In CPUs, AMD has made many innovations that have been copied by Intel only after many years and this delay had an important contribution to Intel's downfall.

The most important has been the fact that AMD has predicted correctly that big monolithic CPUs will no longer be feasible in the future CMOS fabrication technologies, so they have designed the Zen family since the beginning with a chiplet-based architecture. Intel had attempted to ridicule them, but after losing many billions they have been forced to copy this strategy.

Also in the microarchitecture of their CPUs AMD has made the right choices since the beginning and then they have improved it constantly with each generation. The result is that now the latest Intel big core, Lion Cove, has a microarchitecture that is much more similar to AMD Zen 5 than to any of the previous Intel cores, because they had to do this to get a competitive core.

In the distant past, AMD has also introduced a lot of innovations long before they were copied by Intel, but it is true that those had not been invented by AMD, but they had been copied by AMD from more expensive CPUs, like DEC Alpha or Cray or IBM POWER, but Intel has also copied them only after being forced by the competition with AMD.
