GPUs get better performane only if the amount of data is large enought and it depents on whether you are using it on the gpu. Good to have a good sse implementation

It's quite easy to demonstrate improvement on a specific experiment, I'm looking forward for real use case test. Mat4 product and inverse are such great topics

nice gain!

I'd love to see a fleshed out article about this- perhaps adding a GPU implementation for comparison

Sorry, I guess the post was a bit unclear. I actually implemented all the SSE stuff in MSVC first. But I also wanted to make sure it works in Linux before I go to great lengths with this idea since I want to keep cross platform compatibility. I only needed a few minor changes to make it compile and run fine under GCC in Linux so it looks like I'll keep this code.

ah - scratch last comment. you never said you needed to install linux in order to experiment with intrinsics... I misread.

why do you think you needed linux for using sse intrinsics... ?
the Windows sdk comes with the xmmintrin.h header file which contains declarations for MMX/SSE/SSE2 intrinsics.

btw - i played around with gentoo years ago as well. It seems that most linux users I know spend an awful lot of their time configuring their system/desktops....

There is MinGW, which should have support for all SSE intrinsics you might need, so Linux as a SSE testground is a bit strange
