I don't know about CUDA, however I've made an AVX2 based encoder a few months ago : https://github.com/phoboslab/qoi/pull/143 https://github.com/phoboslab/qoi/pull/143 I intend to create an AVX2 based decoder but I had absolutely no time to work on side projects in the past three months. You might also want to take a look at this streaming encoder if you want to encode large files with a tiny memory footprint : https://github.com/MKCG/php-qoi/blob/main/src/FFI/lib/qoi.c https://github.com/MKCG/php-qoi/blob/main/src/FFI/lib/qoi.c
