on, the $50 entry point is a bit better. It won't be fast or big, but there's plenty to do and learn on something like that. The ICE40 is large enough to get a RISCV core for example.
