The great advantage of the Z80 over the 8080 was it's direct(er) interrupt handling and second register set, saving many cycles when used for this. Speeding response time up quite a lot. While interrupt handling was eased on the 86 by having more vectors, it was slower as well due long vectors and register saving. So Z80 could, at similar clockspeeds, still run circles around an 8086. | |

| Apr 14, 2021 at 17:12 | comment | added | Raffzahn | @OmarL Russia cloned the 8086 as K1810VM86 and 88, while East Germany went later for the 80286 and and was already working on 386 prototypes when flow of history changed :)) | |

| Apr 14, 2021 at 5:42 | comment | added | Raffzahn | @Schezuk Would it matter? The switch happened anyway, no matter if one did put an emphasis on the 8080, like the USSR did, or used the Z80 instead, like the GDR did. Both ended up going for 8086 later on. GDR even somewhat faster IIRC. | |
| Apr 14, 2021 at 5:40 | comment | added | Schezuk | I wonder if it's feasible that z80 be inserted into and considered a part of 8008-8080-8086 evolving tree especially for a 3rd party manufacturer such as the USSR. | |
