Beyond the most trivial of microcontrollers and experimental designs there are no RISC chips under the original understanding of RISC. The justification for RISC evaporated when we became able to put 1 million, 100 million, and so on, transistors on a chip. Now all the chips called "RISC" include vector, media, encryption, network, FPUs, and etc. instructions. Someone might want to argue that some elements of RISC designs (orthogonal instruction encoding, numerous registers, etc.) make a particular chip a RISC chip. But they really aren't instances of the literal concept of RISC.

To me, the whole RISC-V interest is all just marketing. As an end user I don't make my own chips and I can't think of any particular reason I should care whether a machine has RISC-V, ARM, x86, SPARC, or POWER. In the end my cost will be based on market scale and performance. The licensing cost of the design will not be passed on to me as a customer.
