GPU, Graphics Processing Unit, is the buzz word ruling the market these days. What is that and how has it gained that much importance is what to be answered in this research work. The study has been constructed with full attention paid towards answering the following question. What is a GPU? How is it different from a CPU? How good/bad it is computationally when comparing to CPU? Can GPU replace CPU, or it is a day dream? How significant is arrival of APU (Accelerated Processing Unit) in market? What tools are needed to make GPU work? What are the improvement/focus areas for GPU to stand in the market? All the above questions are discussed and answered well in this study with relevant explanations. © Maxwell Scientific Organization, 2014.
