TDP is the maximum thermal power in watts that gets generated as waste heat that needs to be removed. A processor can consume 50 watts, but produce 100 watt waste heat, another processor can consume 400 watts and produce 100 watts of heat. Both have 100w TDP, but one consumes 150w, the other 500w. This is why TDP doesn’t tell the full picture.
Because Ryzen 2 is manufactured on 7nm, it’s extremely efficient in that it doesn’t convert its energy into waste heat. Both 3900X and 3950X are designed to produce no more than 100 watts of heat. But of course, that doesn’t say how much current they actually draw under full load. That specification is the key and is very hard to find.
When these chips are released, you will likely see reviews that measure the total system power, that is the power CPU draws plus PSU inefficiencies, VRM inefficiencies, motherboard component inefficiencies, on top of all the power ram, ssds, and everything else uses. So it will not be an accurate measurement, but it will give you an overall sense of how power hungry it really is.
AMD CPU designs have historically been very power hungry, and I expect the new ones to be no different. Looking at how their 7nm GPUs compare against RTX in power consumption leads me to believe the 3000 series will require quite a bit of juice.
