10 W is the the TDP, a fudged estimate of the maximum power, for x86 chip. Idle power is much, much lower and that's really the important part that the Raspberry Pi can't match because anecdotally it has minimal power management capabilities and therefore runs at full power (~4-5 W) whether idle or active. An x86 system can beat that.
