Per-thread spread
Every cached community rig for this chip, bucketed by hashrate per mining thread.
Lane speed vs lane volume
Every cached rig as one dot: DIMM speed on x, per-thread hashrate on y, colored by populated memory channels per socket. Same silicon, different memory configs — the spread is the memory tax (or dividend).
