I don't know the exact specs, but but you must compare apples to apples.
The B787 will eventually come in 3 different sizes. The ones we are
getting only has around 230 seats. (smallest of the 3 versions) However,
it will have incredible range...somewhere around 7000 NM. I believe the
A350 (basically an upgraded A330) will have 300+ seats. So if you are
comparing passengers carried per fuel burned, the A350 looks pretty
good. However, if you compare fuel burned per mile traveled, the B787 wins.

Much of the fuel savings on the B787 is do to the fact that bleed air
from the engines will be used only for thrust. Pressurization, airfoil
anti-ice, etc. will all be electric. This will save a ton of fuel.
Also, the B787 is composed mostly of composite material, making it very
light.
