Xilinx Zynq and Ultrascale series are multiple Ghz ARM cores plus FPGA. They're incredibly useful for small volume niche use cases and to give an example from my industry, becoming popular in space applications. The reason is hardware qualification/verification is extremely expensive but a change to FPGA fabric is not.
My point is Xilinx have already proven ARM CPU+FPGA on one die and I think AMD CPU+FPGA is very likely to be a success.
Between this, ARM adoption, Apple Silicon and similar offerings (which kind of skipped ARM+FPGA for ARM+ASIC), RISC-V, it's like 1992 again with exciting architectures. Only this time software abstraction is much better so there is not a huge pressure to converge on only 1-2 architectures.
