Although many tend to equate the two subgenres, others argue that there is a distinct difference between them.

With the sudden boom of fast, raging bands, however, it sometimes helped to distinguish between the throbbing, rhythm-heavy thrash metal and something a bit cleaner and more melodic--dubbed speed metal." Some may argue that first wave black metal bands such as Venom, Sodom, and Bathory were speed metal and that black metal evolved as an extreme form of speed metal.
