Hyper Threading effect on benchmarks

I was thinking about what are the real advantages of having HT enabled on my Core i7 860. And got this numbers on Everest benchmarks.

It get 10ºC hotter with HT enabled, but I think that the extra heat come with good perfomance.

 

Yeah, today's HT is much improved over the original implementation.

My old dual Xeon 1.8Ghz with HT enabled was like having 2.5 CPUs overall.

 

I just got surprised by the results on FPU SinJulia (about 50% increase) and ZLib (about 30% increase.)

 

Benchmarks will show improvements as always, but as always, real world performance increaces won't be huge. The best use we at TPU have found for HT is running more WCG projects at once, heh

 

My own testing had similar results. Core i7 without HT enabled losses a lot of its performance potential.

 

what about single threaded performance i know alot of people used to disable HT on the P4's when doing single threaded benchmarks
