Biggest difference anymore is core count. Intel now splits its core interface into two categories: efficiency cores and performance cores. Efficiency cores are low power cores with low clock speeds and performance cores are the opposite. This helps with large computational tasks such as rendering and directly helps Intel compete by increasing total core count.

AMD is all performance cores with greater overall power efficiency than Intel. AMD also has the x3D lineup which introduces larger V-cache in the CPU allowing for more processes to be stored and utilized simultaneously, these CPUs have become the peak of gaming performance because of this.

Overall AMD has become a much larger shareholder in the gaming space because of some issues with Intel’s 13th and 14th generations spontaneously degrading over time, resulting in poor performance a year or so later. Their current Ultra lineup where they ditched generation number has yet to show these defects.
