All processors are inherently behind. First research comes out or standards are made, then much time later silicon is fabbed. For example, pcie gen 6 was ratified years ago, but there's nothing I've seen that uses it. Maybe you could argue that their silicon is behind others' but it's all about what their market is and what their customers are demanding.
Also, in the case of the kind of chips we are talking about, the cadence is probably tied to contracts and projects. If the government built supercomputers more often then the chips would get updated more quickly?
