according to that site : http://www.cpu-world.com/CPUs/Puma/AMD-G-Series%20GX-412TC.html
the AMD GX-412TC is supposed to run @1200Mhz while it is @1000Mhz on the APU2. is it underclocked ?? if yes then how to clock it @1200Mhz ??
Yes, in theory the CPU should be able to boost speed when not all cores are loaded.
In practice we have not been able to achieve this. No meaningful help from AMD, I'm afraid.
For server use it may be useful to use cpufreq to lock the CPU speed to 1 GHz, rather than having the sluggish reaction to load spikes. The power penalty should not be that big.
there is no Boost frequency in that model, see the comparison here at the bottom : http://www.cpu-world.com/CPUs/Puma/AMD-G-Series%20GX-412HC.html#cmp_cpus
it is normaly fixed to 1200Mhz, the version with Boost Frequency (up to 1600Mhz) is : GX-412HC and not TC
This CPU must run at 1200Mhz unless it is underclocked somewhere in the bios...we can get 20% more out of it, which is not negligible, there must be a mistake somewhere...
I would put more trust in this table:
Which says 1GHz / 1.4 GHz boost.
well, i found on the AMD website a document saying :
GX-412TC - GE412TIYJ44JB - 1.0GHz/1.4GHz
Now it has a Turbo frequency to 1.4Ghz ?
see here : https://www.amd.com/Documents/AMDGSeriesSOCProductBrief.pdf
But it is sold as a 1200Mhz soc : https://www.avnet.com/shop/us/p/processor/processors/amd/ge412tiyj44jb-3074457345628703583
