Why
is SMT good?
SMT implementations can be very efficient in terms of die size and power consumption, at least when compared with fully duplicating processor resources. With less than a 5% increase in die size, Intel claims that you can get a 30% performance boost by using
SMT for multithreaded workloads.

Leaving SMT enabled provided a 1% performance uplift on average across the 36 games tested. This means we see a 5% of better performance improvement in 8 games, with a 5% or larger performance drop in just 4 games.Jul 29, 2019

You say Hyper-Threading, I say Simultaneous MultiThreading\u2026
Essentially, nothing! Both terms describe the same technology, which doubles parts of the CPU core to help speed up multi-threaded tasks. Hyper-Threading is Intel's brand name for the technology, while simultaneous multi-threading is the more general term.Oct 13, 2017

Use the AMD SMT Option to enable or disable the AMD SMT functionality. NOTE: This option is available on servers with AMD processors. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Processor Options > AMD SMT Option.
