digital logic - Is there a name for "chips out of which one can build a CPU"?

Some people enjoy building "homebrew" CPUs out of simpler ICs.

Is there a name for "chips out of which one can build a CPU, if you have enough of them"? Is there a name for the other chips, "chips that one cannot build a CPU out of, no matter how many of them you have"?

One can build a CPU out of sufficiently large quantities of 4:1 mux chips ( multiplexers are the tactical Nuke of Logic Design ). One can build a CPU out of (somewhat larger) quantities of 2-in NAND gates. Or from 2-in NOR gates. Or from a few (perhaps one) CPLD or FPGA.

However,

One cannot build a CPU out of 2-in XOR gates alone. One cannot build a CPU entirely out of diode-resistor logic alone. One cannot build a CPU entirely out of D-type flip-flops alone.

Is there some term or phrase for distinguishing these two categories of chips that is less awkward than "chips out of which one can build a CPU"?
