48 desktop and 66 mobile processors tested in Cinebench 11.5

In late-May, we published a huge round-up of 45 desktop processors (opens in new tab), followed by a review of Intel's fourth generation Core processors (opens in new tab). 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 - 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 as 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.

A number of things stand out looking at the results. The fastest mobile processor that we've tested, the Core i7 3920XM quad-core from the Ivy Bridge generation, scores 7.2 points, slightly less than the desktop Core i7 3770. The most high-end Haswell mobile processor, the Core i7 4930MX, which we haven't tested yet, will likely be slightly faster. The Core i7 4700MQ 'standard' mobile Haswell quad-core CPU scores 6.9 points, roughly on the level of the desktop Core i7 2600K.
