Swords breaks blocks faster than hand

When I was in my survival world I went to break some dirt but realized that i was using my sword so i switched to my hand (because i didn't have a shovel) but i noticed that i was breaking the dirt slower with my hand. So i went to my creative world and placed a few lines of different blocks blocks (i used dirt, stone, packed ice, glass, crafting tables, and warped fences.) and timed it and found that i broke all the blocks faster with the sword than my hand.

I know that blocks like cobwebs and leaves are broken faster with a sword than with hand but i expected that the sword would break other blocks at the same speed as with my hand
But when I tested the sword broke the blocks faster than my hand did
