Late May we published a huge round-up of 45 desktop processors, followed by a review of Intel's fourth generation Core processors. Our readers immediately, and understandably, came with the request for a similar group test of laptop processors. It's a great idea, but difficult to conduct because laptop processors often aren't available separately like desktop CPUs are. That means it's difficult to measure the performance of only the processor, as many other variables are present such as the amount and speed of the RAM, the power management of the processor, the type of hard disk or SSD, and so on.
Hardware.Info tests about 250 laptops and tablets per year, and there is one benchmark we use on all Windows products that almost only measures the power of the processor: Cinebench 11.5. The benchmark does test professional 3D rendering which isn't exactly the main purpose of laptops, but Cinebench has consistently proven to be a very good indicator of the power of a processor with multi-threaded workloads. Others in the industry also use Cinebench has a measure of overall processor performance.
So we used Cinebench 11.5 to test 66 popular mobile CPUs, and we compared their scores to those of 48 desktop processors tested with the same benchmarks. The results you will on the next page.
Cinebench 11.5 is an excellent CPU benchmark that's affected very little by other system components.
