Although BK-0010 was one of the cheapest Soviet PCs, and in speed (as well as memory, graphics, and so on) differs little from the simple 8-bit models, it was one of the first fully 16-bit home computers in the world (in contrast to the TI-99/4A, BK had controllers with the same data bus-width). The Intellivision used a very similar, fully 16-bit CPU, the General Instrument CP1600, and with the Keyboard Component or ECS expansions, it was turned into a fully 16-bit home computer. The IBM PC and PCjr were 8/16-bit computers, as their 8088 CPU has an 8-bit data bus and a 16-bit internal bus.
