High-mass star death

How does the death of a high mass star differ from that of a solar mass star? At what point do the events begin to differ? Low mass stars become white dwarfs before they die.  While high mass stars becomes supergiant before their death. The death of high mass stars is more violent as compared to the death of low mass stars. Low mass stars spend more of their life in the main sequence as compared to high mass stars i.e.- 10 billion years and 100 million years respectively. Due to the greater mass, the evolution of high mass stars is faster as compared to the lower mass stars. Stars with lower mass heats up more slowly then stars with greater mass. High mass stars burn more firmly and do not experience the helium flash of solar mass stars. They begin to differ when entering the carbon burning process.
