RISC-V is not an architecture, it’s an API ISA.
RISC-V can be built to be energy efficient or fast or cheap top make, just like any other API can have different architectures for those purposes so can RISC-V.
RISC-V can be fast, but it requires massive resources to develop it to be as fast as other leading products.
This maybe true, but it’s also true that are no fast RISC-V devices on the market (even if it is of course possible to develop a fast anything with enough time and resources).
No I repeat RISC-V is an API ISA, and the API ISA is by no means inherently slow. There are no fast RISC-V compatible processors, which is a completely different thing.
It’s like claiming the paper in a printer is slow, when obviously it’s not the paper but the printer.
Because it’s an open API ISA as in actually open, (not bullshit open like OpenAI) and people like that. There are also other factors than speed, like energy consumption, size and price, and of course security, which is becoming a huge issue with traditional products that have back doors.
But for now the major factor is the openness, which means everybody can make one without having to pay license fees to anybody.
