Both a porterhouse and T-bone steak have a similar shape and coloring. The main difference is the size of the steak and how it's cut, which also results in different prices.

A porterhouse steak features a t-shaped bone that separates what would be the filet mignon on one side and a New York strip steak on the other. Kept together, you get the T-bone.

From the end of the short loin, a porterhouse also has a T-shaped bone and even contains the T-bone's same beefy properties, but the porterhouse is even beefier.
