Do you mean cores or physical CPUs? Also do you mean temperatures or clock speeds? If you mean cores and temps, only slightly, most likely by 1 or 2 degrees C. If you mean cores and speeds, again only slightly, most likely by .1 or .2 GHz. If you mean physical CPUs, temps could vary a lot based on cooling solutions between the two and whether they are the same. As for clock speed with physical CPUs, it could vary a lot again based on how much voltage is applied to the separate CPUs.
