An interesting chart depicting the generational performance per dollar improvement on NVIDIA's GeForce mainstream lineup has been posted over at the NVIDIA subreddit by the user Hic-Stunt-Leones. The chart shows us the gains we have seen since the GeForce 9600 GT, all the way up to the current GeForce RTX 2060.

The mainstream cards are generally what make up the bulk of GPU sales for both NVIDIA and AMD. This mass volume segment is what helps either company drive higher share percentages even if it doesn't offer the same returns as the high-end cards. AMD and NVIDIA have had some competitive offerings released in this segment over the past decade with cards such as the HD 5850, GTX 460, R9 270 series, GTX 970, RX 500 series and the GTX 1060 to name a few.
