They must be decades behind, then. I don't think in-house Russian engineering capabilities have been competitive let alone ahead of the consumer electronics curve going back at least a decade in the of fabrication. Maybe when it was 1997 and everything was DIP.
The idea I commented on was to ban Intel chips. Russia cannot do that, military or not. The military accounts for a fraction of a fraction of tech that Russia depends on.
And the military are also dependent on foreign technology. If not for CPUs inside tanks and planes, then for CPUs inside command center computers. (and not just CPUs)
