Ubuntu – Any way to check the clock speed of the processor

cpu

Is there any way to check at which clock speed my processor is running?

I have already tried cat /proc/cpuinfo but the clock speed I'm running isn't showing. I know Ubuntu 12.04 (Precise Pangolin) requires 700 MHz and VGA, but will an AMD Mobile Sempron work?

From the command line type lscpu. The information will be at CPU MHz:

~$ lscpu | grep MHz
CPU MHz:               804.901
CPU max MHz:           3200.0000
CPU min MHz:           800.0000

This is not „the terminal way”, but you can look the processors up on cpubenchmark.net. It will give you an approximate value how well their benchmark performs on the selected processors. There is a page on how they test.

AMD Turion 64 X2 Mobile TL-60: 994 points
Intel Core2 Duo T5500 @ 1.66GHz: 925 points

According to the readings, they have roughly the same power and both play in the „Low Mid Range CPUs League”.

Ubuntu – Ubuntu get actual current CPU clock speed

To know all your CPU Specs use the command:

lscpu

To get the specific frequency of your CPU use the command with a grep like so:

lscpu | grep MHz

It will give you output like:

CPU MHz:               2723.789

To see realtime CPU speeds fluctuation use :

watch -n1 "lscpu | grep MHz | awk '{print $1}'";
