Stream Processor Definition

Stream processors are what video cards use to process the image on the screen. Doubling the stream processors can achieve very close to double the performance. Each one is similar to a core on a CPU but much less powerful. There are several other major factors in determining the final performance of a video card.

Note: Not all stream processors perform the same. Nvidia usually uses fewer but more powerful stream processors than AMD. In the end, both company's video cards perform close to the same.
