Depends on which nuclear device your talking about though the largest conventail weapons is the Russian "Father of All Bombs" which is 8 tons and has the equivilent explosive strength of 44 tons of TNT. It is more powerful then the American MOAB which is the same weight accept only yeilds 11 tons TNT since the russians have some advanced fuel which is significantly more explosive then the american counterpart.
Probably the smallest nuke is the American M-28 and M-29 it was 40kg and had the equivilent explosive strength of about 10 tons of TNT.
The largest nuclear missiles in USA service now are generally above 50 tons (with the nuclear fuel being probably only 1% of the weight, thats a guess) and have an equivilent explosive strength of about 1200000 tons of TNT or 1.2 Mt
The largest ever nuclear bomb has Tsar Bomba (early hydrogen bomb) which was 26 tons (10 tons nuclear fuel) and was the equivilent of 5700000 tons of TNT or 57Mt, to put this in perspective it had a fireball with a diameter of 5.3 km, if you were 100 kms away you would still get third degree burns and had the power of all explosives used in WWII times by ten.
So the simplest answer is the largest conventional weapon FOAB about as strong as a small tactical nuke, with current high yield USA missiles being about 30,000 times more powerful, and Tsar Bomba being about 1710000 times more powerful.
theoretically the yield of nuclear weapons is unlimited.
I assume you mean "Soviet bomb" - The Tsar Bomba (Царь-бомба) was detonated on October 30, 1961, in the Novaya Zemlya archipelago. It was the largest, most powerful nuclear weapon ever detonated.
the conventional military is less important than nuclear weapons
A nuclear-powered submarine is different from a conventional submarine because it is powered by a nuclear reactor instead of diesel engines or batteries. This allows it to stay submerged for longer periods of time and travel at faster speeds. Additionally, nuclear-powered submarines do not need to surface as frequently for refueling, giving them greater endurance and operational range.
A large-scale nuclear exchange followed by a conventional war which itself would involve heavy use of tactical nuclear weapons.
theoretically the yield of nuclear weapons is unlimited.
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
Mushroom cloud as the shape resembles an ever growing mushroom.Note that this cloud is in no way unique to nuclear explosions, it is produced by all explosions. The degree and duration of the phenomena is directly proportional to yield, as nuclear explosions have yields several orders of magnitude higher than conventional explosions their mushroom clouds are orders of magnitude more dramatic and memorable.
A nuclear explosion is more powerful than a lightning bolt. Nuclear explosions involve the release of massive amounts of energy from the splitting of atoms, while lightning is a discharge of electricity between clouds and the ground, which is powerful but on a much smaller scale.

Nuclear fusion, the same reaction that takes place in nuclear warheads, only in conventional warheads it's caused by powerful conventional explosives directed inward to cause heavy elements to fuse together, and in the cores of suns (stars) it is caused by the much more powerful force of the star's gravity.
A nuclear arms race.

The Fukushima Daiichi nuclear power plant in Japan experienced a series of explosions in March 2011 following a powerful earthquake and tsunami. The disaster resulted in a significant release of radioactive material and led to the evacuation of surrounding areas.

nuclear weapons of the fission fusion type, the so called H-Bomb, are the most powerful of all weapons but their ouput can be tailored for specific purposes. Whatever their size they are inevitably more powerful than any conventional explosive.
The largest nuclear bomb ever detonated was the Soviet Union's Tsar Bomba in 1961, which had a yield of 50 megatons. It was the most powerful nuclear weapon ever created and tested.
