Vector math library benchmarks (C++)

• vectormathbench

  3 8 7.3 C++

  A collection of microbenchmarks for various game- and graphics-centric vectormath libraries.

  

Hey all, I recently posted this question on this subreddit and decided to do some benchmarks between GLM, DirectXMath, and SimpleMath from DirectXTK (thanks for the recommendation - hadn't heard of this one before!). I pulled the benchmarks out of my engine and moved them into a dedicated repository, which includes the most recent benchmark results Based on my last thread, I was a bit surprised to see GLM generally beating out DirectXMath. I haven't inspected the generated assembly, but my assumption is that GCC and MSVC's (I was testing on my Linux laptop + my Windows workstation, both of which showed similar results) auto vectorization simply beats out the manual intrinsics of DXM. Please don't hesitate to correct me if my interpretation is incorrect!

  2 250 2.3 C++

  Modified version of Sony's open sourced vector and matrix math library. (by glampert)

I actually used that library rather than GLM back in college (specifically this fork) and thought about including it, but it doesn't look like it's been maintained in a long time and seemingly has poor cross platform support (incl for different processor architectures).
