I have recently purchased a new laptop, and installed Ubuntu. It uses an AMD A8-4500M processor, which, according to the link below, should have a clock speed of 1900-2800 mhz.

When I use the "cat /proc/cpuinfo | grep name" command, it says the cpu speed is only 1400mhz. Could someone please explain why this is?
Thanks
