Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS

The Assembly-written asmFish chess benchmark is another chess benchmark benefiting a lot from Hyper Threading.

GCC code compilation with multiple jobs also still benefits from the additional virtual cores provided by Hyper Threading.

Ray-tracing also has minor benefits from HT/SMT.

M-Queens also saw close to a 30% performance improvement with HT on this i7-8700K.

Long story short, Hyper Threading is still very much relevant in 2018 with current-generation Intel CPUs. In the threaded workloads that could scale past a few threads, HT/SMT on this Core i7 8700K processor yielded about a 30% performance improvement in many of these real-world test cases.
