It depends on the application. Things like terminal guidance systems for hypersonic intercept run on CPUs like an ancient MIPS R3000/4000. It doesn’t need anything more. If you are trying to do real-time processing and fusion of the F-35 sensor suite or an AEGIS system, it is extremely compute intensive and so they live much closer to the bleeding edge with regular upgrades because there is an almost unlimited appetite for more processing power if available to support capabilities.
You often see a mix of really old and really new. They only use the latest greatest, ASICs, or similar when there is an absolute advantage to be gained by doing so. The old platforms are proven and reliable so no reason to not use them if they do the job and they often do.
