Hyperthreading quad core system
I recently purchased a system to last me through retirement, so although I'm a light user, I chose a fairly respectable i7 quad core with 16Gb RAM. Plenty of future-proofing there.
Process Explorer shows *eight* CPUs, so presumably the people who configured/supplied this system enabled hyperthreading (or it defaulted to ON). (Belarc Advisor confirms this)
In the past I've seen warnings that hyperthreading can reduce performance as it causes cache contention. The wisdom was "don't use it if you have sufficient CPU". Well, I've rarely seen more than about 5% CPU usage, so I seem to have an abundance.
What is the current consensus on hyperthreading?
