why do these two cards have such different power draw? one runs at 150 W and the other at 215 W. they both have the same GPU running at the same frequency.
1506 MHz Base Clock
1683 MHz Boost Clock
Memory: 8192 MB, 256 bit GDDR5, 8008 MHz (effective)

Probably since the more expensive model has a less efficient yet more cleaner power delivery circuit. Basically to achieve better overclocks you need stable as hell voltage, which in turn requires more complex and less efficient circuitry, more loss to heat and vice-a-versa.

can you explain why

Because if you have stable circuitry it has very little tolerance for additional voltage. If you have more inefficient circuitry which allows leakage which acts as a cushion. Think of a balloon, more stretchy the material more air it can handle

>such different power draw?
under normal circumstances there will only be a slight difference in power draw due to the FTW card being slightly OC'd more.
That being said, you notice the power phase is 10+2 on the FTW card, thus enabling a higher POSSIBLE power draw meaning more potential for overclocking by the customer.
What they are saying is, the 1070 FTW is capable of that power draw VS a typical 4+1 Phase card.
Again, it will hardly draw more power in factory stock form VS a reference 1070.
