Intel and AMD have been competing in the Desktop/HPC, Server, and Laptop Market for more than 2 decades now. For the most part, Intel has dominated AMD and was a clear winner. While AMD took the lead a few times but in the past 10 years, Intel stayed on the top.
One of the primary reasons for AMD's failure was poor IPC & Single-Threaded Performance on their FX Chips. Intel's Core-i Processors dominated the AMD FX CPUs for almost 7 years. But in 2017, AMD came back strongly with their new Zen Architecture and launched new lineup of CPUs like Ryzen (Desktop/Laptops), Threadripper (HEDT), and Epyc (Servers).
During the time when AMD launched Ryzen, it launched 8-core Ryzen 7 chips that defeated the Intel's Core-i7 Quad-Core chips. With Ryzen, AMD became the new king of Price-to-Performance and Multi-Core Performance. However, Intel continued to dominate AMD in Single-Core Performance.
Finally in 2019, when AMD launched their new 7nm Zen 2 based Ryzen 3000 Series, it went far ahead of Intel in Multi-Core performance and matched their Single-Core performance. This was a huge leap for AMD and managed to come out on top. One of the reasons why AMD managed to be so successful is due to the delays in Intel's long awaited 10nm Fabrication Node.
In 2020, Intel is expected to take back the Single-Core lead with their 10th Generation Comet Lake CPUs but unfortunately the Desktop parts will still be based on 14nm and Intel's victory will be short lived until Zen 3 arrives.
In 2021, AMD could further shrink their CPUs to 5nm and it is uncertain whether Intel will be able to reach 10nm by then or not. If Intel fails to do so, AMD could easily take a big lead which would be not easy to overcome for many years,
As of 2019, AMD's Processors seem the best bang for a buck for all kinds of Workloads including Content Creation, Gaming, Productivity, and other kinds of work. But Intel CPU's only seem suitable for systems that are built exclusive for Gaming.
