This became the Intel 8008. Although it required several additional ICs, it is generally known as the first 8-bit microprocessor. The requirements of the Datapoint 2200 determined the 8008 architecture, which was later expanded into the 8080 and the Z80 upon which CP/M was designed. These CPUs in turn influenced the 8086, which defined the whole line of "x86" processors used in all IBM-compatible PCs to this day (2020).
