TDP for the 10900F is 65W and for the 3800XT is 105W, so I don't know where you get the "double the watts usage" from.

Intel's real-world power usage bares absolutely no resemblance to their claimed specs.

Mine does.

I wonder how much this depends on BIOS settings rather than innate chip properties.  Different motherboards have very different default settings.

For example, the Skylake i7-6700K is as I recall rated at 91W TDP.  However, at default settings, my Asus motherboard will see it running much higher unless you tweak the long-term and short-term max power settings down.

By contrast, I have an AMD 3900X, also in an Asus motherboard, and at default settings that won't go above the nominal 105W (although you can make it go much much higher if you tweak things).

There seem to be plenty of bloggers grumbling that default BIOS settings in many motherboards (not just Asus) can be rather arbitrary.
