[Based on this answer in stack overflow](https://stackoverflow.com/questions/47335027/what-is-the-difference-between-cuda-vs-tensor-cores)

They’re both essentially just a part of the GPU that is really good at a certain type of calculation. CUDA cores are good at multiplying two numbers and adding it to another number. Meanwhile, a tensor core is specialized in doing the same but with 4×4 matrices instead.

Both of these types of calculations are heavily involved in rendering traditional raster graphics. They also happen to be very useful in machine learning, which is why you’ll often see GPU used for AI
