Mobile CPU Speed Ratings

Mobile CPUs (central processing unit) are rated fastest to slowest (compared at same clock speed when possible). CPUs are also categorized as current, on the way out, or obsolete.

Note: For desktop CPU information please see our Desktop CPU Rundown.

Speed Conversion 1000 MHz = 1 GHz

Hint: If you are buying a new notebook, try to buy a notebook with a processor from the "current category" at the fastest speed you can afford. Those considering notebooks in the non-current categories should only buy heavily discounted models. Remember that notebook CPUs are mostly not upgradeable, so buy a notebook that is fast enough to meet your current and future processing requirements.
