The chart below shows the generational gains achieved by AMD. Furthermore, there have also been improvements in performance/Watt of course.
Through it, we see a generational performance increase that mostly exceeds the 20% performance points across every iteration of Zen when it comes to both gaming and general computing workloads. This generational improvement hits its (nowadays) most expressive result in that AMD's Ryzen 7 5800X manages to deliver 89% higher general computing, and 84% higher gaming performance than the company's Zen-based Ryzen 7 1800X.

The next step for AMD is the launch of Zen 3+ processors sometime next year. These will be followed up by Zen 4, which is expected to offer DDR5 support sometime in 2022.
