Turbo Boost -- what gives?
My new DELL desktop came with an Intel i7-2600 CPU @ 3.4 GHz w/ Turbo Boost technology. The specs indicate the CPU speed can go up to 3.8 GHz. I ran a few CPU speed tests and they were disappointing.
I monitor CPU core frequency with ArgusMonitor. When CPU load is at 100% on all 4 cores / 8 threads, I get an extra 0.1 GHz boost on each core (3.5 GHz instead of 3.8 GHz). That is by design, I think; I read somewhere that, if all cores are at top speed then Turbo Boost does not kick in. So I ran a test on one logical CPU. Still not getting 3.8 GHz -- maybe because the OS distributes CPU load over multiple CPUs even when the application only uses one core?
Is there a test that can demonstrate the full Tubo Boost capabability of a CPU? That is, one that results in ArgusMonitor showing at least one core/thread running at 3.8 GHz for a short amount of time? Thanks.
