(I have no clue about the stuff you say about Intel)

I again couldn't find a lot of data on the exports you've mentioned, but I do guess if it's CPUs it was mainly reverse engineered, illegally produced Z80 ("U880").

It looks like the GDR did reverse engineer a 80286 ("U80601") and started limited production in 1989, in very low numbers because of production problems (The West was using 486 at that point). So it is unclear how reverse engineering of CPUs would progress

  Z80 8.5k transistors
  286 134k transistors
  386 275k transistors (+ 120k for 387)
  486 >1200k transistors (the 486 had an FPU)

(As the GDR also illegally cloned DEC MicroVax systems, there is a "U80701" MicroVax clone with 130k transistors, same like the 286 clone. This doesn't seem to have gone into production)

The reason the GDR could not pull it off where manifold. First the Eastern block countries tried a different concept in IT in the 50s and 60s compared to the West, that proved not as practical. Second the GDR lost time by reverse engineering and spending money on smuggling CPUs and machines. Third the West had a huge network of companies building a supply chain for production of semiconductors. The GDR (or Eastern block) would have needed to bootstrap the whole supply chain by it's own. The Western supply chain in semiconductors was probably 1000x the value and people the GDR did or could spend.
