The article somtimes says 100x, other times it says 100% speed boost. E.g. it says "boosts the app’s ‘rangedetect8_avx512’ performance by 100.73%." but the screenshot shows 100.73x.
100x would be a 9900% speed boost, while a 100% speed boost would mean it's 2x as fast.
Which one is it?
- pizlonator 1y agoThe ffmpeg folks are claiming 100x not 100%. Article probably has a typo
- k_roy 1y agoThat would be quite the percentage difference with 100x
- MadnessASAP 1y ago100x to the single function 100% (2x) to the whole filter
- torginus 1y agoI'd guess the function operates of 8 bit values judging from the name. If the previous implementation was scalar, a double-pumped AVX512 implementation can process 128 elements at a time, making the 100x speedup plausible.

- ethan_smith 1y agoIt's definitely 100x (or 100.73x) as shown in the screenshot, which represents a 9973% speedup - the article text incorrectly uses percentage notation in some places.
- andersmurphy 1y agoThe article probably contains traces of blue.
