It's hard to compare the two because of the variety of fuels, and the corresponding variety of fission and fusion reactions. Currently we can't do fusion in a reactor like we can fission. That makes it hard to compare, too.
Roughly speaking, however, you'd get around 4x more energy per unit mass of fuel out of fusion. This is comparing the fusion of deuterium and tritium to Helium, with the fission of U(235) to Rb(90) and Cs(143).
Compared to the total energy in the fuel (i.e. a matter/antimatter annihilation reaction) even the fusion reaction only liberates about 0.4% of the total energy.

∙ 14y agoThe engineering design for a fusion reactor has not been worked out yet, so it's not possible to put a figure on this. It will depend on what type of thermal cycle the plant operates on, but if it is a Rankine cycle it won't be much different to a fission reactor. Higher efficiency can be obtained with higher steam conditions, but what they will be is unknown yet.

Yes, if your intent is to destroy a city, then a nuclear fusion bomb (also known as a Hydrogen bomb) is a very cost effective way to annihilate a city.
No, if your intent is to generate power to service a city, because nuclear fusion has not been harnessed in that way yet.

Is nuclear chain reaction is called fusion?
The idea of nuclear fusion occurring at room temperature is called cold fusion.
How do nuclear fusion differ fundamentally from nuclear fission?
Nuclear fusion doesn't produce energy.
What is the benefit of nuclear fusion and What is one thing nuclear fission and nuclear fusion have in common?
nuclear fusion make more energy and they both make energy and have waste products
What comes after nuclear fusion?
Nuclear fusion is itself a difficult enough one to crack!
Where would you find a nuclear fusion reaction occurring?
You can find nuclear fusion in a star.
How is nuclear fusion an efficient energy source?
It isn't, yet.
A reaction in combining smaller atomic nuclei is?
nuclear fusion
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
What is a nuclearfusion?
Nuclear Fusion, not to be mistaken with Nuclear Fission, is a process in which energy is created due to the merging or "fusion" of subatomic particles. The process is much more energy efficient, and produces larger quantities of energy than in a fission based process.
The process of combining two small nuclei into one nucleus of larger mass is called?
Combining two atomic nuclei is called nuclear fusion.
Is fusion chemical nuclear or mechanical?
Fusion is a nuclear reaction.
Is nuclear chain reaction is called fusion?
The idea of nuclear fusion occurring at room temperature is called cold fusion.
Is fusion nuclear energy or chemical energy?
Nuclear fusion produces nuclear energy
What is combining nuclei of atoms to produce energy called?
That would be nuclear fusion, like what happens in stars, when two hydrogen nuclei combine to form a helium nucleus.
What causes lesser pollution - nuclear fission or fusion?
Nuclear fusion
How do nuclear fusion differ fundamentally from nuclear fission?
Nuclear fusion doesn't produce energy.
Which term is used to indicate the process in which two small atomic nuclei emerge from a larger one?
nuclear fusion
