rMB - 1.1GHz not seeing Turbo above 2.0GHz

[Ynk]

I have been testing out the rMB this week - Base model 1.1GHz - This is listed as being able to Turbo to 2.4GHz.

I've been monitoring clock speeds using Intel Power Gadget (https://software.intel.com/en-us/articles/intel-power-gadget-20)

I have not seen under any workload single core or multi core, the CPU burst above 2.0GHz even for a second.... Even with the temps down in the 30-40C range I never see anything above 2.0GHz.

Just wondering what others are seeing - I would be interested to know what turbo speeds you're seeing even if you don't own the base model as if you can see it reaching over 2GHz I might consider switching it over for an upgraded CPU model.

I don't have a rMB, but when using Intel Power Gadget with a quad-core Sandy Bridge i7-2635QM, which has base frequency of 2.0GHz and turbo of 2.9GHz, I have *never* seen it above 2.6GHz, and mostly 2.0-2.4GHz.

I do wonder under what conditions the full turbo speed is possible. Maybe only when a single core is active and every other core is basically shut down?

Maximum turbo boost specification is for single Core, full load on multi Core`s the maximum frequency is lower; I see 3.1Ghz on my 2.6 Quad Core 15" & 3.1 on my 2.8Ghz 13" Retina while using Handbrake to see the absolute maximum of 3.3Ghz.

Core M is all about efficiency, so pushing the CPU to max boost may need, a different approach, have you tried command line tool called “yes” this will load up single and multiple Cores or you can try Prime 95 for OS X if you want to stress/torture test the CPU

Yes http://osxdaily.com/2012/10/02/stress-test-mac-cpu/

Remember you also have to consider thermal management, as it will cut in to protect the CPU

same here

can't be explained unless you see IA and GT as additive even then they add up to 2.3GHz mostly instead of 2.4GHz

it seems Apple throttled the max turbo although they allow 6.7W of power consumption for a long time = excellent thermal management
