benchmark hyperthreading cpu on/off

Post by Tony »

Hi,

Is there a real benefit to investing in a hyperthreading processor rather than in a processor without hyperthreading in relation to the use that can make of it Twincompile ?
Does anyone have a compilation benchmark with Twincompile comparing enabling and disabling hyperthread at CPU level?

Someone else may be able to give you some actual benchmarks for this - I don't happen to have any because I've always used the hyper-threading processors.

In general, the hyper-threading processors are always faster than the non-HT processors because they're the higher spec editions of the processors. This goes for Intel as well as AMD. C++ compiling is also mostly integer operations, so it's able to take advantage of the dual math operation support that hyper-threading supports.
