Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS
The x264 video encoding though did benefit from HT.
The OpenMP-using GraphicsMagick wasn't benefited by Hyper Threading on this six-core CPU, but then again with this imaging application in particular we generally don't see it scale past a few cores anyways.
The 7-Zip compression benchmark saw a 30% performance boost thanks to Hyper Threading.
The Stockfish chess engine was also about 30% faster with HT enabled.
