all the CPU are tacted by roughly 1000 Mhz which is clearly not the max value (Intel page [1] says 4800 / 3500 MHz).

why do you expect to see something more?

what shows your /sys - this is what you also see in the UI

$ cat /sys/devices/system/cpu/cpu*/cpufreq/*freq 3400000 1600000 2061434 3400000 1600000 3400000 1600000 1896795 3400000 1600000 3400000 1600000 2181524 3400000 1600000 3400000 1600000 2186013 3400000 1600000

You can usually limit the power or it is done by the policy and scheme you are using. If you use in kernel user space, it will give the OS the opportunity to control the policy by some software. There are also tools to set the policy in command line
