The F35 is a massive network of independent computer systems, you seem to be using “computer power” rather abstractly. Some of the computing components are state-of-the-art and others are rather old, based on requirements. Who cares if a computing component is slow if it doesn’t need to be faster than it already is. Other parts of the F35 exceed the capabilities of anything you can buy off-the-shelf. The need to upgrade many of these computing systems is bottlenecked by the ability to upgrade the sensor systems that would necessitate upgrading the computing systems. Also, you are talking about “mega” and “giga” when many modern US systems are “peta”. With all due respect, you might be working from an obsolete understanding of these systems.
