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.

Zen 5's Leaked Slides
I don't know how often it's a problem, but I work for a company doing software video encoding, and we always fill up all the dimm slots on servers to have as much bandwidth as possible, even if we have only really use maybe 1/4 of the RAM.
I'm not sure any of the standard Linux tools can show you memory bandwidth usage easily (maybe perf), I know we use Intel PCM (https://github.com/intel/pcm) and AMDuProfPCM (https://www.amd.com/en/developer/uprof.html)

CoreFreq, a CPU monitoring software frequencies, ratios, C-states
The Intel PCM suite does what you seem to be describing w/o a kernel module, and it uses nicely abstracted MSR accesses so that its portable to any OS.

Will you actually be able to utilize the connectivity offered with high-end AM5 boards?
For my purpose, I want 1. Enough, but not excessive lanes for GPU. For upcoming PCIe5 enabled GPUs (which may not even happen just yet), we don't know if they can saturate 16x. Would be nice if someone could run https://github.com/intel/pcm pcm-iio and measure. If it turns out that PCIe5 enabled GPUs aren't using more than 8x bandwidth, then X670E 8/8/4 mode makes sense, if you can saturate the remaining lanes with something else.
