See that Hardware.fr also reviewed the 1700 and 1700X yesterday.
And they made these nice little volts, clock and watt charts:

Obviously only their samples but interesting anyhow. Seems their 1800X is the best after all as it's able to hit 3.9GHz at 1.275V. The 1.200V data point is the most interesting as not only is the 1800X able to hit 3.8GHz with that rather than 3.7GHz, it does so using the least power too.
Never looked into this, but how much variation would there be at the same clock and voltage? That is taking a different CPU , running it at a set clock and feed it the exact same voltage. Would the wattage be very similar. That is, is the main variation in the silicon lottery mostly the max clock at a certain voltage, but that when clock and voltage are similar the wattage is too?
