AMDs TDP does not Equal WATTS used but rather the average expected heat needed to be removed to maintain clocks. DOES that 1800X throttle during those tests when it hits that 129W? Like I have explained to you, when you can prove that a 95W cooler can not maintain clocks over normal desktop usage then you may have an argument. Till then statements like yours above are just ignorant rants of flustered posters grasping at straws.Values as 245W and 253W are total platform consumption, not the power consumed by the CPU alone. Thus official TDP ratings aren't being violated. Toms measured 250W on the CPU when overclocked it to 4.5GHz and with AVX512 offset disabled. Correcting for clocks we obtain for stock settings
250W (3.3/4.5)^2 = 134W
which agrees with the TDP. In fact, AT measured 149W for the same CPU on stock settings, and the 9W difference being easily explained by measurement errors (including loses from circuitry). However, the difference between 129W measured for the 1800X on x264 and the official 95W is not the result of small uncertainties in the measurement apparatus or small loses from 95% efficiency circuits. This 36% gap between measured TDP and marketing TDP is a result of the chip violating the marketing value.
