The AMD CPU are 'factory set overclocked' base 4.7 GHz with upper level, user interface, of about 5.22 GHz. For rough comparisons, 3.8 GHz, the i7 CPU's draw about 172 watts with slightly higher overclocking the power TDP comparisons between the i7's and the FX9590 at about 4.6 - 4.7 GHz are not that much different. When the i7's are over clocked the watts rise dramatically. The FX9590 TDP is presented as 220 W 4.7 GHz where as the i7 4470K/4790K CPU is 84 W 3.4 GHz. We should also look at the overclocking TDP which is representative of the chip CPU set's characteristics. As such the TDP at the approximately same frequency, the cooling method, and skill sets of the user need accessing. The benchmark comparisons are noted with Intel's 4770K/4790K chip sets versus the AMD FX9590 CPU overclocking capability. The comparison is very biased by the author. The i7 4470 will have TDP of approximately 178 to 205 watts depending on the software load, motherboard type, and overclocking clocking frequency. Why author did not make comparison at the same overclocking frequency or several clocking frequencies to demonstrate the clear issue? From experience as the clocking frequency is higher the TDP increases significantly. Also note the the TDP is specified for the lower clocking frequency 3.5 GHz for the Intel i7 4470 CPU whereas the AMD FX9590 is documented with the much higher clocking frequency 4.7 GHz. The TDP is also dependent on the software load the more complex software the more the CPU has to work and hence the motherboard has to perform much higher TDP will result.

Why did the comparison only look at one type of motherboard for the Intel i7 4470? As the attachment illustrates the motherboard accessories interfaces, fans, pump, lights, LED's, drives, etc, have a considerable impact on the TDP rating.
