A lot of the yield in H-bombs actually comes from the fission of the depleted uranium tamper - in the Ivy Mike test (the first real multi stage H-bomb) 77% of the yield was generated this way:

The Tsar Bomb test was restricted to 50Mt by missing out the 3rd stage - so it was primarily a fusion device. Had the depleted uranium tamper been in place it would have given the 100Mt the design was capable of - but with horrific fall-out.
