ThreadRacer is a CPU benchmark utility that is able to put a normal priority CPU bound thread(s) on specific processors and/or run a single CPU bound thread on multiple processors. It is the ultimate multi-core benchmark setup, particularly when testing the true performance of logical cores.

‘CPU’ vs. ‘Core’

These two words are synonyms, though in this world of rapidly evolving technology they have changed a bit. CPU is now used to represent a single physical unit, where-as core is used to represent one of many CPUs on a single die. In this way, it can be confusing. Just remember, 4 cores really means 4 CPUs all on one chip.

Reminder about what CPU % use is

I want to remind people that CPU utilization occurs in micro-bursts, and the % use per second is not a perfect representation of how fast or slow a CPU is. That is to say, just because that metric shows only 75% of a CPU consumed, that doesn’t mean that you had an ‘extra’ 25% laying around. The speed at which that 75% was executed matters too. At best this metric gives you some idea of how CPU intensive your operations are.
