Each corner is a ten-point rating. The further out, the higher.

The difference, by ear

The defining difference is the picking hand: thrash downpicks everything and gets a percussive chug, speed metal alternate-picks and gets a smooth blur. The riffs can be identical and the feel is not.

Thrash metal is shouted where speed metal is sung cleanly, at much the same pace, around 180 to 250 bpm. To hear the difference, play Motörhead next to Metallica. Both grew out of heavy metal, speed metal first and thrash metal two years after. Germany appears in the origins of both.

Put together from each genre's vocals, tempo, song length, key acts and place in the tree.
