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.

Blaze: A High Performance C++ Math library
Is Eigen still alive? There's been no release in 3 years, and no news about it: https://gitlab.com/libeigen/eigen/-/issues/2699
- Gentoo -Os vs -O3 application startup time?

The Case of the Missing SIMD Code
I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?
I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

FetchContent and PROJECT_IS_TOP_LEVEL
I am trying to include Eigen in my project via FetchContent. They define/assume-defined PROJECT_IS_TOP_LEVEL on line 19 and, among other locations, on line 607 in their top level list file.

Common practices when doing image processing on the GPU
Eigen is a header-only library, thus simply cloning it from the official repository into the FOGGDD folder should be enough.
- Use TFlite in a Cmake Project

I've decided to learn Godot and it feels like I have "lost"
math library because you should never implement a math library yourself, and you probably want somethign more focused on performance than STL. GLM may work if you just need basic vector support. Eigen may help for a more physics heavy game. But I'd probably find something in-between those two

Emulating AMD Approximate Arithmetic Instructions on Intel
Yikes.
A lot of code uses _mm_rsqrt_ps (sometimes) followed by a Newton-raphson update to compute a "precise" 1/sqrt(x). Here's a good example of NEON's rsqrt being sufficiently different from Intel, that more iterations were necessary for Embree on ARM [1].
Because I only cared about vectorization a long time ago, and AMD was so uncompetitive then, I'd bet a lot of code assumes that the SSE rsqrtps values match.
