Well that's a load of crap, then.
At full-tilt-boogie, the video card ain't the only thing whose power consumption is a variable. The CPU, RAM and motherboard are all going to be cooking, so how can you have any idea what the power consumption of any one device is if you're only measuring the mains power?
It doesn't even account for the fact that the conversion efficiency of the power supply itself is non-linear.
Every modern multi-supply video card has on-board shunts on all of the incoming rails used to drive VCORE
(and whatever other locally-regulated supplies they require), and you can find the specs on then just by looking at the power management IC and pulling up the datasheet for it. How the hell hard is it for these folks to tap across those into a set of high-impedance DC millivoltmeters and read the current directly at the point of consumption?
Here's a typical power supply circuit for a video card which draws from both the PCIe bus and an external ATX connector:
All you need to know is the value of the two leftmost VIS
shunts and you can very precisely measure actual power consumption by simply probing across them while the card is operating.
Fuсking lazy-***, good-for-nothing bloggers can't even be bothered to do a tiny bit of proper engineering, and think a consumer grade AC wattmeter makes them the King of all Metrics. I am the Data Pope, motherfuсker!
