I spent last week-end getting accustomed to CUDA and SIMT programming. It was a prolific time ending up with a Business Card Raytracer running close to 700x faster[1], from 101s to 150ms. This pleasant experience was a good pretext to spend more time on the topic and learn about the evolution of Nvidia architecture. Thanks to the abundant documentation published over the years by the green team, I was able to go back in time and fast forward though the fascinating evolution of their stream multiprocessors. Visited in this article: Up to 2006, NVidia's GPU design was correlated to the logical stages in the rendering API[2]. The GeForce 7900 GTX, powered by a G71 die is made of three sections dedicated to vertex processing (8 units), fragment generation (24 units), and fragment merging (16 units). The G71. Notice the Z-Cull optimization discarding fragment that would fail the Z test. This correlation forced designers to guess the location of bottlenecks in order to properly balance e
