What is a GPU + Why Do I Care: A Businessperson Guide


This article is a real gem. Written by an expert in GPU technology (MapD builds a SQL database that is powered by GPUs), it goes back to basics in explaining the fundamentals of GPU-based computing. I actually hadn't realized that the primary benefit of GPUs is their massively parallel architecture, which is something of a historical accident:

The reason GPUs exist at all is that engineers recognized in the nineties that rendering polygons to a screen was a fundamentally parallelizable problem - the color of each pixel could be computed independently of its neighbors.

Apparently each GPU chip has thousands of cores, and as such is far superior at handling "embarrassingly parallel" operations. Like analytics.
