It's not complicated: The first bit, "Intel®", tells you that it's an Intel CPU (doh..). The second bit "Core™ i5-5200U" is the model number of the processor. The "U" stands for "Ultra-low power", meaning that it's a notebook / laptop processor. The third bit, "2.20GHz" is the speed of the processor, in this case, 2.2GHz, or 2 200 000 000 clock cycles per ...

I'd personally use cpuid, this converts a lot of the CPU flags into more meaningful information: sudo apt-get install cpuid cpuid

To check out a CPU I would recommend Wikipedia's lists of Intel processors. You can also check /proc/cpuinfo e.g. by using cat /proc/cpuinfo in a Terminal/Shell. One of the search results for "i5-5200U" on en.wikipedia.org is: https://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors So you can see it is a "Broadwell-U" (dual-core, 14 nm) and the ...

I just went through this exercise with thermald. First, I should point out that thermald was broken, even in fresh versions of 16.04, as it would not read its configuration file. This has now been fixed, so make sure that you have all of your updates installed. Also, the page you reference is pretty good, and also contains an example thermal-conf.xml ...

Depending on your processor, and for yours this is the case, cpuinfo_cur_freq and scaling_cur_freq are the same thing. For some processors, cpuinfo_cur_freq involves a hardware read and can be "expensive" in terms of time, which is the reason it requires sudo to access. Your CPU frequency can be outside the limits you have set, because the processor itself ...

As far as I have been able to determine 12 is the minimum pstate for your processor (or 1200000 KHz). You can check for yourself by reading the MSR_PLATFORM_INFO register and parsing the bits yourself. Here is an example for my processor, where my minimum pstate is 16: $ sudo modprobe msr $ sudo rdmsr --bitfield 47:40 -d -a 0xce 16 16 16 16 16 16 16 16 ...
