You have to be careful when doing that though. For example Desktop i5 CPUs are almost all quad cores. Laptop i5s are all dual cores with hyperthreading. All desktop i7 CPUs are either 4 or 6 core CPUs with hyperthreading. Some laptop i7s are dual core with hyperthreading, and some are quad core with hyeprthreading. Laptop CPUs are always clocked lower than their desktop counterparts to reduce power consumption and heat. You have to keep these factors in mind.
