TDP stands for thermal design power or, depending who you ask, thermal design profile. The TDP number tells you the maximum heat a CPU can uses in watts. More watts equals better CPU performance, but also higher temperatures and more power consumption. PC OEMs can sometimes lower the TDP on a chip to increase battery life on a laptop or raise it up to boost speed
Check out your CPU’s TDP to determine what kind of CPU cooler you need and to make sure you have a PSU (power supply unit) that provides enough juice.
