The i7-4900MQ is a top end 2013 Haswell Laptop CPU. It sports Intel's standard i7 configuration of four physical cores with support for eight hyper-threads. Comparing the 4990MQ and the flagship desktop i7-4770 shows that the performance gap between Desktop and Laptop CPUs no longer exists amongst top end Haswell based CPUs. Looking at the 4900MQ and the 3630QM Ivy Bridge Laptop CPU shows that the 4900MQ is around 30% faster, which is a big jump considering the relatively narrow age gap between the two. Overall the 4900MQ is a superb Laptop CPU that is able to give even the latest top of the range Desktop CPUs a run for their money. [Mar '14 CPUPro]

MORE DETAILS

The Core i7-3630QM has been included in the CPU group test as a reference Mobile CPU. This third generation Ivy Bridge processor has proven hugely successful and powers a significant proportion of today's high end laptops. Compared to desktop processors certain compromises have to be made and that is clear from the benchmarks. In terms of real world horsepower the i7-3630QM is comparable to first generation, and three years older, Core i7 Desktop processors. Where the Mobile processors excel is on energy efficiency and with a TDP of just 45 watts the 3630QM is the least power hungry processor in the group test. [Feb '12 CPUPro]
